Waveshare Cloud Configuration

Create Device

Waveshare Cloud provides exclusive device control examples for Modbus POE ETH Relay, and you can start by quickly creating devices.

Quick Start

The platform supports one-click quick start, go to Device Management ->Device List ->One-click Add:

Detailed Steps (Skip to Device Settings for Quick Start)

When creating device properties, you can choose the HEX character type, enter the hex value of the corresponding switch, and select to display the chart

Device Settings

Open VirCom to configure device MQTT connection properties. Please note that if the device has already been configured with some information, it is recommended to load default parameters and restart the device before configuring, for example:

For the modified device, go to Firmware and Configuration

Copy the device subscription address parameters of Waveshare IoT and fill them into the settings, save and download, and wait for a prompt indicating successful transmission

View the TCP connection in Device Management to see if the cloud device is online by displaying established connections

Device Control

Go to the console, view the device, and enter development

Enter the device details page to view the switch-type devices, click the button to set the status of the terminal hardware device

At this time, we check the trigger status of the Modbus PoE ETH Relay relay. Here, CH1 corresponds to relay 0, which is the relay set in the cloud
