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.
