1.2 Core Technology Layers

Layer	Responsibility	Technical Implementation
Perception layer	Acquire physical world state	IPC cloud snapshot + AI vision model
Decision layer	Convert fuzzy semantics to precise commands	Thing Model attribute parsing + value range mapping
Control layer	Precise device command dispatch	Tuya end-user API + multi-protocol compatibility
Feedback layer	Active notification of execution results	Multi-channel push (SMS / voice / email / App)

2. IPC Cloud Snapshot and Visual Perception

2.1 Technical Pipeline

The IPC visual perception module implements a complete loop from cloud snapshot to visual understanding:

User command → Agent locates IPC device → Dispatches snapshot/recording command
    → Device executes → Data uploaded to cloud storage
    → AI vision model analyzes → Structured result returned to Agent
    → Agent generates natural-language response

2.2 Capability Specifications

Capability	Specification
Photos	1–5 burst shots supported
Video	1–60 second short video recording
Storage	IPC cloud storage; data integrates seamlessly into AI workflows
Visual understanding	Connects to AI vision models; supports scene description, object recognition, and more

2.3 Technical Value

• Active perception: The Agent automatically completes the full loop — device location, command dispatch, image acquisition, and visual analysis — without manual user intervention
• Environment modeling: Visual data provides the Agent with physical-world context for decision-making
• Extensibility: Can be combined with wheeled mobile robots to enable inspection and proactive service scenarios

3. Intelligent Decision Engine

3.1 Thing Model-Driven Semantic Understanding

The Tuya Thing Model defines the complete attributes, states, and value ranges of a device. The Agent uses the Thing Model to:

Capability	Description
Attribute sensing	Read current device state (temperature, humidity, switch status, etc.)
Value mapping	Fuzzy semantics → precise parameters (e.g., "a bit hot" → decrease temperature by 2°C)
Range constraints	Valid value range validation based on the device’s Thing Model

3.2 Fuzzy Semantics to Precise Commands

Traditional IoT control requires users to specify exact parameters ("set the AC to 26°C"). tuya-smart-control enables the Agent to make autonomous decisions from context:

User input: "It's a bit hot"
    → Agent queries current room temperature: 30°C
    → Agent queries AC Thing Model: temperature range 16–32°C, current set point 28°C
    → Agent reasons: decrease 2°C → set to 26°C
    → Dispatches control command

4. Device Control Capabilities

4.1 Control Dimensions

Dimension	Capability
Attribute control	Switch, brightness, temperature, mode, color temperature, etc.
Spatial dimension	Three-level granularity: home / room / device
Batch operations	Cross-category, cross-room bulk command dispatch
Category coverage	3,000+ device categories with multi-protocol compatibility

4.2 Batch Control Execution Logic

User command: "Turn off all the lights and outlets"
    → Agent queries all rooms and device list
    → Filters target devices (category: lights + outlets)
    → Checks current device state (filters already-off devices)
    → Dispatches off commands in sequence
    → Aggregates execution results and returns feedback

The ability to aggregate logic across categories and rooms relies on the Tuya unified Thing Model system — no per-brand or per-protocol adaptation is required.

4.3 Feedback Channels

Channel	Use Case
App push	Command execution completion confirmation
SMS	Urgent notifications such as security alerts
Voice	Voice interaction device scenarios
Email	Periodic data statistics reports
Data statistics	Energy consumption, device history logs, etc.

5. Integration Architecture

5.1 Authentication

API Key format: sk-<PREFIX><rest>

The prefix automatically maps to one of the seven global data centers and is obtained based on the user’s account region:

Region	Endpoint
Mainland China	tuyasmart.com
International	tuya.ai

5.2 Integration Methods

OpenClaw Skill Integration

Install the tuya-smart-control Skill on the OpenClaw platform and configure TUYA_API_KEY — integration is complete. The Agent immediately gains IoT control capabilities.

CLI

# Authenticate
tuya-cli login --api-key sk-xxx

# List devices
tuya-cli devices list

# Control a device
tuya-cli device control <device_id> --property temperature=26

Python SDK

from tuya_api import TuyaAPI

api = TuyaAPI(api_key="sk-xxx")

# Query devices
devices = api.get_devices()

# Control a device
api.control_device(device_id, {"temperature": 26})

# IPC snapshot
image_url = api.capture_image(ipc_device_id, count=1)
