    @gavin57 @CaffeinatedBookDragon @cstross @Oggie @pluralistic Thing about a dumb wired thermostat is that you can't turn the temperature up remotely a day or two before you return home.

    I've wired a smart relay in parallel with the dumb thermostat so that I can do that. We'll see if it works in a couple of weeks.

      @tokensane @gavin57 @CaffeinatedBookDragon @cstross @Oggie @pluralistic My dumb thermostat has a prediction feature! - there's a resistor in it which heats up faster than the radiator and turns the heating off before the radiators overheat. Unbelievably crude, but they've been making the same device for several decades so someone must think it works.

      This resistor is however the reason that someone bothered to run a neutral wire to the thermostat, so there was a neutral available where I tapped into the cable, which is good because the smart relay needs a neutral.

      I'm controlling the smart relay with a #HomeAssistant virtual thermostat run from a temperature sensor in the living room (as compared to the dumb thermostat which is in the hall, which we have no particular desire to heat). Left to itself it keeps the temperature to within 0.1°C. But it's not always left to itself, eg if the cooker is on the temperature overshoots.

      @TimWardCam @gavin57 @CaffeinatedBookDragon @cstross @Oggie @pluralistic The other thing about dumb thermostats is that they have hysteresis and no prediction. Say you set it at 20 degrees C. It waits until the temp is 19 before turning on. Then it stays on until the temp is 21. But the radiators are still hot so your house heats up to around 22. A 3 degree temperature swing is pretty uncomfortable.

      Our smart thermostat now keeps the temp within 1/2 a degree C of what we set.

      @TimWardCam @rotopenguin @tokensane @gavin57 @CaffeinatedBookDragon @Oggie @pluralistic We increasingly do need a/c, but here in Edinburgh it's still for maybe one week a year. London and parts south are getting a bit muggy in summer these days, though.

      @TimWardCam @tokensane @gavin57 @CaffeinatedBookDragon @cstross @Oggie @pluralistic now, if only thermostats also had a "cold anticipator" for the summertime.

      @rotopenguin @tokensane @gavin57 @CaffeinatedBookDragon @cstross @Oggie @pluralistic Not a problem in the UK - we don't need AC.
