Troubleshooting

Сoordinator does not detect the dongle

Make sure your ZigBee network is open
Make sure the dongle is within range of your ZigBee network
Activate pairing on the dongle manually

The dongle appears offline after a while

This may not be true. Z2M marks ZigBee devices as offline if they do not report anything for a long time, but the router firmware has nothing to report (the device does not have any sensors) so the system may mark it as offline.

If the device is truly offline, all devices that were connected through it will become unavailable.

If the device offline then the most likely reason is that it is outside the coverage area of your Zigbee network.
