I have edited the OP to include a disclaimer about the usage of Dimmers with this app. Please bear in mind that the way Dimmers report “off” events, they may toggle your slave lights (unexpectedly) in the following scenarios:
- Master switch is on and you turn it off
- You dim the master swtich to 0 using an app
I have thought about ways I can try to account for this, and, based on feedback I have received from other developers, have decided trying to “fix” this may cause more problems than it solves. I think dimmers are still totally usable day-to-day with this app, just as long as you understand these things may occur. “On” never seems to be a problem.
