The Shelly Pro series are designed to be installed on the DIN rail in the breaker box, and are enhanced with temperature, overpower and over voltage load protection to ensure robustness of your Shelly ecosystem. The Shelly Pro 1 is a 1-channel smart switch and can be used to control anything from dynamic, motion-sensitive lighting to power-socket automation, cutting energy-hungry device's power at certain times to save on energy bills. The Shelly Pro 1 also fully supports mjS scripting which, when combined with Shelly's open API, allows you to write and customise scripts for your Shelly network to completely configure every part of your smart home, and dry contacts ensure the widest possible compatibility with a range of devices.
