Give your existing lights smart functions such as remote switches, programming and voice control (in combination with Google Assistant or Amazon Alexa), just by installing this smart switch module with Wi-Fi. Connect it to Nedi's free SmartLife app with nothing but your Wi-Fi and turn your traditional lights into smart lighting while still being able to use your existing switches to turn the lights on and off.The compact size (41x41x20 mm) allows it to be installed in the existing switch cabinet, behind any cabinet or above a suspended ceiling.Note! Neutral wire is required to power the module.Combine this switch module with other smart products in the Nedis SmartLife app to create scenes or automations, such as turning on the light if motion is detected or lowering the blinds when you turns on the lights in the evening.Schedule the lights to turn on and off based on your presence, at sunset, or at precise times, not only to make your life easier, but also to simulate that you is at home when you are actually somewhere else.
