Short description

Shelly Pro 1 is a DIN rail mountable smart relay with potential-free contacts. Enhanced with all the gen2 firmware flexibility and LAN connectivity, it provides professional integrators with many more options for end customer solutions. It can work standalone in a local Wi-Fi network or it can also be operated through cloud home automation services.

Shelly Pro 1 can be accessed, controlled and monitored remotely from any place where the User has internet connectivity, as long as the device is connected to a Wi-Fi router and the Internet.

Shelly Pro 1 has an embedded Web Interface which can be used to monitor and control the device, as well as adjust its settings.
