Ive set to LWT control with a curve of 48@-5 and 30@14
From what I can see on heatpumpmonitor.org the power draw should be fairly consistent but I can hear the compressor ramping up and down constantly in these cooler temperatures, my electricity usage looks very different to anything I’ve seen.
I know I have a few defrosts in there but is there something wrong here?
i have the same heatpump if you want to compare , but there are a lot of variables

It’s strange, this behaviour only seems to show under LWT control only, if you use Madoka control, even with no modulation, the power usage is quite different!
Can anyone explain why?
You need a few more data points to make an assessment, I guess the power graph is from Home Assistant, if you do not have an espaltherma setup, try the web API via HACS as a starter -
Then compare the power graph with the corresponding LWT, I noted a few problems when the system was ‘balanced’ too much, so I opened the lockshields completely and allowed more flow, with the espaltherma you can see a lot more data inc l/min, calculate DT/COP etc
espaltherma (near real-time)-
check out -
I have an ESP ready to plug in, but I’m a bit anxious about taking the cover off!
Taking the cover off is easy, getting it back on is the hard part…
