Hi @jrbinqk ,
Unsure if it is, but it sounds a little like you're describing the Tap View connection notification; where the TV's Tap View sensor is detecting vibration and sending out a connection request to a nearby Tap View enabled device. Happens even when connected devices have been removed.
Do you have the SmartThings app on your mobile (or mobiles)? If so, go to SmartThings app > Settings > 'Tap view, tap sound on'; and toggle it to off.
