@BlueCalcite, I don’t think that “AC off” and the large Other can be blamed on the KP115. If Sense sees a device turn on then not turn off for a long period time, it assumes it may have missed an off detection eventually does an “undetected off”. The length of time varies based on type of device. I did some analysis against my Ecobee thermostat data a while back and found that Sense was doing the the “undetected off” about mid-day during a full day AC run similar to the situation you are describing. That AC “off” is kicking all the continuing AC usage into Other.
