Thinger.io Integration

The LTC2 Temperature Transmitter integrates seamlessly with Thinger.io through LoRaWAN network servers, enabling real-time temperature monitoring, data logging, and alarm management for industrial applications.

Requirements

A LoRaWAN server is required to communicate the LTC2 Temperature Transmitter into Thinger.io, some options are:

Alongside, the corresponding plugin for the selected LoRaWAN server needs to be installed in your Thinger.io instance.

Get Started

Installation

Look for the plugin in the Thinger.io Plugin Store and install it in your Thinger.io instance. Once the plugin is installed a new Product will be created for this device.

Configuration

The Product is already preconfigured, check that the auto provision prefix matches the one selected in your LoRaWAN server plugin in Thinger.io, or change it to your desire.

Usage

Start sending uplinks for autoprovisioning devices and buckets. This product also provides a predefined dashboard and downlinks.

Use Cases

  • Industrial temperature monitoring
  • Food safety temperature control
  • Cold chain monitoring
  • HVAC system monitoring
  • Process control applications
  • Environmental monitoring
