Detailed description of embodiments In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular architectures, interfaces, techniques, etc. in order to provide a thorough understanding. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description with unnecessary detail. Same reference numerals refer to same or similar elements throughout the

description .

Briefly, the present disclosure provides, in an aspect, an

electricity meter comprising a communication interface towards a product manufactured by an Original Equipment Manufacturer (OEM) . The communication interface enables the electricity meter to communicate with an OEM device of the product. The electricity meter further comprises a communication interface towards a gateway. The electricity meter may thereby act as a communication node for an OEM product that comprises the OEM device, besides its functions as an electricity measuring and/or electricity consumption predicting device. The Original Equipment Manufacturer (OEM) is thereby enabled to communicate with the OEM product via the electricity meter and the gateway. The OEM can make great cost savings in that no additional investment costs are needed for communication to external devices such as routers and gateways.

Figure 1 illustrates an environment wherein aspects of the present disclosure may be implemented. In particular, the figure illustrates a product 3, exemplified by a washing machine. In the following, a manufacturer of a product is denoted Original Equipment Manufacturer (OEM) , and the product 3 that the OEM manufactures is denoted OEM product 3. It is noted that the OEM product 3 may be any appliance, for example a home appliance such as a refrigerator, a washing machine, a tumble drier or a dishwasher.

The OEM product 3 comprises an OEM device 4, in turn comprising logic for collecting and storing information about the OEM product 3. Such logic may comprise e.g. a printed circuit board (PCB) , processing unit, software, hardware, electronics or any combination thereof. The OEM device 4 is thus configured to collect data about the OEM product 3. Such data may for example comprise error codes by means of which the OEM, receiving the information, may perform trouble shooting of the OEM product 3, and/or data about the OEM product 3 such as water temperature of a washing machine and/or warning messages such as load of a tumbler dryer being too large. In short, the OEM device 4 may retrieve or receive and store any data that is specific for the OEM product 3 in which it is installed.

Figure 1 further illustrates an electricity meter 1, in the figure being embedded within the OEM product 3. The electricity meter 1 comprises means 9 for measuring or reading electricity data e.g. electrical energy consumption of the OEM product 3. Such means 9, schematically illustrated at reference numeral 9, may comprise a measuring device, such as a current measuring device, and/or a voltage measuring device and/or a processing unit configured to calculate the energy consumption based on the measurements. Such measuring device (s) may be arranged at an electricity supply of the OEM product 3. The electricity meter 1 is configured to send corresponding measurement reports to e.g. an OEM or to an

electricity supplier using a first communication interface 6. The electricity meter 1 may also be configured to predict electrical energy consumption of the product 3, e.g. based on the measurements.

The electricity meter 1 thus further comprises the communication interface 6 enabling communication with a gateway 2, which comprises a corresponding communication interface 15. The communication interface 6, 15 may for example comprise a ZigBee communication protocol, a communication protocol for a Wireless Local Area Network (WLAN) , an Infrared (IR) communication interface using any

communication protocol, or a Bluetooth communication interface or any other wireless or wired communication interface. Short-range communication protocols are often sufficient in case the

communication is wireless. The communication may be wired or wireless and the communication interface may consequently be a communication interface using a wide range of different

communication protocols for wired or wireless communication. The electricity meter 1 further comprises a processing unit 10 (see figures 2 and 3), e.g. a central processing unit, microcontroller, digital signal processor (DSP), etc., capable of executing software instructions or code of a computer program stored in a computer program product e.g. in the form of a memory.

The electricity meter 1 further comprises a second communication interface 5 for communication with the OEM device 4 of the OEM product 3. If the first communication interface 6 and the second communication interface 5 are of the same type, the electricity meter 1 need only comprise a single communication interface by means of which it communicates both with the gateway 2 as well as with the OEM device 4.

The gateway 2 is connected to or is able to communicate with one or more such electricity meters 1. The gateway 2 and the electricity meter 1 together create a transparent peer to peer communication link 12, 13, 14 between the OEM and the OEM product 3. That is, the communication link 14 between the OEM device 4 and the electricity meter 1, the communication link 13 between the electricity meter 1 and the gateway 2 and the communication link 12 between the gateway and the OEM together provides the peer to peer communication link. The communication link 13 between the electricity meter 1 and the gateway 2 may for example comprise a link of a Local Area Network

(LAN) . The gateway 2 may route data to a communication network 11, e.g. a Wide Area Network (WAN) , from which the data is available to the OEM for e.g. analysis and billing purposes. The gateway 2 comprises an interface (not illustrated) conveying the data to the communication network 11, and such interface may for example comprise an interface for Ethernet, General packet radio service

(GPRS) , KNX, LonWorks (local operation network) TP/FT, profibus, DL/T 645 etc. The OEM having access to e.g. a laptop 8 may thereby remotely retrieve and send data from/to the OEM product 3. The OEM may then in turn make such data available for the owner of the OEM product 3, for example via a website, via a mobile phone etc.

The OEM may connect to the gateway 2 using different types of communication ports, for example a serial connection, an Universal Serial Bus (USB) connection, Transmission Control Protocol/ User Datagram Protocol (TCP/UDP) ports via Ethernet etc. The

communication network 11 over which the OEM communicates with the OEM product 3, via the gateway 2 and electricity meter 1, may thus use different types of communication interfaces.

As an example of a particular usage case, the gateway 2 may be located in a multistory building comprising a number of apartments. Each apartment may comprise one or more OEM products 3 comprising or being connected to one or a respective electricity meters 1. The electricity meters 1 can communicate with the gateway 2 over the communication interface 6, and the gateway 2 routes data to/from the OEM over the communication network 11.

Figure 2 illustrates a first set-up of the electricity meter 1. In this embodiment, the OEM device 4 is located within the OEM product 3, i.e. the OEM product 3 comprises the OEM device 4. The

electricity meter 1 is also embedded within the OEM product 3. As described earlier, the electricity meter 1 comprises a first communication interface 6 by means of which is can communicate with the gateway 2. The electricity meter 1 further comprises a second communication interface 5 by means of which it can communicate with the OEM device 4 of the OEM product 3. As noted earlier, if the first communication interface 6 and the second communication interface 5 are of the same type, the electricity meter 1 need only comprise one single communication interface (not disclosed) by means of which to communicate both with the gateway 2 as well as with the OEM device 4.

It is noted that the OEM device 4 and the electricity meter 1 may be integrated into a single module. The OEM product 3 integrating the electricity meter 1 can thus utilize the first and second

communication interfaces 5, 6 of the electricity meter 1 to communicate with the OEM via the gateway 2.

Figure 3 illustrates a second set-up of the electricity meter 1. The OEM device 4 is again located within the OEM product 3, while the electricity meter 1 is located outside the OEM product 3, preferably in the vicinity of the OEM product 3. The electricity meter 1 is thus in this scenario a standalone device connectable to the OEM product 3. The electricity meter 1 may be connected to the OEM device 3 in a wired or wireless fashion. The electricity meter 1 could be configured to act as a communication node for more than one OEM product 3, however in a preferred embodiment each OEM product 3 comprises or is connected to its own electricity meter 1.

Irrespective of whether the electricity meter 1 is housed within the OEM product 3 or not, the communication link 14 between the electricity meter 1 (possibly embedded) and the OEM device 4 may utilize a communication interface such as e.g. an Universal

Asynchronous Receiver/Transmitter (UART), Serial Peripheral

Interface Bus (SPI) which is a synchronous serial data link standard operating in full duplex mode, I2C bus or the like.

The electricity meter 1, e.g. the processing unit 10 thereof, is configured to recognize communication traffic, i.e. data packets, intended for the OEM product 3. The electricity meter 1 may be configured to recognize such data packets e.g. by means of a specified traffic indicator of a header of the data packet or by means of some kind of identification of the data packets. Upon recognizing such communication traffic, received from the gateway 2 and originating from the OEM, the electricity meter 1 is configured to forward the communication traffic to the OEM device 4, and in particular the logic therein. The electricity meter 1 need not open the data packets but simply forwards them. The data packets are then handled by the logic of the OEM device 4. The electricity meter 1, e.g. the processing unit 10 thereof, is also configured to convey data packets from the OEM device 4 to the OEM in a corresponding way, i.e. receive the data packets from the OEM device 2, and forward them to the gateway 2 for further conveyance by the gateway 2 to a system accessed by the OEM.

The gateway 2 may be configured to handle access rights of a user, e.g. the OEM, trying to communicate with the OEM product 3, e.g. by requiring identification of the user. Such identification may comprise e.g. entering passwords or other authentication means. The OEM may, by using embodiments of the present disclosure, use the communication interface 6 of the electricity meter 1 to communicate with their OEM product 3, and the need for adding an additional communication adapter to obtain the possibility to interact with the OEM product is omitted. As mentioned in the background section, this communication interface 6 is, in prior art, primarily used to read out measurement values and to configure the electricity meter 1. In aspects of the present disclosure thus, the electricity meter 1 is used also as a communication node for the OEM product 3.

In an aspect, and with reference to figure 4, the present disclosure provides a method 20 performed in the electricity meter 1 as described. The method 20 enables conveyance of product specific data to the OEM by means of the electricity meter 1. The method 20 comprises receiving 21 a data packet comprising OEM product 3 specific data. This data packet is received from the gateway 2.

The method 20 further comprises identifying 22 the data packet to be intended for the OEM product 3. This identification, or recognition, may be done as described earlier, e.g. by means of an indicator of the data packet, e.g. in the header of the data packet.

The method 20 further comprises forwarding 23 the data packet to the OEM device 4 of the OEM product 3 by means of the communication interface 5 of the electricity meter 1. The communication interface 5 is, as described earlier, configured to exchange data with the OEM device 4 of the product 3.

It is noted that the electricity meter 1 may also convey data packets from the OEM device 4 to the gateway 2 in a corresponding way. The method 20 may thus comprise performing the steps for conveying data packets in the opposite direction (from OEM device 4, via the electricity meter 1 to the gateway 2 and further to the OEM) .

With reference again to figures 2 and 3, the present disclosure also encompasses a computer program 16 for conveying product specific data in accordance with the method 20. The computer program 16 comprises computer program code which when run on the electricity meter 1, and in particular the processing unit 10 thereof, causes the electricity meter 1 to perform the method 20 as described.

A computer program product 17 is also provided comprising the computer program 16 and computer readable means on which the computer program 16 is stored. The computer program product 17 may be any combination of read and write memory (RAM) or read only memory (ROM) . The computer program product 17 may also comprise persistent storage, which, for example can be any single one or combination of magnetic memory, optical memory, or solid state memory .
