## Description

This is a two-pack of the Shelly 2PM Gen4, a 2 channel smart relay able to manage loads of up to 16A per channel with built-in power metering. Compact enough to retrofit pre-behind your light switch, socket, or behind any electrical appliance for easy, app-based remote control over standard WiFi, the 2PM Gen4 can also connnect over both Matter and Zigbee to be seamlessly adopted into pre-existing smart networks.

The Shelly 2PM Gen4 is able to control two different circuits of up to 16A via the free Shelly app or as part of a smart scene or schedule based on energy consumption or your daily routine. Its two channels makes it perfect for control of multiple electrical devices such as two separate lamps or heating units, or a single bi-directional motor (motorised blinds, garage doors and more).The compact design allows for easily instalation in tightly-packed junction boxes and behind pre-existing light switches.

This device also features precise power-monitoring capabilities, with the ability to measure the energy use of any device in which it's installed. These measurements can then either be stored locally in the device itself or securely in the cloud and accessed through the free Shelly app, offering a frictionless way to keep an eye on the energy usage of any smart devices.

The 2PM Gen4 is an update of the previous generation, the Shelly Plus 2PM Gen3, and features both an upgraded chipset and increased RAM to contribute to quicker operation and a suite of more sophisticated scripting capabilities. Each Gen4 device, including the 2PM Gen4, is also compatible out of the box with Zigbee and Matter in addition to WiFi and Bluetooth, meaning it can either connect instantly to a wider Shelly network across standard WiFi and Bluetooth, or be instantly adopted and integrated into a pre-existing Zigbee or Matter installation without requiring any expensive hubs or specific equipment.
