MQTT Discovery not working?

Installation Home Assistant OS
1

Currently running 0.85.1 and zigbee2mqtt. I believe I have everything configure correctly, but my Xiaomi PIR sensor is not showing up in my entity list. Here’s what my relevant config.yaml looks like:

mqtt:
  broker: homeassistant # This will have to be your mqtt broker
  discovery: true

Here’s a log snippet (the last line is what I would expect to create the sensor):

Any ideas - or am I doing something stupid :slight_smile:

TIA for your help!!

It looks like you are missing the discovery prefix.

mqtt:
  discovery: true
  discovery_prefix: homeassistant

Sorry this doesn’t make sense. I must be a nob. mqtt explorer shows <host> => owntracks => <username> => entity

Home Assistant isn’t picking it up at all but doesn’t throw any errors.

why would there be a prefix given that every single device would be <some device> => username => entity???

Also all of this is done in the UI now and there is no option for the prefix and the instructions are out of date not actually referencing how to configure this in the UI since yaml is discurraged.
