Software

firmware

ESP32 Zigbee Coordinator (ZBOSS)

Firmware that turns a stock ESP32-C6 into a full Zigbee coordinator — the ZBOSS NCP protocol for Zigbee2MQTT, over USB or UART.

firmware

SixBack

Brings the six preset buttons on Bose SoundTouch speakers back to life after the manufacturer shut down its cloud — one ESP32 stick on your LAN, no account and no server.

firmware

IP4KNX

Turns a TUL into a full KNXnet/IP gateway — routing and up to ten simultaneous tunnels, with a web dashboard and no knxd anywhere in the picture.

firmware

BREMA for KNX

Firmware that turns the TUL into an MCP server on your LAN, so an agent can commission KNX devices — addresses, tables, parameters — without ETS, knxd or a vendor cloud.

firmware

Thread Border Router (THBR)

A complete Thread border router on an ESP32-C6 stick, reached through the chip's own USB port — no radio co-processor in the host. Runs as a Home Assistant add-on or as a plain Docker container.
