Matrix is good, secure, very versatile, Foss, and easy to use, but I think not easy to set up or manage.

Thanks for the suggestion, @Windex007@lemmy.world, but by the time I saw it, JustEnoughDucks had suggested a fix.

Thanks for the help, @JustEnoughDucks@feddit.nl.

I copied the yaml you suggested and made 2 changes:

I changed the i2s_dout_pin from GPIO22 to GPIO21:

speaker:
  - platform: i2s_audio
    id: echo_speaker
    i2s_dout_pin: GPIO21
    dac_type: external
    mode: mono

…and added my on_tts_end with 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_pin from GPIO22 to GPIO21 prevented 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?

I host Wyoming on a server with an Nvidia 4060ti, and point home assistant, on a vm on another server, to it. It works great.

(sorry about my delayed response, @JustEnoughDucks@feddit.nl )

I’m sure that the install is successful because there are no errors during/after install, the Echo recognizes speech and interacts with Home Assistant, and when I change something in the yaml (e.g., which media player to pipe the audio to) the change takes effect.

Here’s something weird: I believe the default pin for “speaker” should be GPIO22, and when I switch it to GPIO21 it should not work. This works on some of my Echos, but not all of them!

Also weird: I think the standard pinout is:

• GPIO0: Button (Boot)
• GPIO19: LED (RGB)
• GPIO21: I2C SDA
• GPIO22: I2C SCL
• GPIO23: Speaker (PWM output)
• GPIO25: Microphone (Analog input)

Though I don’t know what these mean, I tried setting “speaker” to GPIO18 - which apparently isn’t used- and still the audio comes out of the Echo speaker! But again, only on some of my Echos.

I’d think that maybe some of these Echos are ignoring the GPIO setting for “speaker” and using a default, but these Echos used to work! (that is, they used to not play audio out of the Echo speaker when “speaker” was GPIO21). And so I want to think that maybe the ESPHome upgrade made them stop working, but all my Echos have the same upgrade and yet still some of them work.

Is there a way to config the Echo speaker to have zero volume? If so, I could just set that and then who cares if the audio is piped to it.

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

I use Solokeys. Didn’t know they were defunct. I just bought another from then a month or so ago. I use it for MFA, ssh, and sudo, and I’m trying to config Kubuntu login screen to require solokey but no luck yet.

I like solokeys, but the one I recently bought has NFC and, technically, my pixel7 running GraphenreOS can detect the device, but it doesn’t work. Many people reported this issue. In my experience, NFC is non-functional.

That sounds crazy, but easy to test. Thanks for the suggestion.

Thirded. I self-host it (actually the Vaultwarden fork) and use it on desktop browsers, as a desktop app, and as and Android app (F-Droid). I also store secure notes in it (e.g. end of life instructions for my partner). Very powerful and versatile, and AFAICT, secure.

I’m trying to deGoogle/deFAANG/deBigData so I try to host FOSS alternatives to every service I use on the internet, though some services won’t be possible or practical (e.g., email).

I host:

• audiobookshelf (to stream and sync podcasts between my devices)
• baikal (to host contacts and calendars)
• cryptpad (for collaborative spreadsheets and kanban, though it does more than this)
• drawio (flowchart-like diagrams
• forgejo (my git repos and oauth2)
• homepage (personal dashboard of services and links)
• invidious (youtube frontend)
• lemmy (duh :) )
• minio (S3 object storage)
• mosquitto (mqtt server)
• nextcloud (can do a lot, but I’m only using it to look at Memories for photo storage and management - I currently selfhost Photostructure, but it’s not FOSS)
• peertube (youtube alternative)
• prometheus (metrics monitoring)
• qbittorrent (torrents)
• syncthing (currently only used to sync photos from my pixel to my server, but might be replaced if I switch to a photo management app that has an android app that can sync images)
• tiddlywiki-nodejs (pretty powerful wiki, but I use it just to sync text-based info between devices)
• traefik (reverse proxy in front of everything I host)
• tt-rss (RSS feeds)
• vaultwarden (password management - this is a fork of bitwarden)
• wordpress (for my personal websites)
• xbrowsersync (bookmark syncing between browsers/devices)

I use the d.rymcg.tech framework. It’s a little over my head, but the framework makes it pretty easy to use all the apps. It’s a bit tricky to add new apps to the framework, but it’s fun and all the source is there to learn from and the developer is really nice and really helpful.
