Hi there, Sense has detected a “Heat 1” device with an interesting signature that I haven’t been able to pin down yet. It turns on for approximately 15 minutes at a time every 12 hours or so, typically between 1:00 - 2:00 local time. Screenshot attached.
The semi-regular pattern (and the timing of the cycle in the middle of the night) suggests to me that it’s not anything human-initiated, but I’m struggling to think of an appliance that might be the culprit.
Likely a fridge/freezer defroster.
That said, correlate with peaks in the main Power Meter vs the detected device waveform.
Definitely looks like fridge defrost as @ixu pointed out.
Look familiar?
Ah - that makes sense. Thanks both of you!
I don’t see a way to manually trigger a defrost cycle on this refrigerator but the manual says a red glow emanating from the back wall vents of the freezer is normal during that process, so I guess I’ll use that as positive confirmation next time I’m around when Sense detects it 
Really appreciate the pointer in the right direction there.
