Shelly Relay 1PM Gen4 16A WLAN Zigbee Bluetooth — DIN-mount smart relay with power metering

Shelly Relay 1PM Gen4 is a compact DIN-mount smart relay designed for electrical control and energy monitoring in home and small commercial installations. The device offers a 16A switching capacity and integrated power metering, and supports multiple wireless protocols — WLAN, Zigbee and Bluetooth — enabling remote switching, load monitoring and integration with automation systems. Its DIN-rail format allows installation inside distribution panels and is intended for control of lighting, small electric appliances and circuits where space-efficient, metered switching is required.

Advantages

The relay combines a 16A switching capability with built-in power metering to provide both control and consumption data from a single compact module. Multi-protocol connectivity (WLAN, Zigbee, Bluetooth) supports flexible integration with a range of smart home hubs and direct control from mobile apps. DIN-rail mounting optimizes space in electrical cabinets and allows neat installation alongside breakers and other control gear. The device is suitable for remote switching, scheduling and measuring energy use for better load management.
