Well interestingly I don’t think it had much effect on the steady-state power consumption, although that probably makes sense given that it was a capacitor(s) that was replaced.
At a high level on a long timescale, you can certainly tell when the capacitor was replaced though:
Looking at ~3:30am on the days before/after replacement, to get an otherwise electrically-quiet period:
-
Before @ 3,850 W steady state, ~400W baseline = 3,450W
-
After @ 3,600 W steady state, ~330W baseline = 3,270W
However I did notice while grabbing these images that there is a definite correlation of steady-state consumption with ambient temperature. So I didn’t control for that between these two images. For example here’s from a little earlier today, with a nice warm 110deg ambient temp:
4740 W, ~420W baseline = 4320W
I don’t have a lot of knowledge on heat pumps though, so maybe that’s well known? I’m happy to donate my data to the Sense team for investigation if needed.
