Post the following to check them: `/etc/openhab2/services/mqtt.cfg` file & `/etc/mosquitto/mosquitto.conf` file Have you installed the MQTT Binding in PaperUI? What do you want to do with OH2 and MQTT? Items, Persistence, other use case? The error (connection refused) is from which log? ---

Hi the mqtt.cfg fil ```auto # # Define your MQTT broker connections here for use in the MQTT Binding or MQTT # Persistence bundles. Replace mybroker with an ID you choose. # # URL to the MQTT broker, e.g. tcp://localhost:1883 or ssl://localhost:8883 #.url=tcp://192.168.0.242:1883 # Optional. Client id (max 23 chars) to use when connecting to the broker. # If not provided a default one is generated. #.clientId=openhab # Optional. User id to authenticate with the broker. #.user=openhab # Optional. Password to authenticate with the broker. #.pwd=habopen # Optional. Set the quality of service level for sending messages to this broker. # Possible values are 0 (Deliver at most once),1 (Deliver at least once) or 2 # (Deliver exactly once). Defaults to 0. #.qos=0 # Optional. True or false. Defines if the broker should retain the messages sent to # it. Defaults to false. #.retain=false # Optional. True or false.

To make sure that I read the files correctly, do the following: Edit your post above (pencil icon, bottom right corner of post) and include the contents of the config files in the following way (without the first space before the three tick marks): ```auto ``` content\_goes\_here ```auto ``` I don’t see a name for your broker in your mqtt.cfg I see `.url=` and `.clientId=` but it should be something like: `mybroker.url=` etc ---

Ok, For the mqtt.cfg file: Un-comment the following lines and replace `` with some name that you want to set (e.g. `myMQTT`) ```auto myMQTT.url=tcp://192.168.0.242:1883 myMQTT.clientId=openhab myMQTT.user=openhab myMQTT.pwd=habopen ``` Your mosquitto.conf looks good. Note: since you have disabled anonymous logins (that’s good), make sure that you have created the user `openhab` with password `habopen` on the Mosquitto Broker (using the password file `/etc/mosquitto/pwfile2`). Have you done this step? (with the `mosquitto_passwd` command) ---

You can test the Mosquitto MQTT Broker with the following commands: Open a ssh login in one window and subscribe to all topics under `openhab`: ```auto mosquitto_sub -u openhab -P habopen -t openhab/# ``` Open another ssh login in another window and publish a message (e.g. ON) to a topic (e.g. command) under `openhab`: ```auto mosquitto_pub -u openhab -P habopen -t openhab/command -m ON ``` On the first window with the subscription, you should see the published message (ON) Does this simple test work? (if yes: your MQTT Broker is working fine and you need to check the openHAB2 configuration of the MQTT Binding again) Ps: You will need to have `apt-get install mosquitto-clients` for these pub & sub commands to work. ---

If you get: ```auto Connection Refused: not authorised. Error: The connection was refused. ``` Then you password file needs to be fixed Create a new one: ```auto mosquitto_passwd -c /etc/mosquitto/passfile openhab ``` Enter `habopen` for the password (twice) Change in mosquitto.conf the `password_file /etc/mosquitto/passfile` Change ownership of the new file: `chown mosquitto:mosquitto /etc/mosquitto/passfile` Restart the Broker (`systemctl restart mosquitto`) Try again the [pub & sub test commands](https://community.openhab.org/t/mosquitto-errors/22685/8) Otherwise, check if the Mosquitto Broker is up and running: `systemctl status mosquitto` ---

switch to root first with: ```auto sudo su ``` and then try again 🙂 (or put `sudo` in front of every command since the user `pi` doesn’t have access to several system directories) ---

I am scratching my head … 🙂 It should have worked… Try the following: ```auto apt-get update apt-get upgrade mosquitto ``` also: check the `systemctl status mosquitto` to see what it says… Somehow your mosquitto server is not working…? ---

Check the permissions of the `/var/lib/mosquitto/` directory. It should be owned by the user mosquitto. To fix this: `chown -R mosquitto:mosquitto /var/lib/mosquitto` Check if the file `mosquitto.db` has been created in there. Otherwise…It may be a problem with your mosquitto.conf file… (some syntax error or something similar) back it up and remove it from `/etc/mosquitto/` folder put in the following simple options in a new one and try to `systemctl restart mosquitto` ```auto user mosquitto port 1883 ``` The Broker should become active (running) If this works, start adding back the other options in your new mosquitto.conf, like: ```auto pid_file /var/run/mosquitto.pid persistence true persistence_location /var/lib/mosquitto/ log_dest file /var/log/mosquitto/mosquitto.log allow_anonymous false password_file /etc/mosquitto/passfile ``` ---
