I've just noticed the following behaviour on the heatpumpmonitor and I was wondering if someone could tell me if it's normal:

You can also see it here https://emoncms.org/app/view?name=MyHeatpump&readkey=b3a7b99ad8fc6d53a53fd4182026dd92

 

I know heat pumps try to modulate so maybe it's just that just looks a bit weird on the monitoring the constant fluctuation of COP and flow temp

@wawyed  Mine isnt doing that, is your water pump PWM controlled?

Yes, I believe it is. The flow rate seems to change on the monitoring.

 

EDIT: Just checked it's a Grundfos UPM4

@wawyed Thats the only thing I could think of that might account for the difference. It looks odd but I doubt its affecting COP much
