Sense discovered a new device of type ‘light’ that I found to be the vanity lights in the master bathroom. There are 6 x 60W incandescent lights for a total of 360W. The lights are connected to a Lutron “Diva” DV-600P dimmer. When I turn the lights on, I see about 360W on the Sense Power Meter. So far, so good. Over the next few minutes however, the power consumption rises to about 1,100W. It’s not a gradual increase in consumption, see the attached graph. Notice that it drops back to the expected level, before rising again. I replaced the dimmer with a simple on/off switch and I see the expected binary on/off power consumption, but not in the Power Meter. I’m assuming that Sense recognized the dimmer’s electrical signature not the lightbulbs.
My question is: Is the dimmer at fault or is Sense confused about the actual power consumption?
