Thinger.io Integration
The WT101 Smart Radiator Thermostat integrates seamlessly with Thinger.io through LoRaWAN® connectivity, enabling remote monitoring of temperature readings, valve positions, battery status, and heating schedules. The integration supports bidirectional communication for adjusting heating plans and thermostat settings remotely.
Requirements
A LoRaWAN server is required to communicate the WT101 Smart Radiator Thermostat 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.
