Thinger.io Integration

The WT401 integrates with Thinger.io through LoRaWAN, enabling remote monitoring and control of HVAC systems with real-time data visualization and advanced scheduling capabilities.

Requirements

A LoRaWAN server is required to communicate the WT401 into Thinger.io. Compatible options include:

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. Verify that the auto-provision prefix matches the one selected in your LoRaWAN server plugin in Thinger.io, or adjust it as needed. Configure the device using NFC or Bluetooth for quick setup.

Usage

Start sending uplinks for autoprovisioning devices and buckets. The device reports temperature, humidity, PIR occupancy status, target temperatures, control modes, fan modes, and battery level. This product supports predefined dashboards and downlinks for remote thermostat control including temperature setpoints, control modes, and fan settings.
