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

If your Samsung SmartThings Motion Sensor or SmartSense 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 (original model only) 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 support for more tips on troubleshooting your old SmartPower Outlet.
  • Remove and reconnect your reconnect the Samsung SmartThings Motion Sensor or SmartSense Motion Sensor to your Hub. Resetting and reconnecting the device may resolve status problems.
  • The batteries could be dead. Replace them with a new batteries. (1 CR-2477 battery for the Samsung SmartThings Motion Sensor; 2 AAAA batteries for the SmartSense Motion Sensor.)
  • 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.

 

Note: Keep in mind that the Motion Sensor will take roughly 30-40 seconds to change from a "Motion Detected" event to "Motion Detection Stopped." The sensor will continue to display motion until there have been 30-40 uninterrupted seconds of no motion being detected.
