Long range wireless switch

LoRa Long Range Wireless Switch — Control Appliances Without GSM or WiFi

The REACT-L-SC is a long-range wireless switch system for controlling appliances over LoRa radio — without needing GSM, WiFi, or any internet connectivity. A SWITCH transmitter sends the command; a CONTROLLER receiver at the appliance acts on it. Range extends to several kilometres in open terrain.

How It Works

The system has two parts: a handheld or wall-mounted SWITCH and a CONTROLLER unit wired to the load. Pressing the SWITCH sends a LoRa signal directly to the paired CONTROLLER — which toggles the relay output. No gateway, no cloud, no app required. Point-to-point control over long distances.

Use Cases

• Remote pump control — switch a borewell or irrigation pump from a farmhouse without running control cables across the field
• Gate and shutter control — open a remote gate or rolling shutter from a distance where WiFi doesn't reach
• Rural and agricultural automation — control motors, valves, and lighting in locations with no internet or mobile coverage
• Industrial yards — operate equipment at distance within a plant or logistics yard without radio licence (sub-GHz LoRa)

Key Specifications

• Radio: LoRa (sub-GHz, long range)
• Infrastructure required: None — direct point-to-point, no gateway or internet
