Meta open-sources Muse Gadgets ESP32 firmware and Linux SDK; Home Link kit for US subscribers

On 2 October 2026, Meta open-sourced firmware and device SDKs for Muse Gadgets — do-it-yourself hardware that connects Meta’s Muse AI agent to displays, buttons, sensors and actuators — and introduced the Muse Home Link, a USB-C device that links Muse to a home network. Unite.AI summarised announcements by Meta executive Nat Friedman, who pointed builders to an API token and the project’s GitHub repository.

What’s in the SDK

According to Unite.AI, the code lives in facebookincubator/muse-gadget-sdk under Apache 2.0 (as-is, no warranty), with esp32, linux and skills directories plus README and AGENTS.md files for coding agents. The ESP32 Device SDK connects off-the-shelf ESP32 boards to Muse (optional screen, audio, sensors). The Linux Device SDK can turn a Raspberry Pi or Linux box into a Muse gadget with custom commands (examples include sysadmin chores or Home Assistant). Gadgets need an SDK token and pair via the Muse app (iOS/Android) under Settings → Devices after Developer mode; they appear with a MuseGadget prefix. Meta frames the release as a for-fun project for hardware hackers and warns of bricked boards and voided warranties.

Muse Home Link

Friedman said Meta manufactured a batch of 5,000 Home Links, free for Muse subscribers in the United States while supplies last (one per subscriber), with units expected to ship in October on a first-come basis; claiming holds a place in line, not a firm order. The device is described as USB-C powered and able to talk to smart-home gear and anything exposing HTTPS, including DIY local HTTP APIs; Home Link code is also open source per the posts. Featured community project ideas listed on Meta’s page include Raspberry Pi / Home Assistant builds and various ESP32 display boards sold by third parties.
