Ember to zstack

Configuration Zigbee
1

I’m currently using a Sonoff Zigbee coordinator with Ember MQTT

I am now planning on upgrading to the SMlight dual MR1U. But seems it’s best to use the silicon labs chip for thread and the Texas chip for MQTT

This means I will need to change from Ember to Zstack. Anyone successfully migrated without needing to re-pair everything again.
I plan to clone the IEEE address
Anyone have any other suggestions to make this a simpler transition

From the Z2M docs:

"Switching between adapters requires re-pairing, except when :

  • When the serial.adapter in the configuration.yaml is zstack or ember and the serial.adapter stays the same; e.g. zstack → zstack re-pairing is not required.
    …
    When switching from zstack → ember or ember → zstack re-pairing might not be required, however results might vary as this is not officially supported."

Basically, it’s saying you have a 50-50 chance of succeeding without re-pairing.

Note that if you do that, you won’t be able to use your old Sonoff coordinator (not even as a router) in the same mesh, since you can’t have 2 devices with the same IEEE. You’ll have to find a way to change its IEEE address or else donate it to a friend.

Thanks for that, I read that too. But was hoping to have better than 50/50 odds. I have more than 120 devices and really didn’t fancy re-pairing them all over again.
As to using the Sonoff again, good catch. I was planning to give to a friend who is just starting out with HA

I guess I’ll take the risk and hope for the best.
