Motion notifications when disabled

I deployed two EufyHome 2k Pan and Tilt, and recently enabled HomeKit (which requires disabled motion sensing). I don’t want motion detection.

Every few days, I start getting “motion detected” notifications for just one of the cameras (yes, when there is actual motion) - and not the other. When I check the Eufy app settings, motion detection is still disabled. I have to cycle the setting on/off, and it buys me a day or two, then I start getting notifications again.

Is this a bug? HomeKit related? Anyone else experiencing this??
