I had bought myself a long time ago already a twilight sensor (transmitter) and the appropriate versions. To ensure that our input light will be switched automatically. After purchasing the socket sets I could assign the outlets as described the transmitter switches. Connecting I wanted to couple with the twilight switch switches. This went on: 1. Set button of the twilight switch, press a few seconds until the sensor starts flashing. 2. Now just plug a wireless socket into the wall outlet. - The receiver is synchronized and switched three times briefly on and off. 3. Done. The wireless socket is now switched on and off by the twilight switch and can also be controlled by the remote control.
