Which one of your sensors or input_texts has an unknown state?

Look in Developer Tools → States.

You can ignore everything except sensors without a unit_of_measurement. i.e. only consider text based sensors.

Also you should not have that many unknown devices in your config.

I disabled or edited all of this sensors, and problem is solve!
Thanks!
