Thinger.io Integration

The Milesight TS301/TS302 can be integrated into Thinger.io through a LoRaWAN network server, enabling remote temperature monitoring, data visualization, and automated alerts.

Requirements

A LoRaWAN server is required to communicate the Milesight TS301/TS302 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.
