Anybody see anything repetitious like this?

This keeps showing up most of the time - about 80-100 watt cycling. I’m thinking a switching power supply or the like. Any thoughts or ideas to help identify?

my induction cooktop looks like that and sometimes my front loading washing machine

My Keurig coffee maker causes a 400w pulse for 10sec every 2min.

I have been getting something like this from my central air system but only occasionally. Cant figure out if its a problem yet. Have you had any luck?

I’m betting on the switching power supply…
