So here is a moment, where I’m able to confirm, that my home AC unit is running at full power/stage 1 and it’s not a detected device, it’s lumped in with the OTHER Grouping.
This had been a very frustrating experience for me, how is this situation doing for others?
Where is sense at handling this better?
What’s in the groups now is:

How long has your Sense been in operation ? Mine took nearly a whole summer before Sense figured out my two old school AC units got it right.
Here’s a more graphical view on how Sense detections eventually hone in on the actual operation of my upstairs and downstairs compressor units as measured by the Ecobee thermostat commands. The number shown is the weekly Pearson correlation between hourly Sense detection energy usage and my upstairs and downstairs Ecobee cooling runtimes. A correlation of 1 means that there is a perfect linear correlation between energy usage and runtime. 0 means no correlation and a negative number means negat…
Do you have an Ecobee thermostat ? There’s a Sense Ecobee integration that can help with detection over time.
Thanks for sharing!
I think I’m going on my 4th month.
Both of my AC units were discovered between the 1&2 months period, so in that regard, guess I’m lucky!
I have a nest thermostat for my home AC, nothing ‘smart’ available for my office AC, which is a ductless unit.

@joesantanapersonal, thanks for the clearer picture - so you actually had detections, but sometimes Sense is missing them or dropping out. One more thing I discovered is that, at least for me, Sense “lost” some detections when my upstairs AC compressor ran for a long period of time. More on this here:
Updated on 7/24 - added 3 more weeks of graphs
I decide to revisit my AC Sense vs. Ecobee correlation results with a little more of the cooling season under my belt. I had gotten a little concerned since Sense seemed to be falling off in it’s ability to correlate with my Ecobee, especially upstairs, where my AC unit was running far more than downstairs. You can see that Sense’s detection of my upstairs compressor (AC2) dipped for a few weeks, below. The number at the bottom indicates the num…
What I guess it’s happening here is the problem sense has with dual/multi-stage AC and pumps/motors like in pool.
Sense has yet to detect my pool pumps.
What appears to be happening with both my AC units is, somewhat like you’re saying is that it will shift back-n-forth, for whatever period of time, then no longer detect either/or as the ‘detected device’ and just show the usage under other.
You’ll notice that throughout the forums folks mention anything with a variable-speed motor is tricky, due to lack of consistency in energy output and behavior (both of which Sense is looking for.)
Same here. I reinstalled sense last year April. It still hasn’t detected my central AC. Very frustrating.

Single stage, dual stage or variable ? Does it use an Ecobee thermostat ? Sense has found both of my single-stage units…
