Heat device mystery


Me Sense has detected a heat device that runs for about 20 minutes per day, using about 150 watts. Since it is on about once per day, I suspect the defrost on the fridge, but that doesn’t make much sign that it’s running (no noise). Any thoughts on how to investigate this?

Here it is. Not much complexity to it,eh?

There’s probably a lot of complexity in that teeny spike at the top of the leading edge… But at 1/2 second resolution (at best), most of that is lost.

1/2 second resolution?

Zoomed in at Max. Still sampled only at 1/2 s cuz that’s what the power meter does.


Finally got a chance to unplug the fridge while this device was on. Sure enough, it’s the fridge.
