Shelly BLU Gateway Bluetooth to Wi-Fi Smart Home Bridge USB Dongle
The Shelly BLU Gateway is a compact USB-A dongle that bridges your Shelly BLU Bluetooth devices to your Wi-Fi network and the Shelly Cloud, eliminating the need for expensive upgrades to Plus or Pro devices. This smart gateway receives Bluetooth Low Energy (BLE) signals from compatible Shelly sensors and devices, then transfers them to the cloud or locally to other non-Bluetooth devices in your smart home ecosystem. Perfect for integrating Gen-1 Shelly relays with the latest BLU sensors, the gateway supports MQTT, WebSocket, and popular home automation platforms like Home Assistant, giving you flexible local and cloud control options. Measuring just 45 × 20 × 8mm and weighing only 5 grams, this plug-and-play dongle revolutionises your smart home setup without complex wiring.
