@attk11, some quick answers from a long time user. The big picture is that fundamentals of Sense native detection have not changed, though based on my experience, Sense has gotten better at detecting a subset of EVs (EV detection is different than native detection and tuned on a per make/model perspective) and some kinds of HVAC systems (the Ecobee Historic integration might have helped Sense with my HVAC).
From what I remember back in 2019, heat pumps or ECM motors can cause noise that makes it difficult for sense to identify other loads.
Power usage noise from large loads is still an issue, and continues to be one of the reasons that Sense detections can vary widely between households.
I would love to tag every device/circuit. Hanging a CT clamp off my stove and furnace and telling sense that everything on these circuits is my stove/oven/furnace would be nice.
There’s still no user training option, but if you look closely at Sense native detection today, you’ll see that it views waveform detection very differently than you do. Understanding how Sense does it, can help “debug” why a particular device might not be detected.
As it is right now the small burners, large burners, bake, and broil are all different signatures to sense.
Still an issue - different on/off signatures for each because power is indeed different.
With these smart plugs do you need to leave them connected to the same device for sense to know what it is? Ryan mentioned in the above link “It will take time, but the goal here is that you’ll eventually be able to put a smart plug on a device for a couple days, get it detected, and then move the smart plug to another device and repeat the process”. is this now possible?
Sense doesn’t directly learn from smart plugs, so Ryan’s speculation still hasn’t come true. Best approach today is to use 1-2 roamer smart plugs like the Kasa EP25 to look at 48 hours histories of all the plug-in devices in your house. Some devices, that Sense has not found with native detection, that have a wide range of dynamic power usage, are good candidates for long-term smart plug usage. Devices and outlet strips that primarily use Always On are great candidates for NOT using smart plugs - just manually enter their Always On usage into the Always On itemization.
The following is a good thread on best ways to use smart plugs.
