Hey there - we used to have the Data Science team manually review a user’s Power Quality if we suspected a floating neutral (which have pretty distinctive waveforms and can be a serious fire hazard.) Since then, we’ve released a lab project in Sense Labs that does this on a reoccurring basis, just because it was quite unsustainable to run manual checks with a small team (you can find the Labs project here.)
We’re very limited in what we can “see” as the cause with Power Quality issues outside of Floating Neutrals, which is why the best feedback/suggestions users have received in the past are typically from other users in the community with experience dealing with these sorts of things. I’d definitely recommend waiting to see if you get any feedback from users over the next few days before I check with our Data Science team.
