Some of my online devices appear offline in the SmartThings hub

Last Update date : Feb 24. 2022
Smartphone with devices in the SmartThings hub.

If some of the devices connected to your hub appear offline, check the following:

  • Check that the devices are turned on. 

If a device has not been connected in a while, the battery may have died. Check the battery and replace it, if necessary. Then recheck the device connection again.

  • Check the distance between the hub and device, and for any obstacles that may be blocking the signal. Another device may have functioned as a repeater (Zigbee Repeater) between the malfunctioning device and hub. Removing such a device may impact the connections of other devices.

Move the offline device as close as possible to the hub, with no obstacles in between and recheck the connection status. 

  • Restart the SmartThing hub by turning it off and on. Then recheck the connection status.

  • If the affected device still appears as offline, delete, and re-register the device.
