I noticed flickering lights occasionally but I have had that off and on for years. I will certainly pay more attention to this in the future. It seemed to be getting worse and increased in frequency earlier this week.
I looked in Sense and found a few occasions in January and nothing until Feb 2 where there were 18 and Feb 3 was 104. I had FirstEnergy out and the found no issues but replaced the 60 year old line to the street. That did not help. The issue turned out to be a water leak in the breaker panel from I don’t know how long ago. It corroded the bus bar where the main breaker connected and you could hear arcing. Had the panel replaced yesterday afternoon and the flickering light issue is resolved. Waiting for the Voltage graph to catch up as it is currently only showing to noon yesterday before the panel was replaced.
I would like to request as others have adding an alert for this type of situation as well as more realtime graphs like the wattage graphs.
Glad to have the problem solved and to have the data to identify how frequently it was happening.
Pulled the CSV data and summarized.
