Shelly Shutter is a compact Wi-Fi controller for a compatible single-phase bidirectional AC motor used with blinds, shutters or curtains. It measures power, supports position and Venetian-blind slat control after correct setup, and can operate locally or through Shelly services. Bluetooth is used for commissioning rather than direct control. The motor must have suitable mechanical or electronic limit switches.

Installation should be carried out by a qualified electrician, who must confirm the supply, wiring and connected load are suitable.
