Meta published open source code on GitHub for building devices that connect to its Muse AI agent. The code runs on ready-made ESP32 hobby boards and on Raspberry Pi computers. Meta says builders can link Muse to displays, buttons and sensors. The Verge reported on 2 October that Meta suggests a color E Ink reminder screen and an HDMI stick for a big display. It also said Meta made 5,000 Muse Home Link devices, per Nat Friedman, and is giving them away.
Meta's page says every gadget needs an SDK token to pair, and tells builders to read the Gadget SDK Terms first. To pair, a builder turns on Developer mode in the Muse app's Settings > Devices, then looks for a device starting with "MuseGadget". The code uses the Apache 2.0 license, with some exceptions. The sources do not say who issues tokens, whether they can be revoked, or what the terms allow. The Verge says Home Link ships sometime this month; no exact date is given.
This part is our reading, not the sources': the code is open, but pairing depends on a token, so the gate may sit outside the open code. Buyers and builders could ask who grants and revokes tokens, and what the terms allow. The Verge describes community-built skills, such as turning on a light, as part of Home Link.
