Shelly Pro 2PM – DIN rail-mounted dual-channel smart switch with current consumption measurement

Device identification

• Device name: Shelly Pro 2PM v.1

• Device model: SPSW-202PE16EU

• Device SSID: ShellyPro2PM-XXXXXX

Short description
Shelly Pro 2PM is a DIN rail-mounted dual-channel smart switch with power measurement capability. Thanks to gen2 firmware flexibility and LAN connectivity, it offers more solutions for professional installers and end users. The device can operate independently in a local Wi-Fi network or through cloud with home automation services.

Shelly Pro 2PM can be accessed, controlled and monitored remotely from any internet-connected location when the device is connected to a Wi-Fi router and the Internet.

Shelly Pro 2PM has a built-in web interface through which the device can be monitored, controlled and configured.
