    Those are all very nice things to have in an improved thermostat, I agree completely

    The point I was replying to was making the erroneous claim that basic operation of an HVAC isn’t possible with an RPI thermostat because of things the thermostat doesn’t handle

      I think what you’re failing to understand is that newer HVAC units are designed to be run in a specific way. if you disregard that, and run it like a unit from the 1980s you will halve the life of the unit.

      yes, most of the “brains” are on the unit itself but without proper “eyes” the brains are useless.

      I’m not even an HVAC tech but I’ve worked on them enough to know it’s a dumb idea to just replace your thermostat with “a raspberry pi and a bunch of 24v relays”. there’s just too much risk of things to go terribly wrong and multiple people literally die.

        Not missing that, as I and yourself said it’s done via the actual HVAC unit and not the thermostat

        but without proper “eyes” the brains are useless.

        No, the nicer features just don’t get used, it doesn’t make the entire unit not work

        there’s just too much risk of things to go terribly wrong and multiple people literally die.

        Lol, people aren’t going to die if you replace your thermostat with an RPI unless you wired the thermostat so poorly that you somehow manage to schock someone touching the thermostat

        Again: thermostats just tell the HVAC to run and which part to run, any other advanced features are not required to be catered to in order to work. My brand new fancy schmancy heat pump with all those cool features listed runs off the same $2 Honeywell thermostat my old heater did, if I want the advanced features like zone sensing I can upgrade my thermostat, but my heat pump works without them just fine
