I have has Sense for about 6 weeks and it see a toaster oven, hot hot fryer and a popcorn popper as the same appliance, I can understand this as each use about the same power. It also sees the fridge defrost(?) and crock pot as the same, but here the defrost runs 5-7 min about every 24hr where the crock pot cycles many times during the cooking time.
There is an option to say an appliance is not on, but not one to say it is on. I have two A/Cs same make but different models and does not say which is which, sometimes neither. Sometimes sense has it cut off while it is still running. Also it seams it records the same power used regardless of the outside temperature. High temp should be higher power usage, but it just movers it over to Other.
