ROUTE_ERROR_ADDRESS_CONFLICT for "0"

I keep getting hundreds of lines with this in the Zigbee2mqtt logs…
info: zh:ember:ezsp: Received network/route error ROUTE_ERROR_ADDRESS_CONFLICT for “0”.
Just replaced my Zigbee2mqtt co-ordinator with Sonoff Dongle-Max
Everything seems to be working OK but a bit worried something may break down the line
Tried deleting things from zigbee network shown above the error, but nothing seems to stop the errors, so I am stuck as to what it is

Was your old coordinator also a Sonoff? If so, read here Sonoff Dongle MAX (dongle-m) stability issues. Poor result - #4 by humingchun

Hi ShadowFist
I have switched from a failing smlight slzb-06m
I say failing because it occasionally would power off and was told to return it for repair, but I needed a replacement saw the sonoff with good reviews
From the link you showed, Seems I have to delete all items from zigbee and start a fresh network.
I did try on a backup machine to install the zigbee afresh and did not see the errors but this was with no devices.

Hi @berni-parrett , thank you very much for using SONOFF Dongle Max.

If you are using Zigbee2MQTT, we would suggest starting from a new/clean Zigbee2MQTT installatiion.

If you are using ZHA, we believe the migration from old Zigbee adapter to new adapter is much more smooth.

Please let me know if you need any help at any time.

Hi @berni-parrett

Please refer to FAQ | Zigbee2MQTT for migrating from one adapter to another.

Basically, you need to copy the IEEE address of your old Zigbee adapter, and paste it into Dongle-M’ Web UI -> Z2M&ZHA -> Change IEEE address -> Flash custom IEEE address.

You can get the IEEE address of your old Zigbee adapter from Zigbee2MQTT’ Web UI -> Settings -> About page.
