Replace a ZBDongle-E sonoff dongle with another ZBDongle-E (EZSP)

[Ferywir]

Hello everyone,

I would like to know if there is a procedure to replace a ZBDongle-E (sonoff EZSP) dongle with the same one. (in case of breakage of the dongle).

I read in the FAQ that if we change the coordinator to the same coordinator, there is no need to re-pair, however, the IEEE address of the coordinator must be changed. For a CC2652, CC1352, CC2538 coordinator there is a software available however for the EZSP what should be done?

Thanks for your help

Good morning,

Has anyone ever had to change their EZSP dongle? Whether it's a POP key or Sonoff ZBDongle-E?

THANKS

See existing discussion for migration workaround to backup and restore ezsp adapter with third-party command-line tool -> #16478

Hi @Ferywir
Did you manage to change the IEEE address on your Dongle-E?
If so, I would be interested in knowing exactly how you did it.
The internet is loaded with tutorials on how to change the IEEE on a Dongle-P, but on a Dongle-E? Can't find anything.
Any help would be greatly appreciated.
thx!

NabuCasa’s universal-silabs-flasher can supposedly do it:

• https://github.com/NabuCasa/universal-silabs-flasher

at least acordingly to their readme:

• https://github.com/NabuCasa/universal-silabs-flasher/blob/dev/README.md#writing-ieee-address

Probably best to ask @Nerivec if related to Zigbee2MQTT as he is working a fork for other things.

@Bekie74 You can write it with the above, or with Ember ZLI, see the docs here: https://github.com/Nerivec/ember-zli/wiki/Stack#write-eui64-nvm3-token
Make sure you have a firmware 7.4.x or above for Ember ZLI.
Make sure you use the format whichever tool you use is expecting.
