This custom component gives access to the LED-Strip (everloop), microphones and speakers of the Matrixio-Voice within ESPHome.
It allows to use a Matrixio-Voice as a satellite for Home Assistant voice control.
In this first version, only one microphone of the array is used. I might add a beamforming in the near future.
The implementation is based on the example code which MATRIX Labs provides on their project page: https://github.com/matrix-io.
Follow "Step 1: Raspberry Pi Setup" of https://matrix-io.github.io/matrix-documentation/matrix-voice/esp32/
Unfortunately, the packages of MATRIX Lab are now longer maintained. Checkout the repository of Kunal Bansal https://github.com/qnlbnsl/Matrix-IO if you run into installation issues, especially with the new Rapsberry PI OS Bookworm.
