Tuya Smart filed an 8-K press release on November 12, 2026, announcing the release of Tuya Cloud Devices, an official open-source Skill that enables Meta's personal AI agent Muse to query and control smart devices through Tuya's cloud using a single API key.

Key Highlights

  • New open-source Skill: Tuya Cloud Devices (Skill name: gadget-tuya-cloud-devices) lets Meta's Muse agent control smart devices via Tuya's cloud, with no local device keys, same-network connection, or firmware changes required.
  • Single API key access: Users can apply for a free API key at tuya.ai; the key begins with "sk-" and the two characters following automatically identify the data center, selecting from seven data centers with no manual configuration.
  • Developer platform scale: As of June 30, 2026, the Tuya AI Developer Platform had more than 2,092,000 registered AI developers from more than 200 countries and regions, according to the filing.
  • Platform coverage: The Tuya platform covers 3,000+ smart hardware categories and serves 200+ countries and regions, according to the filing.
  • Safety boundaries built in: The Skill does not expose door lock control, live video, firmware upgrades, network configuration, or device removal; event-triggered notifications are sent at least 30 minutes apart to prevent alert fatigue.
  • Geographic availability: Muse is currently available to users in the United States and Canada, according to the filing.
  • Portability noted: The Skill was originally built for OpenClaw, an open-source agent, and was adapted to the Muse specification; the company disclosed it can be reused across agents that adopt Markdown skills in the SKILL.md format.

Tuya Cloud Devices Skill: How It Works and What It Covers

According to the filing, Tuya Cloud Devices is adapted from tuya-smart-control, Tuya's official open-source AI skill, and is written as a plain Markdown file following the Muse Gadgets specification. The Skill is built around three design principles: single API key connectivity, direct cloud access through Tuya's cloud API, and reading each device's standardized Thing Model before generating commands. The Thing Model approach, the company disclosed, allows one Skill to cover a wide range of product categories without model-specific adaptation.

The filing describes a range of supported interactions. Users can control devices by voice-style requests such as dimming lights, check device status, list or rename devices in a room, receive condition-based alerts via SMS, voice call, email, or app push notification, capture camera snapshots or video up to 60 seconds, and set up automations triggered by device property changes or online and offline events. Real-time event subscriptions, according to the filing, require an always-online Linux device such as a Raspberry Pi running the Muse Gadgets Linux SDK.

The company disclosed several safety restrictions: the Skill writes only to properties of basic data types, stays strictly within value ranges defined by the Thing Model, does not write to read-only properties, and reports offline device status without issuing commands. After issuing a command, the Skill reads back device status one to two seconds later to confirm the change took effect. The API key is used only in request headers and, the filing states, "is never echoed in the conversation." The filing also notes that the company intends to advance the Skill in areas including camera visual understanding, energy-consumption analysis, and scenario automation templates, and characterizes these as forward-looking statements subject to its cautionary safe harbor language.
