Milesight UC51x Series LoRaWAN® Solenoid Valve Controller

The Milesight UC51x series is a LoRaWAN® wireless solenoid valve controller used to remotely control DC latching solenoids of the valve. It contains 2 solenoid interfaces and 2 GPIO interfaces, which can be easily controlled locally or remotely. Besides ultra-low-power LoRaWAN® technology, UC51x series also provides built-in solar panel and high-capacity battery power supply for long-term operation. For outdoor applications, it equips with IP67-rated enclosure and M12 connectors to protect from water and dust under harsh environments.

Thinger.io Integration

The Milesight UC51x Series integrates seamlessly with Thinger.io through LoRaWAN® connectivity, enabling remote monitoring and control of solenoid valves, flow data collection, and automated irrigation management.

Requirements

A LoRaWAN® server is required to communicate the Milesight UC51x Series 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 valve control and monitoring.
