I am currently looking for a heatpump for my house and one important point for me is that i can control it via openhab.
I have some similar usecases in mind. As it will likely be an air source heat pump I want to be able to perform some noise reducing actions at specific points in time. Therefore I need to switch on/off the heat pump or limit the power. Is this for example possible with the tag COMPRESSOR_POWER? Or is this just a read tag?
You can enable the waterkotte heatpump or disable, but this heatingpump cannot modulate its power. In the settings there is some place to change the power, but i don´t know which model of waterkotte can do this. My one can´t do it, it has only one power setting with 100% (6kW thermal output).
If i would buy a new one, i would buy a nibe heatingpump - there is a new model which can modulate its power and the heating pump control is like a dream. But i don´t know about air heating pump, i have a brine collector.
There will be a new version of ecotouch binding soon. There you can control the photovoltaik-sensor.
So you can send a command to the heatingpump with openhab, when there is much power from your photovoltaic to start heating with higher temperature. Or you can build your own switch to simply switch on warm water production.
I will get a test version from the developer the next few days.
Did you get any update from them? It seems that the waterkotte binding is not under further development.
Nevertheless i created an example that works with indirekt connection of photovoltaik and heating system:
Hi guys, if someone is willing and able to work on that binding i would like to support.
