Thinger.io Integration

The CT310 seamlessly integrates with Thinger.io through LoRaWAN connectivity, enabling real-time monitoring of current consumption, cumulative energy data, and temperature readings via customizable dashboards.

Requirements

A LoRaWAN server is required to communicate the CT310 into Thinger.io. Compatible options include:

The corresponding plugin for the selected LoRaWAN server must 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 preference.

Usage

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