Thanks to Smart Home Junkie’s video (invidious link), I had my Atom Echos as voice recognition boxes with all audio output redirected to a media player of my choice (because the audio on the Echo is super quiet).
Whenever ESPHome updated, I updated my Echos to get the recent ESPHome updates, and then reinstalled the custom yaml for audio redirection.
However, with ESPHome’s recent 2024.6.4 update, trying to install the yaml triggers errors that don’t seem to make sense. For example, here’s a section of the yaml:

On lines 3 and 10 I define unique IDs for the device’s microphone and speaker.
But ESPHome won’t compile, telling me:
- on line 46: Too many candidates found for ‘id’ type ‘speaker::Speaker’ Some are ‘echo_speaker’, ‘echo_speaker_kitchen’.
- on line 57: Too many candidates found for ‘id’ type ‘speaker::Speaker’ Some are ‘echo_speaker’, ‘echo_speaker_kitchen’.
- on line 77: Too many candidates found for ‘id’ type ‘microphone::Microphone’ Some are ‘echo_microphone’, ‘echo_microphone_kitchen’.
- on line 90: Too many candidates found for ‘id’ type ‘speaker::Speaker’ Some are ‘echo_speaker’, ‘echo_speaker_kitchen’.
There are no other occurrences of the word “speaker” or “microphone” in the conf yaml (and I’m not including other yaml files).
I’m assuming most of this config is default, and the only things I care about are forcing pin 21 for the speaker (line 11) and redirecting audio to my media player (lines 45-52).
on_tts_end:you have a media player component while you define a speaker instead. They are not interchangeable. It is likely trying to grab default values from somewhere because of that. Media player is better if you want the device to also play music or alerts through home assistant instead of voice assistant or some preset wav files.Media player is also a speaker using an arduino library (not compatible with esp_adf as that uses the esp-idf framework and not arduino). If you want to use the media player, you have to get rid of
vad_thresholdand the esp_adf.Please follow this yaml for an esp-idf config using the speaker instead of the media player: https://github.com/esphome/firmware/blob/main/voice-assistant/m5stack-atom-echo.yaml
Thanks for the help, @JustEnoughDucks@feddit.nl.
I copied the yaml you suggested and made 2 changes:
I changed the
i2s_dout_pinfromGPIO22toGPIO21:speaker: - platform: i2s_audio id: echo_speaker i2s_dout_pin: GPIO21 dac_type: external mode: mono…and added my
on_tts_endwith the media_player:on_tts_end: - homeassistant.service: service: media_player.play_media data: entity_id: media_player.${media_player} media_content_id: !lambda 'return x;' media_content_type: music announce: "false"This did compile and the audio output from the echo is played on the media_player, but the audio is also played on the Echo itself. Previously, changing the
i2s_dout_pinfromGPIO22toGPIO21prevented the Echo from playing the audio (I think by directing audio data to pin 21, which is not used).I’m not sure what you meant here:
Media player is also a speaker using an arduino library (not compatible with esp_adf as that uses the esp-idf framework and not arduino). If you want to use the media player, you have to get rid of vad_threshold and the esp_adf.I tried removing “vad_threshold: 3” and the “esp_adf” component:
external_components: - source: github://pr#5230 components: refresh: 0s - source: github://jesserockz/esphome-components components: [file] refresh: 0s…but with the same result: audio plays on both the media_player and the Echo’s speaker.
Instead of trying to prevent the audio from getting to the Echo’s speaker, is there a way to just turn the Echo’s speaker volume to zero?
Sorry, I misunderstood what you are trying to do here. I thought you were trying to use the Atom Echo itself as a media player. Disregard that arduino library comment, it isn’t relevant. I just watched the video since I couldn’t earlier.
Indeed what you are doing should work. Are you certain that the upload was successful? With GPIO21 set as the speaker output, the speaker data should absolutely not work. The fact that it does means that somewhere along the line, the GPIO22 is set as the speaker output.
