    Our smart thermostat has never been all that useful to me. The main thing is I don’t have to walk over to it to change the temp. But that convenience isn’t really worth the $150 I paid for it.

      The idea is that you can use peaks and drops in electricity pricing to optimize the usage and also to lower the house temperature when nobody is home and raise it again when an occupant enters maybe a 1km radius around the place again.

      The way you’re using it is just a gimmick, that’s true.

          No, my point is: using it as I described really saves money. The effective power price for my heat pump over the last year is at about 20% beneath market average because I use the thermal mass of my floors to store energy during low price hours. That needs to run automatically, controlling that by hand would be massively annoying or not possible at all when I’m not home.

          In addition, when one of our cars is started at one of our respective work carparks the hot water supply is checked and gets heated if it is below the necessary temperature for a shower. So either the day brought enough solar energy that it’s hot enough anyway or the water is heated very specifically for the after work shower for a person returning home. That prevents the heat pump from having to keep high temperatures all day in winter.

          The blinds follow the sun when the room temperatures pass 22°C and the solar panels deliver more than 2kW, because in that case it’s obviously sunny. Saves a lot of energy for the AC.

          All that saves way more than 100€/year, so remotely controllable fixtures stop being just a gadget when you start to think about the whole energy management in your house, is my point.

            using it as I described really saves money

            Assuming I:

            • own a heat pump ❌
            • own solar panels ❌
            • own a smart water heater of some kind? ❌
            • live somewhere that the temp changes enough that any of this matters ❌

            “No you idiot, you just have to spends thousands of dollars on equipment and then you can save $100 a year”

            Do you realize how ridiculous you sound? Good for you that you’re saving money, but I’m just giving a personal anecdote here, not writing a thesis on home energy management.

              You don’t need solar panels. Could also just be dynamic energy pricing. Also do not need a water heater. Thermal mass could just be heating the place at a certain time. Don’t get the bit about temp changes, maybe you mean you never heat or cool your place?
