The Amazon Echo Dot doesn’t need any introduction. It is a speaker many use for home automation. Home Assistant gives you an open source alternative. Thanks to LocalDot, you can upgrade your 3rd generation Echo Dot with Home Assistant support. Unlike your own speakers, this one sends your commands to a voice assistant server on your own network. The status light and physical mute button work as they were.
You can fit this inside your Echo Dot case. It relies on ESP32-S3 and ESP32-P4 to handle WiFi, audio, listening and everything needed to make it work. Thanks to this, you will be able to use open smart home platforms that you run instead of relying on a third party company that may use your data in ways you don’t approve. LocalDot has an open hardware design. You will be able to access firmware, hardware design files and documentation in the near future.
Here are the main specs:
- MCU: ESP32-S3
- Audio handling: ESP32-P4
- TAS5805 amplifier
- 4-mic array support
- 3.3 × 1.5 in
