A set of two Shelly 1 Gen3 smart relays turns ordinary switches, sockets, and appliances into intelligent devices. Offers Wi‑Fi and Bluetooth connectivity, 1‑channel dry contact, up to 16 A, no HUB required, high security, and easy integration with Alexa, Google Home, and automation protocols. Ideal for lighting, garage doors, or irrigation – with remote control and flexible scenes.
The Shelly 1 Gen3 smart relay delivers powerful, reliable control for homes and offices. The new ESP‑Shelly‑C38F processor with 8 MB memory ensures fast response and stability, while the Wi‑Fi range extender and built‑in BLE gateway make pairing and device management across your home easier. Thanks to the dry contact and high current load up to 16 A, the relay is exceptionally versatile.
Integration is simple and requires no hub. The device works with the Shelly Smart Control app, supports MQTT, webhooks, and KNXnet/IP, so it easily fits into your scenes and automations. With compact dimensions, it fits standard wall boxes, and advanced encryption protects your data.
