TECHO5 Dot

Linux firmware that turns a 2nd-gen Echo Dot into a local, Alexa-free voice satellite.

Desktopfree

TECHO5 Dot is open-source Linux firmware that replaces Amazon's Fire OS and Alexa on a 2nd-generation Echo Dot, turning the hardware into a local voice satellite for Home Assistant instead. It keeps the device's seven-microphone array and adds Bluetooth speaker mode, signed updates and SSH access. It's aimed at privacy-conscious smart-home hobbyists who want to reuse old Echo Dot hardware without sending audio to Amazon's cloud.
