Shelly 1PM Gen4 WiFi & Zigbee Operated Relay with Power Metering

The Shelly 1PM Gen4 features a single channel and can manage loads of up to 16A, making it an ideal choice to 'smarten' pre-existing electrical devices in the home or the office. Requiring no specialised wiring or hubs, the 1PM Gen4 is designed to retrofit ordinary appliances by being installed in their electrical boxes or behind light switches, and can either operate in standalone mode to grant easy remote control over that device or as part of a fully customisable and intuitive smart schedule or scene involving multiple devices at once.

The 1PM Gen4 represents an advancement on the previous generation, the Shelly Plus 1PM Gen3, and incorporates a rich suite of new features and upgrades; in addition to an upgraded chipset and increased RAM to deliver quicker responsiveness and more sophisticated customisable scripting, each Gen4 device also supports both Zigbee and Matter in addition to the standard Bluetooth and WiFi. Each relay is capable of maintaining these different connections simultaneously, meaning the 1PM Gen4 can both connect to older Shelly networks via standard home and office WiFi, and pre-existing Zigbee or Matter networks without requiring an extra hub.
