Announced October 2, 2026 at gadgets.muse.ai, Muse Gadgets let builders flash off-the-shelf ESP32 boards or turn a Raspberry Pi or other Linux box into a Muse-connected device for displays, buttons, sensors, actuators, and local services such as Home Assistant. The facebookincubator/muse-gadget-sdk repository is Apache 2.0 (as-is, without warranty), with some third-party files under their upstream licenses. Pairing requires an SDK token and the Muse mobile app with Developer mode enabled.
