Seems like a dumb question. I’ve looked through many apps, most of which will do what I want but in a non-optimal way. The switches in question are dimmers.
I tried SmartLighting first, but I have to make two rules, and if I reboot my hub sometimes the two automations will get into a looping condition.
I see scene apps, a Dim with Me app that seems out of date, ones that will sync virtual with physical, and the Trend one that is more power and virtual than I want. I just want two switches to mirror each other, no matter what happens to one, it should happen to the other.
What are you all using right now? Prefer local execution, but thinking I have to move to an app. Prefer github integration, and something that is maintained.
