Automatic discovery of MQTT credentials

[1technophile]

Hello,

I see that this addon:
https://github.com/mdegat01/addon-amr2mqtt/tree/main/amr2mqtt

Doesn't need to enter broker host and MQTT credentials. Do you think we could leverage the same principle per default?
And only use the host and credentials if they are set by the user.

Good find. I doubt I'll have time to start working on it before mid-December though.

I suspect that we are only missing this:
https://github.com/mdegat01/addon-amr2mqtt/blob/8fdd816e98d74afd53aa2b958e38d86063c0af94/amr2mqtt/config.yaml#L18

here is the doc:
https://developers.home-assistant.io/docs/add-ons/configuration/

Thoughts?
I can do the modification and test.

I would say that - mqtt:want is not related, based on the documentation.
But try it if you want. I'm not an authority on the matter. 😁

I confirm that - mqtt:want is not related.

Just found that the RTL_433 addon doesn't need MQTT credentials also https://github.com/pbkhrv/rtl_433-hass-addons/blob/main/rtl_433/config.json
