I supposed I have more “electrical stuff” than most. Between being a computer person, with 6 to 10 machines on and off all the time, and being a ham radio operator with power supplies that are on and off, I think I have totally confused sense. After a couple of months, it seems to have found one coffee maker (there are two on every day) and one garage door opener. It found a second garage door opener and reports that often. Shame I don’t have one.
It really is quite useless, and if you would just let is tag some stuff while we watch it turn on, a lot could be narrowed down.
I also have two oil burners (one for hot water and one for the TWO air handlers). It has no clue on those.
What I have found useful, is to stand at the fuse panel and turn everything off (except sense) and watch for usage as I turn circuits back on. I was able to find a 100w drain that was always on and did not need to be. Somethings use more or less than you thought! So at least it is fun to play with.
