Moving physical dongle (Sonoff ZBDongle-E) from USB port to a Homeseer Z-Net box

I’m looking to migrate (physically move) my Zigbee dongle (Sonoff ZBDongle-E) from my NUC to a Homeseer Z-Net box (which will also manage my Z-Wave network). I’m doing this mainly because I would like to be able to locate the Zigbee dongle in a better centralized location in my home, rather than in the basement where it is now. But I also like the idea of separating the HA instance from the Zigbee coordinator to pave the path for easier future virtualization.

I looked around, but didn’t find any articles detailing this exactly – I’m NOT moving my Zigbee network to another dongle (migrate radio) – I just want to move the dongle itself to another location. Right now it’s sitting on this “serial port”:
/dev/serial/by-id/usb-ITEAD_SONOFF_Zigbee_3.0_USB_Dongle_Plus_V2_20220815190320-if00
And it would need to move to a TCP serial port – per instructions here:
Z-NET Integration with Home Assistant (homeseer.com)

I would like to avoid rebuilding the entire network – so is there somewhere where I could change the connection string once the dongle is plugged in to the Z-Net? I couldn’t find a way to do that through the ZHA configuration.

Assuming it is basically ser2net or similar under the covers, all you really need to do is change the port. Unfortunately, it is over complicated due to config flow.

ZHA →
Migrate Radio →
Confirm Stopping ZHA →
Reconfigure Current Radio →
Enter Manually →
Choose EZSP as radio type →
enter “tcp://…” as serial path →
Choose “Keep radio network settings” →
Finish

This would be sooooooo much easier if we could just edit one line of yaml.

Awesome! That worked!
Yeah – I was looking to change that one line, but couldn’t figure out how.
