I am trying to install a few recessed led lights that are dimmable. To automate them, I want to add a smart WiFi relay that is able to dim them as well as turn them on/off. I seem to find either dimmer relays or switches that work with external dimmers. I can’t seem to find them both functionality in one.
Maybe it’s different in the US but here in Europe I have trouble finding a mains-powered rotary knob, they all come with an internal dimmer, like this one, which I believe is what you want?
