Description

FIELD OF THE INVENTION [0001] The present invention is related to a programmable device for electrical power. In particular, the programmable device may be useful for electrical power outlets. Further, the programmable device may be especially useful for domestic power outlets.

BACKGROUND OF THE INVENTION [0002] Electrical power is supplied to electrical devices, such as televisions, stereo systems, toasters, ovens and other domestic and non-domestic appliances, through power outlets, which usually are equipped with manual switches to allow turning on and turning off of the mains power supply to the electrical device. Further, lighting is controlled by electrical switching devices (often simply referred to as a light switch), which allows power supply to be turned on and turned off to the light.

[0003] Some electrical switching devices (power outlets, light switches and other like electrical switching devices) have only provided means for manually switching the power supply on and off. However, such manual switches do not provide for any automated switching, as is often desired by a user. Such automated switching may be desired for the purposes of power saving, switching electrical devices and lights on and off during absences from a property to simulate the effect of people being present for security, or for other purposes.

[0004] Automated switching devices include mechanically or electrically operated timing devices, which can be plugged into a power outlet and then set to control the timing of when power is supplied to and cut off from an electrical device, such as a lamp. Electrical or mechanical timing devices for plugging into power outlets are problematic in that they are bulky, they are difficult to program, they do not have many programming options for on and off power periods, and they are often inaccurate. Another problem with mechanical devices is that they produce a lot of noise, they are expensive, and they are not energy efficient because they consume a lot of power in operating a motor for the timing device.

[0005] Other devices include large, complex and sophisticated centralised power control systems, which are very expensive and complicated to install in a building which is being constructed. Such complex centralised power control systems are also much more complicated to install (retro-fit) in

2018200919 07 Feb 2018 an already-built property. Further, these systems are difficult to program, as they often include many control options.

[0006] A problem with devices, as discussed above, is that they do not result in sufficiently effective saving of electrical power. Some of the devices are stated by manufacturers or others to be power saving devices, but, even if they do save power, the amount of power saved is relatively small. Often the devices do not result in a net saving of power due to the device itself consuming too much power during its operation.

[0007] One example prior art device is identified in European Patent Application No. 384881 (Al), in which the device is primarily addressed to safe operating. However, the device is relatively complex and contains many electrical components, which would result in a device which consumes a relatively large amount of electrical power in operation. Further, the device of this document does not include any sort of timing mechanism for switching on and switching off the electrical power supply.

[0008] Yet another example prior art device is disclosed in US Patent No. 5,278,771, which is a large device, again having many complex electrical components, which results in consuming relative large amounts of electrical power during operation. This device comprises a programming interface built into the device, which is not always readily accessible when the device is being used. Further, the programming interface is not simple to use and there is only one interface that can be provided with such a device, such that it is not possible to use other interfaces for programming the device according to a user's choice. Moreover, the device is configured so as to be completely external to an electrical power supply socket. Due to being situated externally, the device cannot operate particularly efficiently in order to save power with its timed power supply.

[0009] Yet another example prior art device is mentioned in US Patent No. 7,964,989, which comprises a unit that is completely external to an electrical power supply socket, and is plugged into such a socket, with an electrical device, such as a lamp, being plugged into the unit. The device of US Patent No. 7,964,989 is able to be operated by a remote control device, such as a computer tablet. However, the device does not have any in-built timing, so is restricted to being operated directly whenever a user desires to switch on or switch off electrical power supply, to, for example, a lamp.

In this regard, the device is unable to accept any programming instructions for operating times, wherein those times are stored within the device. Accordingly, for timed operation, this device would need to operate in conjunction with the computer tablet, wherein the tablet holds any timing instructions. This results in a problem that for timed switching operation, the device and the

2018200919 07 Feb 2018 computer tablet must always be used together, which is likely to be an inconvenience for a user, and relies on the computer tablet to be working and operational during such desired switching periods. Further, this device, being externally located from the electrical power supply socket, has a similar problem to the device identified in US Patent No. 5,278,771, being that, as an external unit, it is relatively energy inefficient, and would not lead to sufficient saving of electrical power during operation.

[0010] It is an object of the present invention to overcome, or at least ameliorate, at least one of the above-mentioned problems in the prior art, and/or to overcome, or at least ameliorate, at least one problem in the prior art, which has not been mentioned above, and/or to provide at least a useful alternative to the prior art devices, systems and/or methods.

DETAILED DESCRIPTION OF EMBODIMENTS OFTHE INVENTION [0040] FIG. 1 shows an example implementation (embodiment) of the present invention. In this embodiment, the programmable electrical control device 10 is implemented for controlling electrical power supply for an electrical switching device (a domestic power outlet) 12. The electrical power outlet includes a body (not shown) a face plate 13 and manual switches 16 for turning on and off mains power supply through the power outlet sockets (GPOs) into which are inserted plugs 14 of electrical devices (a fridge 18 and a visual display unit 20).

[0041] FIG. 1 also shows various methods and devices (program input devices) by which instructions for switching times for the electrical switching device 12 may be input to the programmable electrical control device 10 by an external programming device.

[0042] In one embodiment, the data connection module is a USB port 22a. In this embodiment, the USB port is shown connected to a laptop computer 24a via a USB cable 26. The laptop computer contains programming software for programming the programmable electrical control device with instructions for switching times to be communicated via a chosen communication protocol over USB. The software may also be able to receive information transmitted from the programmable electrical control device via the USB port 22a, including a present state of switching times for the programmable electrical control device 10.

[0043] In other embodiments, the external programming device may be, for example, a smartphone 24b or a laptop computer 24c. Such external programming devices may communicate with the programmable electrical control device 10 each via either a Wi-Fi® link 22b or a Bluetooth® link 22c, using the appropriate communication protocol. Similarly to the embodiment where the program input is a USB port 22a, the Wi-Fi® link 22b and the Bluetooth® link 22c may allow both transmission of signals carrying instructions for switching times (switching time data) from the external programming device to the programmable electrical control device 10, as well as transmissions from the programmable electrical control device 10 to the external programming device 24b, 24c. The transmissions from the programmable electrical control device 10 showing, for example, the present state of switching times.

[0044] In other embodiments of the present invention, the external programming device may be a tablet, such as an iPad®, an Android® tablet or smart phone device, or similar devices. Further, the external programming device maybe a remote control communicating via infrared, or any other suitable device, which can communicate via wireless or non-wireless means.

2018200919 07 Feb 2018 [0045] In a further example embodiment, the programmable electrical control device 10 may also include an indicator for showing connection to a program input device via Wi-Fi® 22b or Bluetooth® 22c. In the embodiment shown in FIG. 1, the indicator is a light 28, which is located in the faceplate 13 of the power outlet 12.

[0046] FIG. 2 shows an embodiment of the programmable electrical control device 10, which is implemented in an electrical power outlet having two outlet sockets 15 (the terminals of the outlet sockets are not visible in FIG. 2), also known as GPOs. The electrical power outlet 12 is a domestic type power outlet including a based plate 30, bus bars 32 and a back housing 36. The programmable electrical control device 10, in this embodiment, includes a printed circuit board 34 (PCB), which include hardware components of the device 10.

[0047] In this embodiment, the electrical switching device (power outlet 12) includes a Bluetooth® pairing indicator 28, which may be an LED configured to indicate when the device 10 and an external programming device are in a paired state.

[0048] It can be seen in FIG. 2 that all of the main components of the device 10 are fully integrated within the body of the electrical switching device (power outlet 12). In this way, the electrical power outlet 12 can be sold with the programmable electrical control device 10 as a single unit. Furthermore, providing the programmable electrical device within the electrical switching device should result in a more efficient operation for the programmable electrical control device, thus leading to savings in power consumption. In this regard, the programmable electrical control device is located between the electrical power supply input and each electrical power supply output (in Figure 2 the electrical power supply output comprises the outlet sockets 15). This configuration can be compared with prior art configurations, wherein allegedly power saving devices are located externally to the electrical switching device (the power outlet socket), which results in relatively inefficient operation and consumption of more electrical energy for that operation.

[0049] FIG. 3 is an example screen shot for an operating interface 38 in a software application, which can be run on an external programming device, such as a laptop, a smartphone, or other like computing devices.

[0050] To the left of the operating interface 38, there is a switch list 40, which includes the switch names 42 of electrical switching devices that include the programmable electrical control device 10, and are therefore available for programming by the external programming device. For example, the switch name may be KITCHEN, thus indicating that the switch is located in the kitchen, the switch name 42 can also operate as a button, which can be clicked to cause timing and other details of that

2018200919 07 Feb 2018 particular switch (or GPO having a device 10) to appear in the right hand side of the operating interface 38.

[0051] In the right hand side of the interface 38 there is shown a switch on/off indicator 44, with an ON indicator 46 and an OFF indicator 48. There is also a button 50 for selecting between an SIMPLE or ADVANCED interface display. In the embodiment illustrated, the SIMPLE interface 38 is shown.

[0052] The interface also includes days of the week indicators 52, along with an indicator 54 to show which day of the week is selected to be programmed. In this example, the day of the week selected is WEDNESDAY.

[0053] Below the days of the week 52, there is shown the start and stop programming facilities, with a TIMER START button 58 above which is the selected day of the week (WEDNESDAY) 56. Next to the TIMER START 58 there is a time list 60 in one minute increments, along with a forward/back time selection scroll button 62.

[0054] Similarly, below the start programming facilities, there are the stop programming facilities, including an indicator of the selected day of the week 64 and the TIMER STOP indicator 66, along with the time list 68 and the forward/back time selection scroll button 70.

[0055] As shown in this example operating interface 38, the switch (or GPO) name can be shown in multiple locations for clarity. It will be also understood that where icons, words or numbers appear on the operating interface 38, these can function as indicators only or as indicators and clickable buttons. Such clickable buttons can operate in software applications to cause data entry, changes and/or deletion, and can also operate to cause the software application to display a new interface, or a new part of the interface.

[0056] FIG. 4 is a diagrammatic representation 80 of main system components (subsystems) in an embodiment of the present invention. The components in this embodiment include a trigger 82, a power supply 84, a general purpose outlet (GPO) 86, which may also be described as a power socket or power outlet socket, a Bluetooth® transceiver 88 for communicating switching time data between the programmable control device 10 and an external programming device (via a user interface) 92, the communication being by radio frequency (RF) signals 90. The device 10, in this embodiment, also includes a microprocessor 94, which in certain embodiments, may be co-located in a single unit with others of the components/subsystems. The device 10 also includes a mains power control 96,

2018200919 07 Feb 2018 including a switching module controlled by the microprocessor 94 (also simply referred to as a processor).

[0057] FIG. 5 is a diagrammatic representation of a circuit layout (circuit typology) 100 for an embodiment of the present invention. The circuit has mains electrical supply 102 (also referred to as an electrical power supply input), with in this embodiment and other described embodiments is alternating current (AC). The components in the circuit include a real-time clock (RTC) 104, also described as a timing module, an offline power supply 106 for providing appropriate power supply (typically a stepped-down direct current (DC) electrical supply) to the microcontroller unit (MCU)

108. The circuit diagram 100 also shows two sockets, a first GPO 110 and a second GPO 112. The device 110 can allow or prevent power supply to the GPOs 110,112 by operation of a respective first relay 114 and a second relay 116. The relays are controlled via the micro controller unit 108.

[0058] The circuit diagram 100 also shows the first GPO switch 118 and the second GPO switch 120, which are diagrammatic representations of the manual switches in the electrical switching device. In this embodiment, the circuit also includes a first GPO switch detect 122 and a second GPO switch detect 124, which are for detecting whether the respective GPO is switched on or switched off.

[0059] The device 10 also include a power outage capacitor 126 for powering the RTC 104 during, for example, blackouts or other power-off events.

[0060] The MCU 108 incorporates a low power Bluetooth® transceiver 128, including a Bluetooth® antenna 130 for communicating switching time data between the programmable electrical control device 10 and an external programming device.

[0061] FIG. 6 is another diagrammatic representation of 140 of a circuit typology for an alternative embodiment of the present invention. In this representation 140, the different components of AC electrical supply are indicated, including neutral indicator 142, ACTIVE indicator 144 and EARTH indicator 146. It will be understood that these represent the common labels applied to a three component AC Power Supply in Australia, but could also represent other similar types of power supply in other regions. In FIG. 6, the thicker lines and arrows represent the components 142, 144 and 146 of the mains AC power supply.

[0062] In FIG. 6, the diagram 140 includes a LED indicator 148, which show that the device is in

Bluetooth® pairing state with an external programming device. The Bluetooth® pairing is activated with a button 150, and Bluetooth® communication is received with an antenna 152.

2018200919 07 Feb 2018 [0063] In this embodiment, the device 10 includes an offline AC/DC regulator 154, which may be a low drop-out regulator for stepping down voltage for powering the MCU 108. This is done to allow an energy storage system (the energy storage and charge controller 166) to be charged to a higher voltage as required for powering the RTC 104 for the required duration during a blackout event. The device 10 also includes a mains clock synchroniser 156, which is able to synchronise the RTC 104 using the frequency of the AC mains power supply.

[0064] The diagram 140 also shows a first outlet switch monitor 158 and a second outlet switch monitor 160 for indicating whether the outlet switches 118 and 120 are switched on or switched off. The programmable electrical control device 10 is able to allow or prevent electrical power to be supplied to the GPOs 110,112 by AC power switches 162 and 164. These AC power switches may be implemented as relays, latching relays or mains switching TRIACs. It will be understood that a TRIAC is regarded as being superior to either relays or latching relays in speed of operation, connectivity to a micro controller, package size and cost. However, a TRIAC has a disadvantage in drawing power when turned off and dissipating energy when switched on.

[0065] In the diagram 140 there is also shown DC indicators 168, which indicate that a DC electrical power supply is flowing from the offline AC/DC regulator 154 to the energy storage and charge controller 166, a DC electrical current flowing from the energy storage and charge controller 166 to the MCU 108. The diagram also shows SW on indicators 170 demonstrating communication of a switched on state from the outlet switch monitors 158,160 to the MCU 108. Also shown in the diagram is a POK indicator, which is a power ok communication from the energy storage and charge controller 166 to the MCU 108.

[0066] It will be understood that the hardware designs, components and circuit layouts depicted diagrammatically in FIG. 5 and FIG. 6, are intended to result in low power consumption in operation, so as to result in net power saving when programming the device 10 to switch off power as often and as long as possible as desired by a user. In this regard, the particular topologies and components are selected and designed for maximum reduction of power during operation, given other restraints and considerations, such as mandated safety compliance and cost of manufacture.

[0067] FIG. 7 is a diagrammatic representation 180 of a detail in the circuit typology for a basic RTC AC mains clock synchronisation circuit. The clock synchronisation circuit includes a clock synch 182, a ground 184 and a Schmitt trigger of 86.

[0068] Similarly, FIG. 8 is a diagrammatic representation of a circuit typology 190 for an outlet switch monitoring component, also having a Schmitt trigger 192.

2018200919 07 Feb 2018 [0069] FIG. 9 is a diagram 200 showing component layers for a system in accordance with an embodiment of the present invention. The system includes various layers, including an application layer 202, an application logic layer 204, a driver layer 206, a hardware layer 208, along with external device(s) 210.

[0070] The application logic layer 204 is contained within the application layer 202 and interacts with components in the driver layer 206. The driver layer includes a configuration manager 228, a flash memory driver 230, a Bluetooth® driver 232, an event manager 234, a general purpose input output (GPIO) driver 236, and a hardware timer driver 238. The hardware layer 208 includes a Bluetooth® 240, a crystal 242, a voltage regulator 244, Bluetooth® pairing button 246, a Bluetooth® pairing LED 248, a first outlet switch monitor 250, a first AC power switch 252, a second outlet switch monitor 254, a second AC power switch 256 and a mains clock synchroniser 258. The external devices 210 include a Bluetooth® smart device 260.

[0071] In the diagram of components 200, it is shown that configuration data 212 is exchanged between the configuration manager 228 and the application logic layer 204. Wireless data 214 is communicated between the Bluetooth® driver 232 and the application logic layer 204. Commands 216 are communicated from the application logic layer 204 to the Bluetooth® driver 232. Updates 218 are communicated from the application logic layer 204 to the RTC 224 and time (including clock time/calendar dates) 220 is communicated from the RTC 224 back to the application logic layer 204. Events 222 are communicated from the event manager 234 to the application logic layer 204. Again, commands 226 are communicated from the application logic layer 204 to the GPIO driver 236.

[0072] Within the driver layer 206 there is communication between various of the components, including: resets 262 from the flash memory driver 230 to the configuration manager 228 and rights to 64 from the configuration manager 228 to the flash memory driver 230. The Bluetooth® driver 232 communicates Bluetooth® events 265 to the event manager 234, the hardware timer driver 238 communicates tick events 268 to the event manager 234 and the GPIO driver 236 communicates GPIO events 270 to the event manager 234. The event manager further communicates tick events 266 to the RTC 224.

[0073] The following communications occur between the components of the hardware layer 208 and components of the driver layer 206. The Bluetooth® antenna 240 communicates Bluetooth® RF 272 to the Bluetooth® driver 232, the crystal 242 communicates timing 274 to the hardware timer driver 238, the voltage regulator 244 communicate POK (POWER OK) 276 to the GPIO driver 236, the Bluetooth® pairing button 246 sends a pairing switch press communication 278 to the GPIO

2018200919 07 Feb 2018 driver, the Bluetooth® pairing LED 248 receives on/off information from the GPIO driver, the first outlet switch monitor 250 sends on/off information to the GPIO driver, the first AC power switch 252 receives on/off communications 284 from the GPIO driver, the second outlet switch monitor 254 sends on/off information 286 to the GPIO driver, the second AC power switch 256 receives on/off information 288 from the GPIO driver and the mains clock synchronisation 258 sends a pulse 290 to the GPIO driver 236.

[0074] There is Bluetooth® RF communication 292 between the Bluetooth® smart device 260 in the external devices layer and the Bluetooth® antenna 240 in the hardware layer 208.

[0075] It will be appreciated that the PCB of the programmable electrical control device, along with the components on that PCB, will be formed to take a shape as needed to integrate the PCB and components into a GPO, in such an embodiment. It will also be appreciated that the PCB, due to its relatively small size, may have inherently small gaps between conductors in the PCB, thus increasing the risk of dendritic growth and fouling (creepage) between the PCB tracks. A standard power point does not commonly have this issue due to large and widely spaced metal bus bars. Accordingly, in embodiments, it is envisaged that extra PCB insulation may be an advantage. In one optional embodiment, the PCB insulation may be achieved by insulating the PCB, as a module, in a potting compound during manufacture.

[0076] One possible micro controller unit (MCU) to be used in the programmable electrical control device 10 is a Texas Instruments® CC2541. This particular MCU provides an integrated Bluetooth® low energy transceiver (Bluetooth® v 4.0 compliant protocol stack), along with general purpose I/O including GPIO pins and ADC channels. This MCU is specified as having relatively low power consumption, being only 1 μΑ during sleep mode with the internal RTC operating (if used).

[0077] Since the electronics may be enclosed in an insulating enclosure, a non-isolated AC/DC power supply may be used. An example power supply is the Monolithic Power Supplies® 156, which provides a single chip power supply with minimal supporting componentry supplying up to 3W of regulated DC output power from 85-265VAC, 50-60 Hz input supply. As it is a switching regulator, the MP 156 also has the advantage of being more efficient and consuming less power than nonswitched power supply designs over the operation temperature range of about -40 to +125°C.

[0078] In one embodiment, a low drop-out regulator (voltage regulator) may be used to step down voltage for powering the MCU. This is done to allow the energy storage system to be charged to a higher voltage, as required, for powering the RTC for the required duration during, for example,

2018200919 07 Feb 2018 a blackout event. An example voltage regulator is the Fremont Micro Devices FT5311A, which is a low quiescent current low drop-out regulator (LDO) rated up to 6V.

[0079] It will also be understood that it may be required to change the standard internal layout (including internal bus bars) of a GPO in order to accommodate the additional electronics of the programmable electrical control device. In an embodiment, two mains outlet switches are retained to control each outlet in series with the mains power controls switching element of the programmable electrical control device, along with the rear screw type wiring terminals.

[0080] To switch the mains outlets, the programmable electrical control device may use a relay, a latching relay or a mains switching TRIAC. One example relay is the TE Connectivity® RTD14005F, which has a switching rating of 16A at 250VAC, and a maximum switching voltage of 400VAC.

Further, this relay has a mechanical endurance rating of 30 x 10^scycles and a circuit break rating of 30 x 10³ cycles at 16A at a temperature of 85°C. Assuming an average of two switching cycles per day over a 15 year period, such a relay would operate to approximately 11,000 cycles.

[0081] Alternatively, if using a latching relay, one example is the TE Connectivity® 8-1393239-6 latching relay. However, such a relay is typically more expensive than a standard relay.

[0082] Another alternative is using a TRIAC, which is superior to relays in speed of operation, connectivity to an MCU, package size and cost. However, a disadvantage of a TRIAC is that is draws power when turned off and dissipates energy when switched on. An example TRIAC is the NXP Semiconductors® BTA316B-800B, 118.

[0083] To provide RTC clocking synchronization from the mains AC supply, a Schmitt trigger circuit may be used. An example of such a Schmitt trigger is the Fairchild Semiconductor® NC7NZ17. Further, an example RTC is the NXP Semiconductors® PCF2123BS/1,512. This RTC has relatively low current of lOOnA when run from a backup power source, hence minimising the size of the required RTC battery or capacitor. Alternatively, if an internal MCU RTC is used instead of the low current external RTC, brown-out protection time will be reduced to 10%. This may be advantageous in some circumstances.

[0084] In some embodiments, to allow the RTC to operate for a minimum of 72 hours during an electrical blackout, an energy storage component may be used. An example energy storage component is a lOmF, or larger capacitor, which should provide a requisite battery lifetime when powering the RTC. An example capacitor is the Panasonic Electronic Components® ECA-1AM153, which is an aluminium electrolytic capacitor. However, one disadvantage of such a capacitor is its

2018200919 07 Feb 2018 physical size and diameter, being approximately 18mm and having a height of approximately 12.2mm. Other smaller capacitors may be used, which have less capacitance.

[0085] In an embodiment, the programmable electrical control device includes means to monitor AC voltage for each outlet (GPO) to determine if an outlet switch is either on or off. A Schmitt trigger may be used for this purpose, as shown in Fig. 8.

[0086] In an embodiment implementing Bluetooth®, a Bluetooth® pairing button can be implemented by using the outlet switch (manual switch) of the GPO in conjunction with the outlet switch monitor. A change of either manual switch (in a two switch/two GPO electrical outlet) from on to off then back to the on state would activate the Bluetooth® pairing mode.

[0087] It has been found that the components as shown in FIG. 6 may draw up to 30mW of power from the mains supply in a no-load condition. This may be equivalent to the state when both power outlets are turned off and the MCU is operating in low power mode, with only the RTC timer running. Depending on the outlet switching solution (the switching module) chosen, additional idle power losses may be incurred. If a TRIAC is used, this may add up to 0.5mA leakage current per TRIAC. At 240VAC, this would result in an additional power loss of 0.24W.

[0088] If using a relay for the switching module, it will be recognised that relay switches have no off state idle leakage. However, when actuated, a relay draws about 0.4W continuously.

[0089] If using a latching relay for the switching module, this only uses power to switch from one state to the other state. This may be considered in some embodiments as a most efficient solution.

[0090] FIG. 10 shows a flow chart 300 for the operation of software on an external programming device, such as a laptop computer or a smartphone. A user operating the software activates the software using a start/stop control 302, which may be implemented as a clickable screen icon. The software will then display 304 detected programmable electrical control devices 10 within the vicinity of the external programming device. The user can then select 306 a particular programmable electrical control device 10 for configuration, wherein the software detects whether the device has been selected 308. If the answer is YES 334 then the software can retrieve the device configuration 312 and then displays the device configuration 316. If the device is implemented in an electrical switching device with two electrical power supply outputs, then the user can select 320 which output (for example, the left output or the right output) is to be configured, and then the software displays 324 the configuration for that particular electrical power supply output.

2018200919 07 Feb 2018 [0091] When the configuration for time output is displayed 324 the user can set on/off days and time intervals 326, represent periods of supply on and supply off controlled by the device 10. When the switching times are input by the user 326, the software can upload the switching time data by communicating 328 the switching time data from the external programming device to the data connection module of the programmable electrical control device. The software then detects whether the configuration has been uploaded (communicated) 330 if the answer is YES 342 then the software operates to display the detected devices 304. If the answer is NO 340 then the software acts to retrieves the programmable device configuration information 312.

[0092] Returning to the decision point in the software of whether the particular device has been selected by the user 308, if the answer is NO 332 then the software can act to detect devices 310. The software will then determine whether a device has in fact been detected 314. If the answer is NO 336 then the software will return to the display of detected devices 304. If the answer is YES' 338, then software can act to adjust the device clock 318 and then act to add the device to the device list 322, where upon it returns to the display of detected devices 304.

[0093] It will be understood that the software flowchart 300 in FIG. 10 is only an example of how software could operate on an external programming device. It will be understood that the external programming device and its software do not constitute part of the programmable electrical control device 10, but may be implemented as part of an electrical control system including the programmable electrical control device and the external programming device with its operating software.

[0094] FIGS. 11 to 22 are representations of a smartphone 350 with a screen 352 displaying a number of different aspects of a software interface. A smartphone 350 is an example of an external programming device, which operates with the programmable electrical device 10. The smartphone 350 includes a smartphone operating button 354.

[0095] All the interface screens 352 display a product logo 356 for the programmable electrical control device and/or a particular software product for operating on the external programming device to program the programmable electrical control device 10.

[0096] FIG. 11 shows a screen indicating DEVICE DETECTED 358, which indicates that at least one programmable electrical control device has been detected by the software.

[0097] FIG. 12 shows a screen in the software inviting the user to CONNECT? 360, with YES

362 and NO 364 screen buttons.

2018200919 07 Feb 2018 [0098] FIG. 13 shows a screen of the interface including a SET TO DEFAULT screen button 366 and a SET PROGRAMMING FUNCTION screen button 368. If the user chooses SET TO DEFAULT, the software can use a default programming setting including standard switching times and can communicate those switching times from the external programming device to the programmable electrical control device through the data connection module. If the user selects SET PROGRAMMING FUNCTION, then the user can set the supply on periods and supply off periods for selected days and times.

[0099] FIG. 14 shows a screen of the interface indicating that the software is operating for SYNCHRONISING TIME AND DATE 370 and show a progress indicator 372.

[0100] FIG. 15 shows a screen of the interface displaying to the user that the SYNCHRONISING TIME AND DATE has been SUCCESSFUL 374, along with a success indicator 376, being a tick symbol.

[0101] FIG. 16 shows a screen of the interface inviting a user to select to PROGRAM 378 either a LEFT or RIGHT outlet socket 380 in an electrical switching device, such as a general power outlet.

[0102] The user can select either the LEFT OR RIGHT power outlet, such that switching times for that power outlet can be programmed into the software and then communicated as switching time and data between the external programming device and the data connection module in the programmable electrical control device for controlling the supply on period and the supply off period for that chosen power outlet. The software then displays a screen as shown in FIG. 17 which is adapted to receive input to SETTIME TO SWITCH ON 382. The interface screen includes screen buttons for selecting the clays of the week (Monday, Tuesday, Wednesday, Thursday, and Friday) 384, along with the days of the weekend (Saturday and Sunday) 386. Each of the days has an indicator below the day name to show whether that day has been selected. In this example, the black circles represent selected days, and the white circles represent non-selected days. The screen also includes an hour input selector 388 a minute input selector 390 and an AM/PM selector input 392. When the user has selected the days and the switch on time for those days, the user can then press the SET screen button 394 to update the configuration information in the software for the chosen outlet socket in the electrical switching device. Similarly, FIG. 18 shows a screen which allows the user to SET TIME TO SWITCH OFF 396, which has all the day and time entry buttons and indicators as for the set time on screen in FIG. 17.

[0103] Once the user has input desired switching times for the supply on and supply off periods for the selected socket in the electrical switching device, the software can then display a screen as in

2018200919 07 Feb 2018

FIG. 19 asking the user DO YOU WANT TO PROGRAM THE OTHER SIDE? and provide a YES screen button 400 and a NO screen button 402 for pressing by the user. If the user clicks YES 400, then the software will return the screens of FIGS. 17 and 18 to set the on and off switching times to be programmed into the programmable electrical control device to operate the socket on the other side of the electrical switching device. If the user selects NO 402, then the software will perform an optional SYSTEM CHECK 404 and display a system check progress indication 406, as shown in FIG. 20. FIG. 21 shows a screen wherein the software has determined SYSTEM CHECK SUCCESSFUL 408 with an additional indicator 410, being a tick.

[0104] At the end of the operation of the software, as exemplified in FIGS. 11 to 21, the software will then display interface screen as shown in FIG. 22 to indicate END PROGRAMMING 412, with an additional indicator to show successful end of programming 414 (being a tick), along with an indication that the software has acted to DELETE PAIRING 416, along with additional indicator 418, showing that the software has acted to stop the pairing for communication between the external programming device and the data connection module of the programmable electrical control device 10.

[0105] In a further embodiment (not shown), the data connection module is embodied as a separate device, which is adapted to be plugged in to the power outlet socket of the electrical switching device 12. For convenience, the separate data connection module will be referred to in this description as a dongle.

[0106] In various countries, power outlet sockets are configured with two or more pins or terminals. In Australia, for example, a standard power outlet socket includes three terminals, and most plugs include three corresponding pins for insertion into the three terminals.

[0107] An example implementation of the dongle, in an embodiment of the present invention, includes a single pin for insertion into a respective terminal of an Australian standard power outlet socket. The dongle includes the means for data connection to an external programming device, for example, a USB port, a Wi-Fi® transmitter/receiver or a Bluetooth® transmitter/receiver, using appropriate communication protocols. Further, the dongle may include means for data connection to multiple different external programming devices, using different data communication protocols.

In other optional embodiments, the dongle may have two or more pins/terminals for plugging into two or more respective terminals/pins of the socket.

2018200919 07 Feb 2018 [0108] The dongle may also include an indicator light or other display for showing connection status or other information. A display may also be implemented as an LCD, or similar, display for displaying state or other information.

[0109] One advantage of providing program input via a separate device (dongle) is that the complexity of the programmable electrical control device (or part thereof) situated in the electrical switching device can be substantially reduced. In other words, the programmable electrical control device situated in a power outlet need not include transmission/receiving components for receiving instructions and transmitting state information from/to the external programming device.

[0110] A further advantage of having a separate dongle is that a user could purchase, for example, a number of power outlets with the programmable electrical control device (or part thereof) integrated, but would only need purchase one separate dongle, which could be plugged into the power outlet socket of each power outlet for programming the respective programmable electrical control device as needed.

[0111] Clearly such an optional embodiment would result in reducing the manufacturing complexity of the programmable electrical control device for integration into each power outlet, and would also reduce the cost of manufacturing such a unit.

[0112] The present invention, in embodiments, may be designed so that it is integrated with an electrical switching device, such as a domestic power outlet or light switch. Such a unit may be used when building a new structure, or may be retro-fitted to an existing structure.

[0113] Where the programmable electrical control device, has integrated with, for example, a power outlet, is retro-fitted, the existing power outlet (without a programmable electrical control device) can be removed and the new power outlet with an integrated programmable electrical control device can be wired in to the power supply, and then programmed by the user, using an external programming device.

[0114] Where a separate dongle is provided as the program input, the user may prefer to fit (or retro-fit) a number of power outlets in to a building. In such an example, the user can buy, say, five power outlets with integrated programmable electrical control device and one dongle for programming all of the devices. The user (or electrician) fits the power outlets (each with its integrated programmable electrical control device). When fitted, the dongle can be inserted into the power outlet socket. The user then employs the external programming device to connect to the dongle, and then program the programmable electrical control device with instructions for switching

2018200919 07 Feb 2018 times using the external programming device via the dongle. The dongle is then unplugged from the power outlet socket and inserted into another power outlet socket to program the other power outlet's programmable electrical control device.

[0115] In another embodiment, the dongle may be stored in, or attached to, the body or faceplate of the power outlet. In one alternative embodiment, the power outlet has a cavity in which the dongle can be stored, further including a sprung press release and press store system. The dongle may also be attached to the power outlet via a clipping device. In this way, it is less likely that a user would lose the dongle.

[0116] In accordance with the present invention, the programmable electrical control device 10 is programmable with switching times including at least one supply on period during which the programmable electrical control device is in an on state, such that the electrical switching device is able to supply electrical power when the manual switch is on, and at least one supply off period during which the programmable electrical control device is in an off state, such that the electrical switching device is unable to supply electrical power when the manual switch is either on or off.

[0117] It will be understood by a person skilled in the art that the switching times could include an arbitrary number of supply on period and supply off periods within, for example, a twenty four (24) hour timeframe. Furthermore, it will be understood that the programmable electrical control device may be programmed in such a way as to repeat the same cycle of supply on and supply off periods within a twenty four hour timeframe for an arbitrary number of consecutive days. Moreover, the programmable electrical control device may be programmed to repeat a non-twenty four (24) hour cycle of supply on periods and supply off periods over, for example, a week, or a number of weeks.

[0118] In a further alternative embodiment, the programmable electrical control device may be programmed with instructions for switching times, wherein those switching times are random, or pseudo-random supply on and supply off periods. Of course, the random supply on and supply off periods could be limited to having a minimum time and a maximum time.

[0119] Embodiments of the programmable electrical control device may also include over-ride means. An over-ride would allow the electrical switching device to provide electrical power supply during a supply off period.

[0120] An over-ride may be implemented by using the manual switch of the electrical switching device. In an example scenario, the programmable electrical control device is in a supply off period, the manual switch of the electrical switching device is switched into its off position, in order to over22

2018200919 07 Feb 2018 ride the supply off period, and the manual switch is switched on. The switching on of the manual switch during the supply off period activates the over-ride means, such that the programmable electrical control device is switched to a supply on period and such that the electrical switching device is able to provide electrical power supply.

[0121] The over-ride means, which is activated during a particular supply off period remains activated during that programmed first supply off period, the programmed first supply off period will then change to the next supply on period (during which electrical power supply is programmed to be available through the electrical switching device). At the next programmed change to the supply off period, the electrical power supply is stopped by the programmable electrical control device, whether or not the manual switch is in an on or off position.

[0122] In the present specification, terms have been used which differ slightly from terms used in Australian Provisional Application No. 2012901567, from which the present application claims priority. An example concordance is given as follows:
