Shelly Pro 2PM – DIN-rail mounted 2-channel smart switch with power metering

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 2-channel smart switch with power metering. Thanks to the flexibility of the Gen2 firmware and its LAN connectivity, it gives professional installers more solutions to offer end users. The device can work standalone on a local Wi-Fi network or via the cloud with home automation services.

Shelly Pro 2PM 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 2PM has a built-in web interface for monitoring, controlling and configuring the device.
