The switch is compatible with voice speakers such as Amazon ECHO, Google Home, and others. You could use your voice to control the switch’s status.

With this Wifi Smart Light Touch Switch 3Gang, you can turn on or off the light by opening or closing the relay contacts (neutral wire required). It can be used to control smart lighting systems in homes, hotels, offices, and other commercial spaces.
