How was your issue detected?
Visited Web app. Re-enabled Labs and immediately saw the report. This aligns with frequent dips / blips we see in the house. Lights flickering etc.
Did you noticed any other signs of this issue around your home?
It may be unrelated, but we frequently have GFI outlets pop on their own. Our high amperage devices are 2 x AC units, an induction cooktop, and an electric oven.

No notification was given, but this may be because Labs seems to have turned off after the last lab went public, so I had to re-enable it and then instantly went to the labs page before it had a chance to notify me of a problem
