Introduction

Create a private IoT network for under $100. No cloud fees, full data privacy. The DFRobot LoRaWAN Indoor Gateway (US915) is a comprehensive solution for home automation enthusiasts and IoT developers. Unlike traditional gateways that rely on external clouds, this device features a Built-in SIoT Local Server and Pre-installed Node-RED. Powered by a Quad-core Cortex-A35 processor and the high-performance Semtech SX1302 8-channel chip, it enables data collection from outdoor sensors (up to 4km range) with local processing. This architecture ensures data safety, facilitates home automation, and eliminates monthly subscription costs.

LoRaWAN Gateway Local Server - Privacy, Speed, and Reliability.

Most gateways act as simple bridges to the internet. The DFRobot Gateway operates as a standalone processing unit.

Total Privacy: Camera feeds, moisture levels, and location data never leave the local network.

Zero Latency: Local processing ensures instant response times for automations.

No Cloud Fees: Eliminates subscription services for data hosting.

Offline Operation: Smart garden or security systems continue functioning even without an internet connection.

Automate with Built-in Node-RED

Zero-Code Logic for Everyone. Building complex IoT systems does not require programming expertise. The industry-standard visual programming tool, Node-RED, comes pre-installed on the device.

Scenario: Smart Irrigation

Hardware: Gateway + Control Terminal

Logic: Connect a soil sensor to the Terminal's RS485/Analog port. Connect a water valve to the Relay port.

Node-RED Flow: Configure the Gateway to read sensor data -> If moisture < 20% -> Send Downlink command to open Relay.

High-Performance Hardware

Semtech SX1302 8-Channel Chip: Handles dozens of sensors simultaneously with high sensitivity (-140dBm).

Quad-Core CPU: Powerful Cortex-A35 processor (1.3GHz) ensures Node-RED flows run smoothly without lag.

Auto Data Parsing: Automatically converts raw hex data into readable values (e.g., converting 0x1C to 28°C).
