Where can I find Total Electricity and Total Heat output values (for SCOP calc)?

Hi all,

I am trying to setup a dashboard in HA for my heat pump, which is almost done.

One last thing that I don’t seem to be able to figure out is how to get the values of
“Total Electricity input” and “Total Heat output” as they are displayed on emoncms and are used to calculate the SCOP.

Any idea how these are calculated on the dashboard?

I have found that currently Total electricity is about 30kWh off (from the feed used ( heatpump_elec_kwh)) and Total heat is about 170kWh off (from the feed used ( heatpump_heat_kwh) ).

Why is there a difference between the value displayed and the value in the feed?
I tried to create a new app and initially the values of Total electricity matched with the feed (( heatpump_heat_kwh) ) but after a few minutes it settled back to the one which is 170kWh less.

I have Level 3 Heat Pump Monitoring Bundle(emonHP)

Cheers,
Zen

If your system is published on heatpumpmonitor.org you can use the HPM API to get lots of stats including COP: https://heatpumpmonitor.org/api-helper

Ah I checked the API for emoncms but completely forgot the heatpumpmonitor.

Many thanks, will have a look :smiley:
