MQTT-integration <-> z2m

Configuration Zigbee
1

So … I broke my zigBee-2-MQTT integration and now I need to setup it up again.

I’ve got my ZigBee-2-MQTT setup on a RaspberryPi in a docker installation.
I can verify that z2m talks to my MQTT-broker in HomeAssistant, but I don’t see any trace of my devices from z2m in HA.

My MQTT integration conf..
Discoveryprefix - homeassistant

Enable Birth mess. CHECK
Birth mess topic - homeassistant/status

Enable Will mess. CHECK
Will mess topic - homeassistant/status


z2m conf. (Hass integration)
Homeassistant discovery topic - homeassistant

Home Assistant status topic - homeassistant/status

z2m conf. (MQTT)
Base Topic - homeassistant

Check HA’s log file

A common problem is that you’ve set the frontend url value in Zigbee2MQTT to something that’s not a valid URL (eg 192.168.0.42:8080 instead of http://192.168.0.42:8080) - and if that’s the case it’ll be quite obvious in Home Assistant’s log.

Do I need to adjust the Bond host as well or is it just the URL?

To be clear my HA and broker is on 10.0.100.8 while z2m is on 10.0.100.20:8080

Did you check HA’s log file yet?

I think we may have found our reason…
Now I just need to find where to adjust the ‘homeassistant//bridge/config’ so we don’t get a ‘…//…’

Why … why does your URL have a space in it?

I noticed the space and that was the cause of the problem. :slight_smile:
