MQTT doesn't connect

[AlexMohanMD]

Hi,

I receive no MQTT data when entering my MQTT details

Logs from mosquitto:

error: received null username or password for unpwd check
2025-09-08 19:01:27: Client tauri-plugin-mqtt-client disconnected, not authorised.

Also sending config to plate doesn't work. Can't check the design as the code isn't public.

Thanks

Hi,

Thanks for your feedback.
Please try without the username/password. I will look into this issue.
So temporarily disable the username/password on your mosquito and it should work.

Hi - this isn't possible with the default HA addon:

Note: This add-on does not support anonymous logins; all connections must use a username/password to connect. allow_anonymous true nor any anonymous ACLs will not work with this add-on.

Just FYI - no real desire to setup a new MQTT instance for this so unable to test this for you
