So when you say AC fails, are you talking about home assistant restarting, the esphome device restarting, or both.

when the esphome device restarts, on te home assistant I have an UPS

I think use a variable in home assistant to keep the current setting, and set the esphome via an on_boot setting.

I have no idea how to do it. Can you help me?
