Two thoughts here…
- The AC could also be stepping on the on-signature of the fan. Here’s an interesting overlay where the AC compressor detection is missing the underlying fan.
Sense stops reporting Window AC mid-cycle - #5 by ixu - Don’t mess with combining until you have a few months of consistent detection. There’s not a huge value in combining the devices, except you see a unified report. And there could be additions and changes in the detections (my AC turned out to be 4 different AC detections that changed over the course of the cooling season)
