Thinger.io Integration

The Milesight AM319L integrates with Thinger.io through LoRaWAN connectivity, enabling real-time monitoring and data visualization of indoor air quality parameters.

Requirements

A LoRaWAN server is required to communicate the Milesight AM319L 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 preference.

Usage

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

Use Cases

Offices: Monitor workspace air quality and occupancy
Stores: Track environmental conditions for customer comfort
Classrooms: Ensure healthy learning environments
Hospitals: Maintain optimal indoor air quality for patient care
Smart Buildings: Comprehensive environmental monitoring
