What is your always on usually around?
Always On isn’t a “live” metric. Its a number generated by sense using some calculations of power history over the last 24-48 hours. When I’ve had it where my Always on is higher than actual usage, usually means that wihthin the last 24-48 hours, you had a high power device that ran for long enough, that Sense put it into the Always On category. Then that device got turned off today (or last night) and the system hasn’t had time to detect that it is no longer running, so the AO number stays high, even though the whole house consumption is actually lower. Since its summer, I would guess that maybe you have some ceiling fans or an attic fan or something that maybe ran consistently for a few days, but now have turned off because its cooler or something like that?
Know that even though AO is reading high, Sense is properly tracking your total usage based on actual electric flowing through your mains, so your daily/monthly totals will still be accurate.
