@AZAron,
I’m seeing something similar, though I have an added complication. I have two AC condenser units, but Sense started seeing a third, AC 3, back in April, after a number of months of getting things fairly right between my two AC condensers between Sept 17 and April 18.
What has happened over time, is that:
- Sense created a new device AC 3, that gradually took over AC Down, in identifications of my downstairs AC condensor
- Sense AC Down started stealing identifications of my upstairs AC condenser formerly know as AC Up
- AC Up began associating with some other lower wattage device (500W instead of 3.5kW) that probably had a somewhat similar signature. It often doesn’t turn off, until Sense hits the time out period or I tell Sense that “Device is Not On”
When the AC Up bubble is up, I get the “bubbles greater than total usage” situation. The bubble suggests that the power is 3.5kW or so, but the data from data export suggests that it is closer to 500W. Will share some data on this soon. Points to the beauty of having Sense share data with smart thermostats like Ecobee or Nest - a little supervised learning is likely to help.
