The Shelly Yihao Blinds Chain Controller YH002-A is a retrofit smart blind motor designed to automate existing chain-operated window coverings without replacing the entire shading system. The motor can be installed on the existing control chain within minutes, enabling traditional roller blinds, Roman blinds, zebra blinds, vertical blinds, and Venetian blinds to gain smart control capabilities. Thanks to built-in Wi-Fi and Bluetooth connectivity, no separate hub or gateway is required, and control is available directly through the Shelly Smart Control app.
The system supports precise end-position calibration, allowing opening and closing positions to be configured with millimeter-level accuracy. These settings are retained even after power outages. As part of the Shelly ecosystem, it offers extensive automation capabilities, including schedules, scenes, local automations, and JavaScript-based scripting support. The device is suitable for automating a single window covering or managing the shading system of an entire home, office, or commercial space.
The Yihao YH002-A can automatically follow sunrise and sunset times, react to room temperature and sunlight intensity, and cooperate with Shelly sensors and weather stations. This helps reduce overheating during summer and supports passive solar heating during winter. The system can also enhance privacy and security through presence-based automations and vacation mode simulations.
The Shelly Yihao Blinds Chain Controller integrates seamlessly with the Shelly ecosystem and supports advanced automation workflows. It can work together with Shelly sensors, weather stations, presence detectors, and remote controls to create intelligent shading scenarios. Home Assistant integration, MQTT support, REST API access, and local control make it suitable for both beginner and advanced smart home installations.
Example Use Cases
- Natural wake-up: Gradual blind opening at sunrise to let natural light enter the room
