Some firmware to be shared, nothing special just sharing in case someone else wants to start monitoring heatpump systems for COP monitoring.
1) EmonTX Air-to-air heatpump monitoring with RPM detection and 1-wire sensors in airflow to calculate output
2) EmonTX Air-to-water heatpump monitoring with 1-wire sensors attached to both sides of heat exhanger to calculate output. This is constant waterflow system. Same emontx is used for monitoring the water heater and electric heating system of the house.
3) EmonTX general 3 phase measurement with voltage
4) EmonGLCD that monitors and displays of COP of the full heating system. The 1-wire on the display is placed outdoors to calculate heating need of the house that is then compared to the heating output.
5) Funky sensor firmware
6) NanodeRF, known to work multinode.no hangups or anything.
emoncms.org for the house monitoring is currently the following, this display shows heating input, output and calculated heating need:

Re: PetriK - Emon project files for share, e.g. heat pump with COP calculation monitoring
Nice display Petrik.
I can see why you need to monitor your energy use, a chilly -11C when I looked this morning.
It's a toasty +9C here in the UK midlands and lots of Solar PV this morning

Wow thats a really nice set of dashboards! nice work and thanks for sharing the code
