I have a rule that "Nothing will be automated that cannot be manually overridden."
Well, actually it's my wife's rule but it's a good rule nonetheless. As a result, there's a big panel full of relays in the basement that is the "last mile" for anything climate control or security related.
There have been a few times when it's been handy. Like when the exhaust fan isn't working and I don't want to debug the ESP32 controller today so I just flip it over to "Manual".
