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:

esp_adf:

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).

    FYI, here’s the config yaml I’m copy-pasting for all my Echos. The only thing that changes are in the “substitutions” section:
