However, I can tell you: it’s not a large motor (would have a sharp spike at the front).
And it’s not on a perfect schedule, so that indicates something that is at least partially dependent on the environment or other conditional factor.
Apologies for missing the time scale from before: I was on mobile, and couldn’t see the bottom of the images in context.
It seems to have consistent peaks, and it appears to just slightly “ramp up” (and then “ramp down” when ending).
This doesn’t look like a battery charging (would decrease over time, or have much sharper peaks).
Certainly not a large motor (would have a spike at the front, unless very efficient, and wouldn’t bother being so efficient for <70w).
Possibly a “smart” light of some kind: fades in and out (though, that’s an unusually rapid cycle)?
Next steps (in my opinion), go to your circuit breakers during a quiet time, and begin switching off circuits… do this slowly: only 1-3 circuits per minute. And try to eliminate the more “noisy” devices first: laptops, etc. that would randomly wake up and use some spike of power and then sleep again.
Remember: sometimes you will get weird behavior: a device may lose connectivity with a device you just powered off, and it will start trying to contact it at high power… so you can see bizarre spikes in power usage right after flipping off a circuit… or, more likely those are just random activity from other devices)… also: obviously, you can’t switch off the circuits for Sense, or your various internet/WiFi devices.
Have you considered using some of the Kasa TP “smart plugs” on certain “noisy devices”? If you have a newer refrigerator, in particular, I’d recommend tracking the fridge. (Obviously, any complex [always on] electronics like a DVR, game station, computer, etc. are also prime candidates: main thing is: “erratic” or “noisy” power usage. Sense loves simple, consistent shapes [well, that aren’t 220v rectangles]. For anything erratic, consider a smart plug, or expect that it will not be well-understood by Sense.)
For example, here’s my fridge (it’s an “efficient” Samsung)…
In the blue section, note how the valleys are smooth. But in the red section, it seems to alternate different power usages every 30 seconds.
In the green section, thats the defrost (the tall rectangle is the heating), the more intense cooling cycle starts right afterwards, and he whole signature varies significantly from day-to-day.
Interestingly, the “every 30 seconds power usage”… that seems to toggle on/off with each defrost… so, the “bumps” will occur after a defrost, and then turn off at next defrost, and so on.
And then there’s the yellow section: which just shows that I put something warm in the fridge, etc. and it had to ramp up cooling for that…
Conceptually, yes: Sense may someday be able to figure out such a complex model, but this is such an erratic device: its much simpler to just put it on a smart plug, and thereby eliminate that “noise” from confusing others potential detections.
