Hey @kelchm. We took a deeper look at this for you, and it looks like there’s a few things potentially going on. Grabbed a few screenshots for you, courtesy of Data Science.
Overall, we noticed some typical symptoms of a Power Supply issue - a potential neutral issue and some external interference. It’s also worth noting that right now, the Floating Neutral detector is a semi-manual process. The issues you’re seeing here that are indicative of a neutral issue would be flagged by the next update to the Floating Neutral detector, which you would be able to see in Sense Labs.
In the highlighted region in this image, you’ll see a 1000W load appears to be causing an inverse 3V dip, which could cause flickering of lights (and other symptoms you might have noticed). This is indicative of a neutral issue.
Above, you’ll notice a fluctuating voltage supply. Typically, this could be due to several reasons including:
An in-house appliance which is not monitored by Sense is causing the issue (which you ruled out with the answer to my original question).
Since there is no in-house load corresponding to the voltage fluctuations here, it leads us to believe there is an external issue (neighbor, lines feeding into the house) that could be causing irregularities here.
If you do have someone out to inspect this, or manage to resolve the issue it would be great if you could share that with us here or via Private Message
