I like many others gave up and went to plan B, which is detailed in the thread here:
I have a chest freezer and really wanted to keep tabs on it’s usage. With the help of a smart plug and the thread above, I can now see it. The really surprising outcome of that exercise is that the signature of that freezer “should be” about as easily detectable by sense as possible - here’s a view of the power meter for just the freezer.
3+ years using sense, and it never found this. Glad I moved on to plan B!
