Smart Home IoT Gateway with Sub-GHz, BLE, Wi-Fi

Droid Technologies designed and developed a smart home IoT gateway that connects local sensors, actuators, and automation devices with cloud services through multiple wireless communication protocols.

The gateway supports Sub-GHz communication with a custom RF protocol for reliable long-range connectivity with distributed smart home nodes. Bluetooth Low Energy (BLE) is used to communicate with local devices such as temperature and humidity sensors, smart dampers, and other wireless peripherals.

For cloud connectivity, the gateway uses Wi-Fi with secure MQTT and HTTPS communication, enabling integration with AWS cloud services for remote monitoring, device control, telemetry, and automation.

Droid Technologies delivered hardware design, PCB development, embedded firmware, RF integration, wireless protocol development, cloud connectivity, and complete system integration.
