[Solved] Multiple Zigbee2MQTT Instances truncate the other's devices

mitchins · October 23, 2024, 8:44am

The Problem:
I added a Zigbee coordinator on my hass instance to run Z2M as an add-on. I have added the presence sensors within Z2M and they seem well connected with quick state updates.

So this one’s really frustrating me because I have my Valetudo operating just fine on MQTT as well as an old instance of Zigbee2MQTT on a pi 1 running in side my shed. (no issues).

As mentioned, I can restart the Z2M add-on and the logs will show a whole bunch of activity like the logs at the end, but after adding it, it decides to remote it! I’ve tried setting the logs to debug level, but it just won’t tell me why it’s thought to delete it.

After a hunch, I killed the secondary (external) Z2M instance, and restarted the add-on. The devices stayed.

I’m a bit confused, people have reported running multiple Z2M instances. Given many different devices use the same Mosquitto broker… it’s a bit perplexing why there should be an issue.

You need to change the topic prefix for at least one of the instances in the Z2M settings.

Thanks, I have done this and it indeed solves it.
