Meta’s Muse Gadgets project offers an ESP32 Device SDK and a Linux Device SDK for connecting custom hardware to its Muse AI agent. It’s a do-it-yourself toolkit, not a supported developer platform.

What developers can connect

The two SDKs offer different paths: the ESP32 Device SDK is for ESP32 hardware, while the Linux Device SDK is for Linux systems, including Raspberry Pi. Meta describes project ideas using displays, buttons, sensors and actuators.

Those examples don’t mean Meta makes or warrants the hardware. The project page also names third-party boards and devices, which are made and sold by their respective companies. The SDK code is licensed under Apache License 2.0, with exceptions for specified third-party files and separately licensed assets.

Pairing a device—and the token rules

To connect a build, you need a Gadget SDK token. Meta’s instructions call for enabling Developer mode in the Muse app for iOS or Android, then pairing the device listed with the “MuseGadget” prefix.

Meta’s token terms limit a token to 50 linked devices, including no more than 50 devices shared with others. Token use is personal and non-commercial. Selling or publicly listing a token-bearing device, including through a marketplace or app store, is prohibited without prior written permission.

If you share a device, Meta’s terms require you to explain how it handles information before the recipient pairs it. Collection, retention or transmission of prompts and responses is restricted to the functionality you disclose.

Muse Home Link is a separate device

Muse Home Link is Meta’s own USB-C device for connecting Muse to a home network, so it can communicate with smart-home devices such as TVs and speakers, as well as other devices that expose HTTPS. It is distinct from the DIY SDKs and the third-party hardware used in project examples.

Meta lists an ESP32-C5 processor, Wi-Fi 6 at 2.4 and 5 GHz, BLE 5, 8 MB of PSRAM and 8 MB of flash. The device measures 35 × 42 × 10 mm. The listed processor uses RISC-V architecture and runs at 240 MHz.

Meta’s US subscription page lists a free Muse tier with a usage limit, Power for $20 per month and Maximum for $100 per month. Meta says plan benefits and availability vary by region and account.
