Non-updateable Input_Number

Of course it’s debatable: I expressed an opinion (“I think”), yet you only take on one of the people that used the word simplest. I also used “or” to express it as another alternative, not the only option.

I maintain what I said, because I worked from the fact that they already had other parts working, and while perhaps not optimal (to your point), they wouldn’t need to change anything. That makes it simple in my view (which is different to some definition of “best” or most efficient, which I didn’t claim). The tap action is also relatively simple, being an.option on the same card I referred to.

I do use History Stats and Utility elsewhere, but for this boiler project I have the ESP device itself keeping track of runtime_today, and displaying it on its own screen. So apart from the reboot problem, it should make the HA automations/templates simpler. I’m actually tying myself up in knots with all the old automations from the previous simpler boiler monitor I had. I’ve got loads of entities I need to delete, but keeping track of them; well…does my head in!
