How change IEEE(=MAC) in CC2531

[espinardo]

Hello everyone!

My CC2531 broke down a while ago and I ordered a new one to replace in my Zigbee2MQTT system.

I flash my new coordinator as before with the firmware:
https://github.com/Koenkk/Z-Stack-firmware/tree/master/coordinator/Z-Stack_Home_1.2/bin

So far everything is correct, I see my device.

The problem comes when I modify my configuration.yaml, I have to do it because the new device has another ID.

/dev/serial/by-id/usb-Texas_Instruments_TI_CC2531_USB_CDC___0X00124B000151B1F4-if00

Next I can start Z2M and see my devices, but apparently these would only pay attention to the old Mac, because I only have error messages when trying to act on a light or device.

In this thread there are two links that seem to show how to change the MAC of the CC2531, but they are broken:

https://github.com/andreasbrett/zigbee2mqtt.io/blob/patch-1/information/cc2531_backup_stick.md#how-to-clone-your-stick-windows-only-currently

Has anyone been able to change the MAC so as not to have to register all the devices in Zigbee2MQTT again?

Best post Zigbee2MQTT querstions to -> https://github.com/Koenkk/zigbee2mqtt/discussions but FYI, copying IEEE address in in Z2M FAQ:

https://www.zigbee2mqtt.io/guide/faq/#how-do-i-migrate-from-one-adapter-to-another

https://www.zigbee2mqtt.io/guide/adapters/flashing/copy_ieeaddr.html

Another unofficial alternative would be to use zigpy-cli to backup one and restore to the other as that automatically copies the whole network and the IEEE address, read this discussion:

Koenkk/zigbee2mqtt#16478

FYI, zigpy-cli and Zigbee2MQTT gateway backups are not compatible even though both use "Open ZigBee Coordinator Backup Format", that is because the Zigbee network backup is only a high-level and stack-agnostic backup of your device's network data (written in the Open Coordinator Backup Format) but it at least allows you to snapshot the device state and move your network between any hardware and firmware versions supported by zigpy-cli. This backup format is human-readable and fully documented so users have to option to manually fill out or change the appropriate information by hand to form a network if they are migrating from a Zigbee Coordinator that is not currently supported.
