Did you see my post just above? Switch that device to "Room Lights Activator", instead of "Room Lights Activator Bulb". Fix for this in next release.
I did. Nice to see you are adding the button property.
Dashboards for Scenes
How do I set the dashboard to use a button type for an activator? I changed the type from the default color bulb to button 1 press, but it does not work. If I set it to a switch, the behaviour is stateful. If I activate family bright(on) then family dark(on), then family bright(off) all the lights are turned off. Should the default for an automation activator not be a button?
What you've shown in the screenshot has a tile for Family Bright as button. This works for me. Please show logs of it not working, for either Room Lights or the Activation Device itself.
