ESP32-LyraT-Mini V1.2 as a voice assistant

ESPHome
1

Hello,

Does anyone have experience using the ESP32-LyraT-Mini from Espressif? I have recently purchased a couple, as the larger stereo version is out of stock.

This is my first ESPHome project, so I am a little overwhelmed. I have so far successfully connected the board and also gotten the onboard LEDs to work. But I cannot get the microphone to work. The board has an ES8311 codec for output and an ES7243 ADC for input.

Did you ever make any progress on this? I’m trying for the first time as well to use esphome. and was able to install the code you provided, but I don’t even know how to tell if it did work successfully…
