When I started to troubleshoot this, I started wondering why I have used a third-party broker. Maybe it was before I started with docker…
So i just fired up an own MQTT-broker in Docker. I added this to my docker-compose.yaml (see my full docker-compose.yaml file at the end):
mqtt: container_name: mosquitto image: eclipse-mosquitto:latest ports: - "1883:1883" - "9002:9001" volumes: - /home/robert/mosquitto/config:/mqtt/config:ro - /home/robert/mosquitto/log:/mqtt/log - /home/robert/mosquitto/data/:/mqtt/data
I had to map port 9001 to 9002, as Portainer uses 9001. Not sure if I actually need the 9001 port. Looks like it’s for websockets?
To only start the MQTT-container in my composer file, I typed:
docker-compose up mqtt
I had to change the configuration.yaml in HA, with the new MQTT settings. As this is now running locally, i probably wouldn’t need to have the config in my secret file.
mqtt: broker: !secret DOCKER_MQTT_HOST port: !secret DOCKER_MQTT_PORT
I used MQTT-Explorer from Windows store to see that it was working.
