Control from Denkovi Wi-Fi 16 Relay TCP Modbus App
This is free software for easy configuration/monitoring/control the Wi-Fi 16 Relay Module.
Control from Android mobile apps
The Wi-Fi 16 Relay Module can be controlled/tested easily with DroidBus Android app
Control from iOS mobile apps
The Wi-Fi 16 Relay Module can be controlled/tested easily with Modbus Peek & Poke
Control from Windows
Packet Sender is also very useful tool for TCP/UDP packets sending. It supports GUI but there is also command line interface (CLI) which allows the relays to be controlled from command line
Controlling from command line console is also very easy. Here we have prepared some example commands for turning ON/OFF relays - download.
Configuration via Web Browser
The built-in web server provides ability for basic configuration of the module, like network settings, TCP/IP and UDP sockets parameters, wireless settings, passwords. Please note the relays can not be controlled via the web server!
