Home Assistant Core with external zigbee2mqtt server

Configuration Zigbee
,

My working setup was:
RPi running HA core
RPi running zigbee2mqtt

All working fine, until a power cut and the RPi HA died, and no I didn’t have a recent backup :frowning:

The RPi has been replaced with a spare Intel based NUC I had in the drawer. This is running latest HA on latest Ubuntu. But here is the issue : I can not remember how to get the zigbee2mqtt working to the new HA?

The zigbee2mqtt needs to connect to an MQTT server/broker but where should I be installing that? On the RPi with zigbee2mqtt or on the NUC with HA?

I don’t have the Add-On store so I can not just add the broker, but I could manually install a Mosquitto server on the HA machine. Is that the best way?

Advice/suggestions?

If you are not using the addon you can install the Mosquitto MQTT broker on either pi.

Then install the MQTT integration on the Home Assistant pi.

Thanks for that.

I have installed the broker on the NUC that is running HA.
All working!
RPi with zigbee2mqtt is talking to NUC with HA and MQTT integration

Only issue now is that the Hue bulbs don’t have any sort of on/off function - wrong device?

Can’t help with that sorry, I don’t use Hue. Someone else might offer some advice.

Which Hue Bulb?

There may be some help here:

All fixed! I restarted the zigbee2mqtt and it all got sorted!
Needed to see the “light bulb” entity messages and it ok now.
Thanks for the quick answers
