Thinger.io Integration

The Milesight AM308L seamlessly integrates with Thinger.io through LoRaWAN network servers, enabling real-time monitoring of indoor air quality parameters and automated data collection for analysis and visualization.

Requirements

A LoRaWAN server is required to communicate the Milesight AM308L 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

  • Office buildings: Monitor workspace air quality and occupancy
  • Educational facilities: Ensure healthy learning environments in classrooms
  • Healthcare facilities: Track environmental conditions in hospitals and clinics
  • Retail spaces: Monitor customer comfort and store conditions
  • Smart buildings: Integrate with building management systems for HVAC optimization
