And a deeper dive on the one point, on June 14th for the 14:00 hour (1PM to 2PM), that still appears to be a “Conflation” sure looks like something else has gone wrong.
Here’s the “golden” Power Meter view of that hour and surroundings.
And here is that same period showing Sense detections of my upstairs AC. It looks entirely feasible.
But the Ecobee data tells a different story. Sense seems to have missed an off somewhere around 2:42PM !
That’s confirmed by a view of the Ecobee graph:
If I try to transcribe Ecobee Ons (green) and Off(red) to that hour, it looks like this.
Two things I notice:
- I have to mentally shift all the Ecobee times to the right a little. There’s a minute or two of delay between when the Ecobee calls for cooling and the board on the furnace triggers the AC compressor. The same when the Ecobee turns the cooling off. I can see it in the the Ecobee to AC / Power meter edge differences.
- Sense has has kept the part marked by the blue arrow as On time for my upstairs AC unit, but looking at my Ecobee data, my upstairs AC went off at the red liner around 2:42PM, almost exactly as my downstairs AC was turning on. I’m assuming that Sense missed the off because of the other unit turning on.
