Smart switch

All setup for relays should be the same, the change you make between using it with a dumb light and a smart light is to set the switch option to decoupled so that the physical switch only toggles the on/off state of the smart light instead of controlling the connection of the power to the light.

This is why most recommendations are for ones that support this option if you can get them when you can’t find a smart switch that meets your needs for design and function.

Well, thanks both for your replies. Unfortunately this does not bring me any closer to a solution.

I think I will try the Aqara single wall switch no neutral and try to configure it via ZHA. Hopefully it will throw an event which I can track and use in automation.

I will keep you posted!
