Frigate Blueprint never triggers, assume problem with MQTT config

My setup is as follows:

HASS as a VM on a NUC with a Coral TPU passthrough the NUC
Frigate as an add-on through HACS
Frigate integration
Mosquitto Broker as an addon
Frigate blueprint used from here: HA_blueprints/Frigate_Camera_Notifications at main · SgtBatten/HA_blueprints · GitHub

The automation based on this blueprint never gets triggered and I can’t understand why.

My frigate.yml

mqtt:
  host: core-mosquitto
  port: 1883
  user: frigate
  password: <snip>

My Mosquitto broker

logins:
  - username: frigate
    password: <snip>
require_certificate: false
certfile: fullchain.pem
keyfile: privkey.pem
customize:
  active: false
  folder: mosquitto

And I see that my automation never gets triggered. Even when there is a detection which I can see. I’ve installed MQTT Explorer addon as well and it shows frigate (see image) but still no trigger. When I try to publish frigate/events or frigate/reviews the automation is also not triggered.

No clue what’s going wrong, can you help?

I’ve tried adding

topic_prefix: frigate
client_id: frigate

to the mqtt config in frigate.yml but no dice.

HACS does not have add-ons.

Also if you are using the mosquitto addon, don’t create users in the addon settings. Create a home assistant user, and that user will have access to mosquitto by default.

Thank you! Apparently just using the default user, so removing the login and adding my home assistant user name and password to the frigate.yml for mqtt works
