Shelly BLU Gateway is a Bluetooth WiFi gateway in a USB-A dongle. A dongle that acts as a bridge between your Shelly BLU devices and the wider Shelly ecosystem. It receives Bluetooth signals and sends them to the cloud or locally to another non-Bluetooth device. Now all your Shelly devices - not just Plus and Pro - can seamlessly interact with your BLU devices. EXTEND YOUR EXISTING WiFi RANGE - In many homes, a single router is too weak to produce a stable signal that reaches every room, resulting in dead zones and faulty connections. With the Shelly BLU Gateway you can transmit your signal up to 30 m indoors and up to 50 m outdoors. UNIT YOUR SMART DEVICES - IN THE CLOUD OR LOCALLY - Shelly BLU Gateway is a small USB dongle that serves as a gateway between Shelly BLU devices and the Shelly Cloud. If you want to use Shelly Gen-1 devices with Shelly BLU sensors, Shelly BLU Gateway can serve as a gateway to the Shelly Cloud and thus to your existing Gen-1 devices. SHELLY CUSTOMER
