Hamilton have released an interesting new smart rotary dimmer that also has a intermediate module so you can have multiple rotary dimmers controlling the same circuit as well as Smart Control.

The big downside is lack of obvious public API. Is Alexa and Google home compatible so should be possible. I’ve emailed them to ask about any API documentation.
It’s WiFi so shouldn’t be hard I’m hoping to work out as long as no encryption involved.
This will be huge in my house to going back to rotary dimmers rather than momentary switches.
