🪟 Shelly Yihao - YH002-A: Smart Motor for Your Blinds
Shelly Shelly Yihao YH002-A is a practical smart controller that automates your existing chain-operated blinds quickly, efficiently, and without investing in a new system. Mount this controller onto your existing chain in a few minutes to instantly transform traditional roller blinds, Roman shades, zebra blinds, vertical blinds, and Venetian blinds into smart window coverings.
Thanks to built-in Wi-Fi and Bluetooth connectivity, you don't need any additional hub or gateway – control your blinds immediately directly via the Shelly Smart Control app. Simply attach it, insert the chain, and you have immediate control in your hands – via smartphone, Shelly BLU remote control, or voice assistant.
It offers precise calibration with millimeter adjustments for upper and lower limit positions, which remain saved even during power outages. The device integrates fully into the Shelly ecosystem, unlocking advanced automation, time scheduling, scene creation, or custom JavaScript scripts. It is an ideal choice for single-window automation, yet easily handles complex shading control for an entire home, office, or commercial building, delivering hassle-free comfort, energy savings, and privacy.
It can automatically follow sunrise and sunset times, respond to room temperature and sunlight intensity, and collaborate with Shelly sensors, weather stations, presence detectors, and remote controls to create smart shading scenarios. This helps reduce overheating in summer and supports passive solar heating during winter. The system also enhances privacy and security through presence-based automation and vacation mode simulation.
Integration with Home Assistant, MQTT support, REST API access, and local control make it suitable for both beginners and advanced smart home installations.
