Device identification

• Device name: Shelly Pro 2 v.1

• Device model: SPSW-202XE16EU

• Device SSID: ShellyPro2-XXXXXX

Short description
Shelly Pro 2 is a DIN rail mountable 2-channel smart switch with potential-free contacts. Thanks to the flexibility of its Gen2 firmware and LAN connectivity, it gives professional installers more options for end-user solutions. The device can work standalone on a local Wi-Fi network or via the cloud with home automation services.

Shelly Pro 2 can be accessed, controlled and monitored remotely from anywhere with an internet connection, as long as the device is connected to a Wi-Fi router and the Internet.

Shelly Pro 2 has a built-in web interface that can be used to monitor and control the device and adjust its settings.
