This made me think:

What about thermal runaway protection? I'm betting that might be easily overlooked in a custom "smart device" if, for whatever reason, the temperature sensor were to fail and keep reporting "Hey it's still only (below_target_F_degrees) in here! Keep that heat on full blast!"

This was an issue that made jank 3D printers catch fire and burn houses down until it was mitigated with open source firmware.

Point being, unless there's a "custom smart thermostat project" that's vetted and trusted, stuff like this might be overlooked in someone's Python project, wherein it's bog standard, low level, possibly redundant, in consumer devices. (Especially thanks to safety standards.)

Should there be an open-source smart thermostat project that's looked over by thousands of HVAC turbo-nerds and engineers? Yes. Yes there should! Might already be?
