From a previous post to add context:
I have four that were working perfectly but three are now having issues. All are using the Zigbee Motion Sensor MC driver.
One is stuck with “motion detected” since this AM. A second is one showing a history of “motion” then “no motion” continuously since this AM. The third hasn’t show any motion even though I was walking around it all day. The fourth is working perfectly.
Update. I removed the top two batteries for two minutes in the one stuck showing motion. It’s now working properly. The one showing constant motion/no motion and the one not detecting motion started working properly without me doing anything.
Do you have enough Zigbee routers (AC powered devices) in your Zigbee network? Have you tried to place them close to the SmartThings hub while pairing? Sometimes it helps to switch the Zigbee channel.
Oh well. Please disregard all post.
