Device identification

  • Device name: Shelly Pro 3

  • Device model: SPSW-003XE16EU

  • Device SSID: ShellyPro3-XXXXXX

Short description

Shelly Pro 3 is a DIN rail mountable 3-channel smart relay with potential-free contacts, capable of switching 3 completely independent circuits, including 3-phase ones. 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 3 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 3 has an embedded Web Interface which can be used to monitor and control the device, as well as adjust its settings.
