Shelly 2PM Gen3 set of 2 smart dual-channel Wi‑Fi/Bluetooth relays

A set of two Shelly 2PM Gen3 smart relays brings a dual channel, energy metering, and blind and shutter control from anywhere over Wi‑Fi and Bluetooth. Thanks to its compact size, it fits standard in-wall boxes, supports automation and scripting, works as a Wi‑Fi extender and BLE gateway, and offers advanced protections for safe operation.

Shelly 2PM Gen3, in a pack of 2, is a universal dual-channel relay with precise per‑channel energy monitoring. Easily automate lighting, appliances, and bidirectional motors (blinds, shutters, awnings) with Cover Control, including obstacle detection and fine adjustment of the slat angle. Stable operation is ensured by the modern ESP‑Shelly‑C38F and 8 MB flash.

The device supports Wi‑Fi 802.11 b/g/n and Bluetooth 4.2, can act as a Wi‑Fi range extender and BLE gateway, improving coverage in larger spaces. With webhooks (up to 20, each with up to 5 URLs), scripting, MQTT, HTTPS/TLS, and KNXnet/IP, you can easily integrate it into your smart home. Protections against overheating, overvoltage, overload, and excessive consumption increase safety.
