Trying matrix satellite killed my matrix voice

O yeah, the credentials… good call

Yes, check here under MQTT Commands

Not very well documented, but each state can have its own color. Different animations are not yet supported, but is a nice feature :slight_smile:

I decided to expand the satellite system and ordered two Atom Echoes from M5. I wonder, are you still working on local wake word detection?

Sort of :smiley:
But time is very limited atm

I understand. Another question you might know the answer to. I am trying to install the matrix kernel on another rpi, but it seems the certificates on their repository have lapsed, and tech support there is (so far) or no help. Do you know if it is possible to copy the necessary files from a working instance and where they would be?

Never mind the question. All the websites referencing the voice pi setup (matrix, hackster) point to an outdated repository which, confusingly, still has the key but an expired one. Here, for anyone reading this thread, is the correct way to install the matrix software and prepare it for flashing your satellite project.

curl https://s3.amazonaws.com/apt.matrix.one/doc/apt-key.gpg | sudo apt-key add -
echo "deb https://apt.matrix.one/raspbian $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/matrixlabs.list
sudo apt-get update
sudo apt-get upgrade
sudo apt install matrixio-kernel-modules
sudo reboot
sudo apt install matrixio-creator-init
sudo reboot
sudo voice_esp32_enable
esptool.py --chip esp32 --port /dev/ttyS0 --baud 115200 --before default_reset --after hard_reset erase_flash
