Scores calculated for each light switch 1000 based on the results are schematically shown.

As shown in FIGS. 2 and 3 , the home gateway 2000 communicates with each of the plurality of light switches 1000 in a predetermined first cycle to obtain an RSSI value and response time for each light switch 1000. A network connection state determining step (S120) of determining a network connection state including; And after calculating the score for each lighting switch 1000 based on the performance result including the RSSI value and the response time of the network connection state determination step (S120), the score among the lighting switches 1000 is preset One or more lighting switches 1000 belonging to the first section are selected as the fixed relay switches 1100, and one or more lighting switches 1000 belonging to the second section preset to have a lower score than the first section are selected as fixed relay switches 1100. The lighting switch 1000 is selected as the general lighting switch 1200, and one or more lighting switches 1000 belonging to a third section in which the score is set lower than the second section among the lighting switches 1000 are relayed. After the fixed relay switch selection step (S130), which is selected as the required switch 1300, and the fixed relay switch selection step (S130), the home gateway 2000 is configured to include the relay required switch 1300 and the fixed relay switch.

Specifically, as described in the description of FIG. ) can be selected. To this end, the home gateway 2000 performs the steps shown in FIG. 2 by communicating with all the light switches 1000 in the residential area as shown in FIG. 1 (a).

First, the home gateway 2000 performs a connection state check request step (S100) of checking the connection state to each of the plurality of light switches 1000. The light switch 1000 may generate a response signal in response to the connection state confirmation request received from the home gateway 2000, and the light switch 1000 transmits the response signal to the home gateway 2000. To perform the response signal transmission step (S110).

The fixed relay switch The process of pairing between 1100 and the relay required switch 1300 will be described later in the description of FIG. 4 .

On the other hand, in FIG. 3, even if the total score is the lighting switch 1000 belonging to the first section, if at least one section corresponding to 0 points exists, such as the score of the lighting switch # 12 during the section corresponding to T3, the corresponding lighting The switch 1000 is not selected as the fixed relay switch 1100. That is, when the sum of the points of the lighting switches 1000 recording even one 0 point belongs to the first section, the corresponding lighting switch 1000 is selected as the general lighting switch 1200, however, even one recording 0 points When the total score of the lighting switch 1000 belongs to the second section, it is selected as the general lighting switch 1200.

Assuming that the brightness of the lighting that can be controlled by the light switch 1000 is, for example, 0 to 100%, the nursing light service is completely turned off at night or stays at 1 to 2% brightness, , If there is movement, it is slightly brightened by 3 ~ 5% for a certain period of time so that the mother can comfortably breastfeed with the help of automatic lighting control without additional manipulation, or when the elderly and children go to the bathroom at night. This is a service that wants to help. Since PWM control can adjust the brightness of lighting from thousands to tens of thousands, it can also provide lighting brightness that suits the user's taste.

The security service makes the ceiling light blink when illegal intrusion is detected through the motion sensor module included in the light switch 1000 so that the state of intrusion can be suspected from outside, and through a dedicated application of the user terminal 4000 This is a service that can send an alarm message.

The lighting mode that can be stored according to the user's input may be a lighting mode for each color temperature of the lighting controlled by the color temperature controller 3120 or a lighting mode according to the brightness of the lighting controlled by the brightness controller 3110. can

For example, if the user stores the lighting with 70% brightness as the first lighting mode, the user can turn on the lighting by selecting the stored first lighting mode without needing to control the brightness of the lighting at 70% again. can In addition to the brightness of the light, for example, if the light with a color temperature of 3000K is stored as the second lighting mode, you can turn on the light by selecting the stored second lighting mode without needing to control the color temperature of the light with a color temperature of 3000K again. can In this way, the user can input the storage of the desired lighting mode for the brightness and color temperature of all lights that can be controlled by the light switch 1000, and the lighting mode storage unit 3130 receives the user's input. It can receive and save the lighting mode.
