Shelly 2PM Gen4 — Dual Relay WiFi+Zigbee with Energy Meter

Shelly 2PM Gen4 — Dual WiFi+Zigbee Relay with Power Meter

The Shelly 2PM Gen4 (model S4SW-002P16EU) is a two-channel relay with energy metering and multi-protocol connectivity: WiFi, Zigbee 3.0, Bluetooth BLE, and Matter. It controls two circuits independently, monitors per-channel consumption in real time, and automates blinds, awnings, or motors from any device. No hub or subscriptions required.
