Request Manual COP calculation (using own kWh device)

[Maarten69]

I would like a better COP calculation while the built in one is way to optimistic. I have one kWh device that measures all consumed power from Heatpump. This one: DDS353 https://www.elektramat.nl/emat-kwh-meter-45a-1-fase-digitaal-mid-ematkwh1f32dmid/

Example script to use I found are (from Tweakers.net): https://github.com/Dylantje/WP/blob/main/COP%20include%20Defrost and https://github.com/Dylantje/WP-Heishamon-sripts/blob/master/WP%20LUA%20COP%20en%20Verbruik

Thanks in advance!
