I have had a ZBT-2 up and running for about 10 days, and today I tried to add my old re-flashed Sonoff Type E dongle as a router.
Flashed as:
Current Device:
ZBDongle-E
Current FW:
Zigbee Router 8.0.2
When the Sonoff is plugged into a usb port the only device found is the ZBT-2:
Not 100% sure what happens under the hood, but if the migration process clones the previous coordinator’s IEEE address, then you can’t ever use it as a router.
Basically (assuming what I suspect is true), you currently have 2 devices with the same address which will lead to a bad time if they are part of the same network.
The only options you have in this case are:
Check if it’s possible to overwrite the address on your old dongle.
