I have a heat pump, but two factors has made me want to let HA get control of it:
- The heat pump thermostat is really quite poor, and will result in wildly varying indoor temperatures.
- Partly due to this, my wife handles the remote a lot, and tends to overcorrect somewhat… (Hello Antarctica!)
So I did a bit of research and found this library:
His libraries work with ESPEasy, and since I had a NodeMCU lying about, I managed to get that working with HA, connected a BME280 temp/humidity/pressure sensor, and a transistor-activated IR LED.
To go with HA’s newfound control of my heatpump, I made a manual control panel for it, and an automation that adjusts the heatpump settings to attain the desired living room temperature.
PS: Sorry for the norwegian everywhere, I couldn’t be bothered to translate it, but I think the automations should explain it if you are trying to do something similar:)
The results aren’t perfect, but it’s a lot better than I’m used to:)
(It’s been running since about 14:00 in this graph.)
One of the main reasons it fluctuates a bit is that I’m only letting it change settings every 5 minutes, mostly to prevent the heat pump from being too annyoing as it goes beep every time it receives a command.
My config looks like this:
