Thinger.io Integration
The VS350 integrates seamlessly with Thinger.io through LoRaWAN connectivity, enabling real-time monitoring of people counting data and temperature measurements. The device supports automatic provisioning and provides structured uplink data for analytics and visualization.
Requirements
A LoRaWAN server is required to communicate the Passage People Counter 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.
Configure the device via NFC using the Milesight mobile app or through LoRaWAN downlinks. Set the reporting interval according to your use case requirements.
Usage
Start sending uplinks for autoprovisioning devices and buckets. This product provides predefined dashboards for visualizing people counting data, temperature trends, and traffic patterns. Historical data storage and retransmission features ensure no data loss even during temporary connectivity issues.
