KNOT LR9G kit
An industrial-grade IoT gateway for smart asset tracking, remote monitoring, and efficient automation – now with enhanced LoRa® reception, concurrent GPS + LTE CAT-M, and a lower price. This is the 915 MHz version.
Smart IoT Connectivity That Just Works
The KNOT LR9G is a compact, out-of-the-box gateway for LoRa®-based networks, designed to bring affordable, reliable connectivity to even the most remote or infrastructure-light environments. It supports LTE CAT-M1 and NB2, Bluetooth 5.2, 2.4 GHz Wi-Fi, GPS, and Ethernet with PoE, making it a flexible centrepiece for any IoT deployment.
CAT-M1 and NB2 mobile internet connectivity allows you to save tons of money and remotely monitor and manage equipment without needing high-cost data plans or full LTE coverage.
Whether you’re tracking high-value assets across a hospital, managing a vending machine in a shopping mall, or monitoring sensors in an agricultural field – the KNOT LR9G ties everything together and keeps everything connected.
Key Features & Upgrades
Practical Use Cases
Hospital Asset Tracking
Attach Bluetooth beacons to critical medical equipment. Install a KNOT LR9G in each storage area. As gear moves, KNOT detects nearby tags, tracks location via GPS, and sends updates over LTE CAT-M – keeping inventory up-to-date and reducing manual audits.
Cold Chain Monitoring
Use wired Modbus sensors to monitor temperature and humidity inside refrigerated containers. KNOT converts Modbus to TCP and forwards data securely via MQTT or HTTPS, using low-bandwidth LTE or NB-IoT
Agriculture & Remote Sites
Deploy KNOT to gather soil or weather sensor data in rural fields. Its wide band support, LoRa® reception, GPS compatibility make it ideal for long-range, low-power data collection.
Industrial Automation
Bridge legacy wired sensors and actuators to the cloud. With DIN rail support and GPIO monitoring, KNOT easily integrates into industrial cabinets or manufacturing environments
Lightweight, Powerful, Cost-Effective
At just 6W consumption and small footprint (122 × 87 × 26 mm), the KNOT LR9G is perfect for deployments where space, power, and budget are limited – but performance can’t be.
Track, monitor, automate – smarter and cheaper than ever before.
