0 w and negative measurements

My Sense has been working fine for months now. Then it started to do this…

It seems to only detected my tp link plug? What can I do?

I would contact support.

Seems like an issue for Support. I would contact them.

A guess: something wrong with your CT clamps/inputs … assuming nothing on that front has been moved around. Posting a longer period Mains waveform would be more helpful but it’s still going to be a Support issue, probably.

Contact support. Times where Sense zeros out could also be due to network issues, in addition to CT sensing weirdness.

Definitely concur here about contacting Support, if you haven’t already.
