My heat pump, streaming live data...
http://open.sen.se/ashp_tsh

On the 2nd tab (pump), I have flow and return temperatures, and am inferring heat flow based on 0.5m3/hour (which is correct give or take 10%). From this I am calculating COP in real time, and also integrating the performance by resetting the counters every time the pump starts up. When the circulation pump is running but the ASHP is not, this results in heat being lost, so for a short input burn, the efficiency for that cycle is small (but the energy is also small).

I am also calculating real-time daily performance in terms of kWh/degree-days (as a % of 20kWh for a 10 degree.day day)
