Bonsoir,  
Je viens de relire ce sujet: [Tuto installation zigbee2mqtt et broker…](https://forum.hacf.fr/t/tuto-installation-de-zigbee2mqtt-et-broker-mosquitto/23103/45). et les autres tutos sur ce sujet.  
Il est recommandé de supprimer ZHA et Deconz. J’ai supprimé Deconz, ignoré ZHA qui voyait bien ma clé Combee.  
Est ce suffisant?  
Mosquito démarre sans souci:

```auto

mais toujours pas zigbee2mqtt:

```auto

```

config zb2mqtt:

```auto
data_path: /config/zigbee2mqtt
socat:
  enabled: false
  master: pty,raw,echo=0,link=/tmp/ttyZ2M,mode=777
  slave: tcp-listen:8485,keepalive,nodelay,reuseaddr,keepidle=1,keepintvl=1,keepcnt=5
  options: "-d -d"
  log: false
mqtt:
  base_topic: zigbee2mqtt
  serveur: mqtt://localhost:1883
serial:
    port: >-
      /dev/serial/by-id/usb-dresden_elektronik_ingenieurtechnik_GmbH_ConBee_II_DE2234130-if00
    adapter: deconz

```

Je n’arrive pas à voir ce qui cloche dans la config mqtt:

```auto
logins: []
require_certificate: false
certfile: fullchain.pem
keyfile: privkey.pem
customize:
  active: false
  folder: mosquitto

```
