Shelly Gen4 1-Channel WiFi/Bluetooth/Zigbee 30Vdc Smart Relay
Shelly 1PM Gen4: Multiprotocol Smart Relay with Power Metering
The Shelly 1PM Gen4 lets you automate appliances and lighting while measuring their electricity consumption, providing convenient monitoring and control from a smartphone, tablet or computer. Its ultra-compact design makes it easy to install discreetly behind existing switches or sockets, upgrading a conventional electrical installation without changing its appearance.
This 1-channel smart relay operates from 110–240 V AC or 24–30 V DC and supports loads up to 16 A at 240 V AC or 10 A at 30 V DC. Its integrated power metering is particularly useful for monitoring the energy consumption of electric water heaters, lighting, portable heaters and other compatible appliances.
Its Gen4 multiprotocol architecture combines Wi-Fi 6, Bluetooth 5, Zigbee and Matter compatibility, making integration into different smart-home ecosystems easier. It is particularly suitable for installers looking for flexibility in home automation projects, whether for new installations or upgrades. It is not a dedicated replacement part, but a device designed to add smart control and power monitoring to new or existing installations.
The Shelly 1PM Gen4 allows existing physical switches to remain operational while adding smart control, automation and energy monitoring. A compact and versatile solution for expanding an installation with Shelly products and centralising the control of lighting and electrical loads.
