I have a Stiebel Eltron heat pump being installed in a couple of weeks time, and am looking at how I can integrate it with my existing EmonCMS deployment. I had originally planned to get a Heat Meter installed, however I am wondering if I can just use the data from the Stiebel ISG gateway instead?
The ISG provides running daily & totals for heating & cooling in kWh, along with the flow temperatures. The only item that it doesn’t seem to provide is a current output value for heatpump_heat. Is that required though, if heatpump_heat_kwh is provided? Would EmonCMS still be able to calculate CoP?
There’s a demo of the ISG here: STIEBEL ELTRON Reglersteuerung
Thanks in advance!
