Can you configure Audio Kit v2.2 buttons to send MQTT messages to home assistant ?

[rofo69]

I have been struggling to find any information on this on the web.
Chatgpt sent me down a rabbit hole and suggested that if I add these keys to the NVS editor I could sent MQTT messages to HA:

mqtt_enabled = true
mqtt_broker = <YOUR_HOME_ASSISTANT_IP>
mqtt_port = 1883
mqtt_user = <YOUR_MQTT_USERNAME>
mqtt_password = <YOUR_MQTT_PASSWORD>

And then change a button mapping like so:-

{"gpio": 5, "type": "BUTTON_LOW", "pull": true, "normal": {"pressed": "MQTT:homeassistant/squeezelite/button/playpause"}},

This appears to make the device attempt to connect to my MQTT broker, but I get an error saying I am sending a null username and password.

Also, using serial debugging, its complaining about the button config saying:

[0;33mW (2899) config: Value not found for key MQTT:homeassistant/squeezelite/button/playpause

Is what I am trying even possible ?

Hello rofo69,
I tried the settings as well.
Unfortunately, it does not work for me with the I2S-4MFlash-1681 firmware.
Do you have any suggestions, or does it work for you?
