I agree, that would be good to add. That’s a commonly requested feature

Nice graphs! However, as a 9kW Daikin Altherma owner, the 100W threshold is too low - my circulation pump pulls 180W (!) just checking the current return flow temperature between cycles, prior to triggering the compressor when it’s dropped low enough. A compressor cycle runs at 800+W minimum! I realise that for many that’s too high, but perhaps it could be configured?

Perhaps the threshold can be raised to 200W globably? I can’t imagine that there’s any domestic heat pump that modulate down to 200W?
What are you using to measure the power used by your pump? I would be very surprised if a domestic circulator pump was using 180W. What’s the make and model of your circulator pump?
Also, how many pumps? It’s not uncommon for a system to have two pumps, separated an LLH or buffer. Maybe even a third of there’s underfloor too.
It’s a Grundfos of some description, just the one internal to the HP. Looking at more recent numbers (April), the HP pulls maybe 112W or so in a flow temp check run. In my defence, prior to Feb when Daikin came and altered the settings, it would turn on 60-70W of tape heaters on the plate exchanger in/outs whenever the circulation pump was on, which makes it a total of ~180W. Nonetheless, it’s more than 100W!
Electric power measurement is using a Tuya-based box with a CT clamp, which appears to be 2-3% underreading compared roughly to the SMETS1 smart meter. I’m looking to improve this, but have other more urgent things to fix in the meantime!
Agreed with moving the threshold up to 200W or having it user configurable.
It’s becoming quite apparent that the larger heat pumps are starting to dominate the top of the charts.
I think it would be useful to have a filter option somewhere so you can select the size you want to look at or compare, ie 5kW? or radio button where you choose multiple sizes if you want?
ie, from the Rating column?

I’m not too sure abut this, the default 90 day view does indeed have quite a few larger heat pumps since larger heat pumps are often installed in bigger poorly insulated properties that require space heating demand in the summer months, and have high DHW demand.
If we look at systems over the last 200 days, it’s a different story:
Agree, that’s a good idea
