Tuya Smart announced on November 13, 2026, the release of Tuya Cloud Devices, an open-source skill enabling Meta's personal AI agent Muse to query and control smart devices through Tuya's cloud using natural language and a single API key.

Key Highlights

  • New open-source skill released: Tuya Cloud Devices (skill name: gadget-tuya-cloud-devices) allows Meta's Muse AI agent to control smart home devices via Tuya's cloud, with no local device keys, shared network, 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 its next two characters identify the data center, enabling automatic selection from seven regional endpoints.
  • Platform scale: As of June 30, 2026, Tuya reported more than 2.09 million registered AI developers and coverage of over 3,000 categories of smart hardware across more than 200 countries and regions.
  • Safety boundaries built in: The skill does not write to read-only properties, withholds commands when a device is offline, keeps values within Thing Model-defined ranges, and spaces notifications triggered by device events at least 30 minutes apart.
  • Muse availability: According to the filing, Muse is currently available to users in the United States and Canada.
  • Skill portability: Originally developed for OpenClaw, the skill was adapted to the Muse specification and is designed to be reusable across multiple agents using the SKILL.md format.

Tuya Cloud Devices: How the Skill Connects Muse to Home Hardware

According to the announcement, Tuya Cloud Devices is derived from tuya-smart-control, described as Tuya's official open-source AI skill, and is structured as a Markdown file conforming to the Muse Gadgets specification. The skill is built on three design principles: single-key authentication, direct cloud access without requiring local device keys or same-network presence, and reading a device's standardized Thing Model before issuing any command. The filing states that if a device already has a model-specific or local-control skill, requests are routed to that skill first.

The filing describes a range of supported interactions, including direct device control, status queries, room and home management, sensor renaming, energy consumption history, camera snapshots returning images or video of up to 60 seconds, and real-time automation triggered by device-property or online/offline events. For event-driven automation, the announcement notes that an always-online Linux device capable of receiving event subscriptions is required, and that a connected Raspberry Pi can serve this role within the Muse Gadgets framework.

On security, the filing states that the API key is "treated as a credential," used only in request headers and "never returned in the conversation," and that it can access only devices linked to the user's account. The skill explicitly does not expose operations such as door-lock control, live video, firmware updates, network configuration, or device removal, directing such requests instead to the Tuya app. The announcement further states that Tuya's platform covers over 3,000 smart hardware categories and serves more than 200 countries and regions.

What Was Disclosed

Tuya Smart disclosed the release of an open-source AI agent skill enabling Meta's Muse to control Tuya-connected smart devices through the cloud, requiring only a single API key obtainable at tuya.ai, with no firmware changes or local network access needed.
