Shelly 1PM Gen4 is a multiprotocol relay with power metering that wires behind a switch and speaks Wi-Fi, Bluetooth, Zigbee, and Matter, so it fits almost any smart home ecosystem.

Meters real power on the switched circuit and runs on whichever protocol the install uses. The native Shelly integration gives local Wi-Fi control with no cloud required, with Zigbee (ZHA or zigbee2mqtt), Matter over Wi-Fi, and MQTT as alternatives.
