Troubleshooting: SmartThings Motion Sensor is stuck showing "Motion Detected" or "No Motion"

If your SmartThings Motion Sensor is stuck showing "Motion Detected" or "No Motion," there are a few things you can try to get it to cooperate. 

  • The Motion Sensor may be out of range. Move it closer to the Hub, or extend the range of your ZigBee network using repeaters. The SmartSense Motion Sensor itself works as a ZigBee range extender if plugged in via micro USB. Go here for more information about creating an ideal mesh network using repeaters.
  • In some rare cases, the old SmartPower Outlet (Smartenit) can interfere with the Motion Sensor's ability to communicate with the Hub. To test this, unplug the outlet for a day and see if the Motion Sensor checks in. If this works, contact for more tips on troubleshooting your old SmartPower Outlet.
  • Remove and reconnect the SmartThings Motion Sensor to your Hub. Resetting and reconnecting the device may resolve status problems.
  • The batteries could be dead. Replace them with a new set of AA batteries. 
  • The battery contacts may be out of position or not seated properly. Push them in firmly to reestablish the necessary contact. Also make sure the batteries are oriented correctly.

If you've tried these steps and the Motion Sensor's status remains incorrect, contact our support team at


Note: Keep in mind that the SmartThings Motion Sensor will take roughly 40 seconds to change from a "Motion Detected" event to "Motion Detection Stopped." The sensor will continue to display motion until there have been 40 uninterrupted seconds of no motion being detected.
