Yeah, I agree. I built a android based therm thing way back in probably 2013-ish (based on a OSS project that probably no longer exists).
No matter what I did it was buggy as fuck. The hardware(and software) monitoring never worked right no matter how I tweaked it. I went back to a dumb therm since I didn't like waking up with the furnace turned off in -20F because the damn thing wasn't working right.
At least I was still using my wood burning stove back then (I miss that house and the stove) so it's not like everything was frosty but it was cold since most of the logs died down. I put a few more logs in, went back to bed and when I woke up the next day the first thing I did was rip that thing off the wall and replace it with a simple but reliable programable therm.
