Shelly 2PM GEN4

Product Introduction

The Shelly 2PM Gen4 is a compact dual-channel smart relay with integrated power monitoring designed to automate and control two electrical circuits independently. Installed behind wall switches, sockets, or inside electrical junction boxes, the device allows users to remotely manage appliances, lighting, or motorised systems while monitoring real-time energy consumption. 

The Gen4 generation introduces multiprotocol connectivity, enabling the device to operate using Wi-Fi, Zigbee, Bluetooth, or Matter. This allows seamless integration with a wide range of smart home ecosystems while giving users flexibility to choose the communication protocol that best suits their installation.

In addition to controlling two independent circuits, the relay also supports cover control, allowing automation of roller shutters, blinds, curtains, and other bi-directional AC motors. With built-in power measurement on each channel, homeowners can track energy usage and optimise electricity consumption across connected devices.

Key Features
