Superior home and building automation with Shelly's professional line of smart switches

Enhanced with temperature, overload and overvoltage protection, the Shelly Pro series is designed for installation in a DIN electrical cabinet. It enables complete smart automation without additional cabling or wiring, making it ideal for homes, offices, shops, businesses, manufacturing plants and even new builds.

DIN rail mounting

The Shelly Pro range is designed for installation in the electrical cabinet and complies with worldwide DIN rail standards. This makes it suitable for all types of installations and allows easy installation without additional components.

No central controller required

Shelly Pro devices can be controlled directly and without a gateway (hub) via your smartphone using the Shelly Cloud app.

Manage and control all the smart devices in your home, set up quick profiles, scenarios, schedules and adjust settings wherever you are - via the cloud or just a local connection!
