Using MQTT/Nmap but no known_devices.yaml

Configuration
1

Hi all,

Just starting out with Home Assistant and attempting to get the device tracking working to do some automations based on devices being home or not.

Anyway, attempting to use MQTT and I’ve followed the component guides on here and a couple of forum posts but I cannot seem to get it working.

I have the inbuilt MQTT broker running, and the config confirms this. I’ve then used Zanzito to connect to my MQTT broker and from what I’ve read, Home Assistant should then create a file of known devices, but this doesn’t seem to be happening.
I also have Nmap on in the configuration, and again, no new device file.

Can anyone point out where I’m going wrong and either provide a solution, or point to the relevant docs?

Thanks!

ok, so

configuration.yaml

# MQTT
mqtt:
  broker: !secret mqtt_broker
  username: !secret mqtt_username
  password: !secret mqtt_password

mqtt_statestream:
  base_topic: homeassistant

includes/device_trackers.yaml

device_tracker:
  - platform: mqtt
    devices:
      sean_s8: location/sean
      kelly_s8: location/kelly

Once installed point it to the ha server

All installed
Can see the client connect in the Mosquitto log in Home Assistant:
1518502889: Client MQTT_FX_Client disconnected.
1518502913: New connection from 192.168.255.x on port 1883.
1518502913: New client connected from 192.168.255.x as somerandomhasnowhidden (c1, k60, u’wosak-mqtt’).

I also tested with the the Zanzito application, and again is connecting, so not sure why the list of devices is not showing.
