Here’s a thought - not all devices that Sense detects become “instant detections” where the device shows up immediately in the bubble. I notice this for my EV charging. I’m not sure how long the posting delays can be, but I have seen situations where my EV charging showed up several hours later in the Timeline and hourly Trends. One shortcoming of the Sense integration is that it only reports the data at the polling point in time and doesn’t backfill. So if Sense post-updates after all the usage has already happened, then Home Assistant will never see it.
I think we’re going to see more of this kind of update with progressive detections.
ps: there are other time issues in aligning Home Assistant data vs. Sense, mostly spurred by the fact that Home Assistant is regularly polling instead of being event/transaction driven.
