One of my bathroom exhaust fans was detected, awesome. However it has an rather odd watt usage that I don’t think is accurate. It starts out using a fairly steady 40 watts which sounds about right. However the power consumption then gets erratic and starts dropping consumption then settles down to a flat line of 13 watts. This does not seem correct at all, the fan has no speed control and does not change sounds as it runs, so it is not slowing up. Once it settles in at 13 watts according to Sense, it stays perfect on 13 watts.
I will try to attach some pictures to show what I am talking about.
