Bonjour, 
I installed Home Assistant for the first time yesterday. I’m not used to it sorry 
Installed with Docker.
privileged: true
network_mode: host
I have already a home automation system working on my network. Jeedom, and zigbee2mqtt (2.6.3) / mosquitto (2.0.22), since few years.
In HA, MQTT integration, I configured that I think right. I receive respond message successfully.
But, no entry . Nothing. After one night, not yet discovery.
In integrations settings, when I tried to listen topic, It works.
And I can write in topic and see homeassistant topic to be sure with mqtt ACL.
I tried to add new device from zigbee2mqtt, It works in zigbee2mqtt, but not appears in HA.
I tried in zigbee2mqtt > settings > interface, I remove url and restart, does not work better.
My zigbee2mqtt config:
homeassistant:
enabled: true
status_topic: homeassistant/status
discovery_topic: homeassistant
experimental_event_entities: false
legacy_action_sensor: false
availability:
enabled: true

In zigbee2mqtt > settings > Home Assistant integration, i tried to change discovery topic, but I got:
[11/11/2025 10:17:51] frontend:api:bridge: Sending {"topic":"bridge/request/options","payload":{"options":{"homeassistant":{"discovery_topic":"homeassistant"}},"transaction":"0srn7-1"}}
[11/11/2025 10:17:51] z2m: Request 'zigbee2mqtt/bridge/request/options' failed with error: 'Extension with name HomeAssistant already present'
This morning, I installed HA on Rpi4 with official image. I installed integration, re-configured and unfortunately I don’t see any device appear in HA.
If you have an idea.
Thanks!
