@jn1,
All of this is very helpful in working through the mystery.
- Your rate plan is EL1, the basic residential plan (no funky commercial 3-phase electricity for your building)
- Billing cycle = 8/13 through 9/14 = 32 days
- 2,383kWh used = 74.47kWh / day
- That is indeed a lot of usage for what you describe, but matches up with what Sense is seeing. Just to put it in perspective, I have a 4,000 sq foot house with two AC units and 2 EVs, and as you saw, my usage was only 1,868kWh
- You could easily double check Sense by comparing the monthly Trends > Usage against your the average graph on your bill, but I’m now assuming that Sense is accurately matching your bill
On to diagnosis -
- It’s time to look at your main breaker panel where the Sense was installed to see what is wired into that panel. Hopefully your breakers are labeled and correct. It’s also important to know whether the mains that Sense is connected to go to just your panel or other panels in the building (yes, that happens).
- I’m wondering whether your meter is solely for your unit, or whether it also meters the “house” circuits ? We own a 4 unit building in Monterey, CA and that building originally had all of the laundry room and central hot water metering on the Unit 3 meters. We eventually separated, into a separate set of “house” meters. Figuring that out would require an electrician looking at the building wiring, though who ever connected up your Sense could have likely seen suspicious signs of a “parallel panel” to the one for your unit.
FYI - the link below shows what a “parallel panel” looks like in a single family residential setting - in several cases Sense users have attached the Sense to just one panel of two parallel panels, so Sense was missing lots of energy usage that the utility meter was seeing. In your case, the issue might be that both Sense and the utility are reading two panels, when your apartment usage is only one of those two.
