Thinger.io Integration
The WT304 integrates with Thinger.io through LoRaWAN connectivity, enabling remote monitoring and control of HVAC systems with centralized data collection and visualization.
Requirements
A LoRaWAN server is required to communicate the WT304 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 for remote thermostat control and monitoring.
