This is my first post - so be gentle!
I’ve had my Sense for about a month, and yesterday it identified a new device and called it Heat 3. Sense detected it once on 10/6 where it ran for 1 minute, then nothing until 11/21 - 11/22 where it ran 30 or so times (for very short periods), and hasn’t been recorded since then. It’s a pretty high draw item, drawing 3000 watts during the starting surge and 2200 watts after that. Based on that I’m thinking this has to be on a 220V circuit? My largest 120 breakers are 20A. Sense has already identified my well pump which draws less than this and has a totally different signature. Here is the Sense list of guesses:
Here is a zoomed in display (4am - 4:30am) of the Heat 3 power meter the morning of 10/22. Even if I zoom all the way in they still show as single vertical lines with no duration:
Then I went to the Now (total power) display, backed up to the same timeframe and looked there. Here is a similar timeframe view (4am - 4:30am) total power:
And here is that same display zoomed in all the way:
Hopefully that gives enough data for someone smarter than me to diagnose what this might be.
