CNX Software wrote up Meta's Muse Gadgets project on 12 October 2026: open-source SDKs that turn off-the-shelf ESP32 boards or a Linux box (Raspberry Pi and similar) into hardware companions for Muse, Meta's personal AI agent. The code lives in the facebookincubator/muse-gadget-sdk repository under Apache 2.0 for most of the tree. Meta first framed the side project earlier in October; CNX's piece is the clearest ESP32-focused summary for makers.
What you can build
The ESP32 Device SDK flashes firmware that connects Muse to your home Wi-Fi, drives a display, handles audio in and out, and talks to buttons, sensors and actuators. Meta points builders at boards such as the Waveshare ESP32-S3-Touch-AMOLED-1.75C and the Seeed reTerminal E1002 e-ink panel, with the ESP32-C5 DevKitC-1 as the quickest default in the ESP32 README. The Linux Device SDK turns a spare Pi into a gadget and explicitly mentions letting Muse handle sysadmin chores or a Home Assistant setup. A third directory of community "skills" covers hardware ranging from printers and TVs to ESPHome devices and other smart-home gear.
Pairing needs an SDK token from gadgets.muse.ai and Developer mode in the Muse iOS or Android app (Settings > Devices); paired boards show up as MuseGadget. Builds use ESP-IDF 6.0.1. Meta also made about 5,000 Muse Home Link units on ESP32-C5 (dual-band Wi-Fi 6, BLE, 802.15.4, 8 MB flash and PSRAM) free for US Muse subscribers while stock lasts, shipping in October.
Why Home Assistant people should care - carefully
The interesting bit for this audience is the Linux SDK's Home Assistant mention and the ESPHome-related skills: Muse can sit next to an existing local stack rather than replacing it. That still means handing an AI agent a path into your network. CNX's comment thread made the obvious joke about giving Meta root. Treat this as a hobbyist experiment on a segmented VLAN, not as a drop-in replacement for local automations you already trust.
