Short Description
Shelly Shutter is a compact cover controller with power measurement, enabling remote control of shutters, shades, and blinds via mobile phone, tablet, PC, or home automation systems. It operates standalone on a local Wi-Fi network or through cloud-based home automation services. The device supports Venetian blinds.
Remote access is possible from anywhere with internet connectivity, provided the device is connected to a Wi-Fi router. It can be retrofitted into standard electrical wall boxes behind switches for covers.
The device features an embedded web interface for monitoring, control, and configuration of settings.
