I own both the Wemo and Kasa smart plugs. Both will “glitch” infrequently, where they erroneously report (or Sense erroneously records) 0W or >10000W.
Kasa HS110 glitching over 10kW for a few seconds:
Kasa HS110 glitching to 0W, sometimes for minutes at a time; sometimes for days at a time:
Wemo glitchgin to 0W for a few seconds to a few minutes:
The main sense CTs don’t show power changes that align temporally in magnitude with what the smart plugs report [as a Sense device] for these glitches…this is another indicator that the reported smart plug power is wrong when these glitches occur.
Have others noticed this behavior?
I’d curious to learn details for how the smart plugs communicate their data to Sense, an what Sense does to validate it gets the correct data. I’m guessing the glitches to 0W are “missing data”, for which I hope Sense firmware updates could be updated to eliminate; but that the >10kW glitches are caused by glitches within the Kasa HS110. By the way, does anyone know how to view the ~1Hz power samples from the smart plugs from their own GUIs?
