Mystery Device: 700W for 2-3 seconds every 30 seconds

Loving this thread.

How did I not think of the fascinating energy signature of a printer! Possibly because Sense hasn’t ID’d it and I print infrequently.

So, I just quickly migrated my printers onto a TP-link Kasa HS300 so I can look at the curves and am amazed at the peaks. Mine, a Brother HL-5470DW, actually spikes at what could even trip a 15A circuit and the 1875W HS300 but is brief enough to not cause problems.

First peaks are printer power-up and following 3 are single page prints.

I have a second Sense that I use for testing that I’m going to temporarily put on the printer alone and try and grab some more details.
