Unfortunately I don’t have the time right not to really dig into that thread but it does look somewhat similar.
At the bottom of this post I will attach the response I received back in April 2021 regarding something similar (but different) happening with my oven which is what leads me to believe this is a discrepancy between the two models.
The one thing that gets me is that I’ve noticed on occasion (not often) the bubbles don’t line up with the on/off state in the app. “Devices” will show the device’s currant wattage but no bubble will appear. Or the bubble will remain but the device will be grey. This is different from a bubble not matching up with the “today” or “device timeline” timelines. I probably shouldn’t focus on this as it happens infrequently and is likely a separate unrelated issue, but feel it should be noticed just in case.
Going back to the main issue of the bubbles not appearing or remaining, it does appear as if many of us are experiencing similar issues that could very well be related. Some in support seems to be having a difficult time understanding the issue as well, so it is imperative we all report this issue when we see it in order to get Sense to dedicate resources to get to the bottom of it along with enough data needed to do so.
To clarify, since I preformed the reset a couple months ago, device detection was excellent, much better then previously. Since the reset I had no issues with the bubbles UNTILL I made changes within the past week or so, which leads me to believe this issue is directly related to one of those changes. Hopefully with this information Sense can take an in-depth look to see if one of these changes confused the online model, and provides some insight as to what may be causing some of these issues we are having.
The changes made to my home & account within the past week:
Added KP115 (garage charger 1) to a trickle charger in my garage.
Added KP115 (garage charger 2) to a 2nd trickle charger in my garage.
Added KP115 (Mom’s tv) to a tv in my mothers (Alzheimer’s) bedroom.
Added KP115 (Network /HA) to a UPS that has 2 routers, cell signal booster and Home Assistant desktop.
Added KP115 (AC) to a portable AC. AC has been running since July w/o being natively detected.
In Settings - My Home - Home Details - Cooling, I unselected “No Cooling” and selected “Other” (portable AC).
Replaced Microwave with new model. Sense (accurately) detects it the same as old one (didn’t detect it as new device).
Added Location/Make/Model data to numerous devices.
Sense natively detected Heat 4 (8/13), renamed to Toaster Oven.
Sense natively detected Heat 6 (8/15), renamed to Toaster.
Sense natively detected Heat 5 (8/19), renamed Furnace Fan (turned fan on briefly to circulate air).
@JustinAtSense feel free to share this information, thread and Sense data with the other teams.
Response from April 2021:
To provide some additional context here, there are a couple of different components to the device models that Sense creates to track the usage of your devices. One part is what we refer as the ‘offline model’, which looks at processed data when it reaches our servers and attributes historical data to that device. Another component, which we call the ‘online model’, detects your devices turning on and off in real time and governs the on/off state in the app, as well as the device bubbles. The online and offline models are independent from each other and, in this case, did not line up with each other and led to the discrepancies that you pointed out. Looking at the data from our end, I can see that both parts of the model (online and offline) correctly saw the oven turn off at about 8:40pm, which is visible in the device timeline. However, the online part of the oven model alone picked up the last cycling of the oven’s heating element, as you referenced. However, the correspond ‘off’ event was not seen, resulting in the oven bubble remaining on in the app when the oven was not running."
