Hi.
In my openhab log i have an error : Starting MQTT broker connection to ‘192.168.10.5’ with clientid d3b1a914-eff9-4661-bd22-f161d2c325.
It seems it is an old MQTT broker, but i cannot find it my things to remove it.
I can see my working MQTT broker:
Similar to this one OH3 MQTT changing broker information ?
I would try to use the API explorer, list all things to check if it is listed there.
You then should be able to delete it via the API explorer or using the karaf console ( which also can be used to list things ).
You also could use an editor and check content of the jsondb file(s). This is most probably not recommended at least you need to be prepared ( backup ) for hickups …
On the “other services” , system MQTT broker, i had some data.
Blanked everything and saved (there is no remove)
Restart the openhab and checked the logs after 30 minutes.
Error is gone.
