I typically don’t check Sense labs (because I’m typically on the app vs. desktop and for the longest time the labs on the app version does NOT work - i get error 404 page not found). Anyways I was on my desktop version and saw some spikes in voltage. Normally I wouldn’t be too worried. But if you look at the screen shots
2/16 8:00 both lines went down to about 45v
2/17 7:28 both lines went down to about 88
Dips / Droops like that can’t be good, but only 4 in a month (really only two events), not so worrisome in my mind, since the instantaneous measurement is only for a second.
And then there is also this caveat at the bottom of the Power Quality chart.
*Note: Sense may incorrectly classify other issues as a voltage dip or spike, such as a network connectivity issue or loose CT connection.
