This is what I get on a scaled-for-time & wattage overlay … sorry it’s pretty crude due to the low resolution input. Looks like Sense is correctly detecting the ON but failing to detect the OFF cycle due to continued higher power use at that point. That still doesn’t explain the notification mismatch though. It seems the Device waveform is displaying one ON-OFF cycle detection and meanwhile the notification is based on a different detection cycle where Sense is still registering the device as ON.
