2 function switch for ceiling fan and light?

The Zooz dual switch is intended for a single speed extractor fan, like you would find in a bathroom.

The Inovelli switch is intended for a multi speed fan, but as of this writing has not yet started shipping.

If your fan is instead a typical multispeed low/med/high ceiling fan then see the following FAQ. (It says Alexa in the thread title, but it applies whether you were using a voice assistant or not.) :sunglasses:
