Request Manual COP calculation (using own kWh device) #30

Open Maarten69 opened 2 years ago

Maarten69 commented 2 years ago

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!

Item is too complex There are variations to take into acccount.

power measurement via 1wire connection. Other sources.

There can be separate power measuermeent for ellectrical heating unit, or the panasonic compressor. Sometimes these values need to be added to eachother.

These variations, together with the GUI, together with the logic, resulted in me hanging for a long time in development. I will not persue this matter further. I have taken the work I have done out of the flow.
