Smart home technologies are on everyone's lips and there are now many ways in which existing households can be retrofitted. One of the many variants is the WLAN light switch. It enables permanently installed electrics to be easily controlled via an app. More and more models are also compatible with Amazon Alexa and Google Home, in some cases up to 3 devices can be connected to a Wi-Fi switch.
Wi-Fi light switch as a smart home system
The functionality of Smart Home light switches is similar to WLAN sockets. Existing devices in the household that cannot be controlled via app are connected to the Smart Home system and can therefore also be controlled while on the move. The intelligent light switches make it possible to retrofit your home quickly at relatively low cost.
The Smart Home light switches are connected to the flush-mounted sockets instead of the usual light switches. In the case of electrical installations of this type, it is generally recommended to consult a qualified electrician. It is important that the voltage is removed from the line before starting the retrofitting. The Wi-Fi switch must be connected to the neutral conductor and the outer conductor, which must be screwed tight as usual. In order to be able to install the intelligent light switch in the flush-mounted installation, it is helpful if it is the right size when buying it. With the appropriate diameter, the Wi-Fi light switch is quickly built into the cavity wall socket and the smart home socket is networked.
