@Dark1886 This is a post with many links discussing this effort.

The first announcement I saw of the satellite was on The Verge in April of this year.

The satellite was also discussed in the Year of Voice Chapter 7 Livestream, at about 01:58:00.

It’s important to note that the “ReSpeaker Lite” is a different product than what Nabu Casa is developing, even though they have similar internals.

So we have 3 voice satellites that should be available by the end of the year:

All three will feature some variant of the ESP32-S3 running ESPHome and the XMOS XU316 chip for audio processing. They will differ, however, in their enclosures, sensors, and LEDs, buttons, expansion ports, etc. The hope is that there will be something for everyone :slightly_smiling_face:

Hi, I’m making my voice assistant with a rpi4 and a Raspiaudio Ultra++, I download the drivers following the instruction on the website (GitHub - waveshareteam/WM8960-Audio-HAT: The drivers of [WM8960 Audio HAT] for Raspberry Pi), anyway it’s a wm8960 soundcard and you can find them easily.
In my case I can install wyoming, openwakeword and it’s kind of working and can arecord and aplay, sometimes my rpi recognise the wake word but then get stucked. I have found that the service wm8960-soundcard.service failed to start and it looks it records the wake word once, then it crash.
the service log shows:

I am not sure if I’ve done something wrong, at the moment I think there’s nothing to do with HA yet.
Someone have advice about how to deal with this problem?

Later this eveving I can post the wyoming service config.

I had a read of the repo you provided and the first thing I noticed was that it is recommended to manually build the application. Did you do that?
The other thing I noticed was that there are a few open issues that describe an issue with the application exiting prematurely. I suggest reading through the open and closed issues and see if there are any tips that get you going. The last advice I can give is to open your own issue for the developer to review and possibly comment on. Let us know how you make out.

@pcwii thank you for the reply, I am not a programmer, this is just my hobby. I have double checked all the issues and it seems there are very similar opened, I will try to find a workaround, or carry on with Wyoming satellite and the integration on HA if the sound card service is not “essential”, since I could aplay and arecord.
I will update this.

Could you please help me or share the config?
I am stucked here:

Even if on the satellite there is the degub message “Audio streaming to server has started” in HA I still cant see the “assist in progress”… (but the mute button is working)

I made my own personal Voice Assistant using the Wyoming Protocol with Pi Zero 2W and a ReSpeaker 2Mic HAT for use with Home Assistant.

It’s got on-device wakeword, volume ducking, multi-room audio support using snapcast, tts. I used an old beats pill as the audio output which sounds way better than the cheaper DIY options!

I have made an in-depth step-by-step tutorial if anyone’s interested in making their own.

Hello, I ran into this nice project on YT and basically led me here. I have a PI 5 laying around and also the ReSpeaker 2-mic Pi Hat, and I followed the instructions from the GitHub for the Wyoming Satellite driver and all of the dependencies, but for some reason my PI 5 does not want to capture and run a record test.wav. I also used ChatGTP to assist me in this process and took me on a wild-loop with nothing resolved. My question is, is this project only compatible with PI W? Thanks for any feedback!

I’ve it running on a Pi 3 B however I used a separate mic and speaker using this install process. Try this thread to see if it helps resolve the issues: https://github.com/HinTak/seeed-voicecard/issues/19
