Cannot start MQTT Addonb

Hi,

I’m just trying to follow the initial installation instructions for the mQTT addon. I have installed the addon, and started it.The second part of the instructions for configuration are -

1. Navigate in your Home Assistant frontend to Configuration -> Integrations .
2. Use the Add button and search for MQTT
3. Configure the Broker, Port, Username, Password and Submit.

When I go to Configuration** -> **Integrations there is already MQTT: Mosquito Broker under “Configured”, so I cannot use the Add button, it says you can only have one. So, I select the existing one and under the blue header it says “This integration has no devices”, there seems to be no way that I can see to configure it.In the system options button it just pops up another window that doesn’t allow me to do anything.

Next I tried configuring the /configuration.yaml and adding the MQTT configs in there

mqtt:
broker: 192.168.88.66
username: myusername
password: mypassword
discovery: true
discovery_prefix: homeassistant
birth_message:
  topic: 'hass/status'
  payload: 'online'
will_message:
  topic: 'hass/status'
  payload: 'offline'

I did a reboot, and looked at the log file and I have this output -

A couple of questions -

1. do you configure the MQTT addon within the hassio web browser, or via the configuration.yaml?
2. I have 2 config files, one in /root/config and one in /config. I’m using the hassio installer on a pi3, which is the correct config file to use?
3. there is no mosquitto service running, should I see a separate service listed from ps?

Thanks for any suggestions
