[Config Support]: enable to get Frigate HASS integration working with MQTT

[leonbrag]

Describe the problem you are having

I have tried two different MQTT brokers , but enable to get Friage Integration working. All the Devices are not populated:

However I can see from MQTT broker that Frigate is communicating with MQTT (this is debug log from MQTT broker)

Version

latest

Frigate config file

mqtt:
  enabled: true
  host: hpdebian
  user: '{FRIGATE_MQTT_USER}'
  password: '{FRIGATE_MQTT_PASSWORD}'
  topic_prefix: frigate
  port: 1883

Relevant log output

KeyError: 'mqtt'

The above exception was the direct cause of the following exception:

What happens if you use the ip address instead of hpdebian in the mqtt section of your frigate config?

[hawkeye217]

I believe mosquitto is the most common mqtt broker for HA. Installable via docker or the addon.

[leonbrag]

It was operator error!

I did not realize that I have to add both:

1. Broker itself (that runs as add-on in docker)
2. MQTT Integration that connects HASS to broker

This is why I keep seeing connection from Frigate to broker (using broker debug log), but not from HASS to broker.
