Zigbee2MQTT doesn't allow changing dongle IP address

[canoben]

What happened?

I changed the IP address of my SLZB-06 dongle (from x.x.x.218 to x.x.x.141). No matter what I try (restarting the plugin, restarting Home Assistant, reinstalling the plugin), Zigbee2MQTT refuses to use the new address.

Here is my configuration:

and here is the log spewing an error about no connection:

I'm at a loss here what to do.

What did you expect to happen?

I expected Zigbee2MQTT to connect with the new address.

How to reproduce it (minimal and precise)

No response

Zigbee2MQTT version

1.39.1-1

Adapter firmware version

Have a similar issue but mine is I can not change from a USB Sonoff to a SLZB-06 on the network. I set the IP address either in the configuration file or via settings in the application and it is ignored and defaults back to USB. I am on version 1.40.2

Was there any solution, please? I can't change the IP. I found the configuration.yaml, I have changed, but it's not working, after restarts it's always changing back to old IP.

Goto Settings->Addons->Zigbee2MQTT->Configuration

Update the serial section and restart.

Obvious when you figure it out but took a while to find.

Thank you. I just find it out before read you post, but thank you very much.

I just setup completely a new network infrastructure with separate VLANs, subnets, DHCPs, and slowly moving everything to the new subnets, and today I have changed the IP of HAOS and it caused a chaos, it took almost a day the fight with Z2M 😀

It1s a big journey to move everything but it's also refreshed my mind regarding the hidden places of configs and IPs.

checking in for future searchers, this works! Just setup a new home network and dongle IP address was changed. updating the config here resolves the issue
