Thermostatic valves should be moved from time to time so that they don’t get stuck. As I only use electronic thermostatic valves, I have written an automation system that detects all the thermostats and then turns them fully open once, closes them completely and sets them back to the previously set temperature. So we need … Read more
Unfortunately, the Lambda heat pump only passes on the total amount of energy consumed via the modbus interface. It would be interesting to know how many kWh are required for heating and how many kWh for hot water. As the Lambda passes on the total consumption via a Modbus register “hp1_compressor_power_consumption_accumulated” and the status via … Read more
After using a fairly simple solution in the first post on the subject, I now have a sensor in use that automatically detects when the window is open and then turns the heating down. This completely automates the control system. I took my very simple door/window sensor and integrated it into my Home Assistant. This … Read more
After I was quite happy with my smart heating control system, my partner asked me what I should do when I open the window in the bathroom after showering. Since I still had a Sonoff Button lying around, I put it on the window in the bathroom and wrote two automations that take over the … Read more
Here is part two of my journey to smart heating control. First of all, I created some helpers: The selection of the scene then controls the heating control sequence.E.g. Tue & Thu in Cologne, then everything goes to day temperature at 6:00am, but Tue & Thu the heating switches to night temperature during office hours … Read more

I already had Comet Dect radiator thermostats from my old apartment, which I could control via the Fritzbox. These are replicas of … Read more
