Application Examples

  • Home Automation
  • Industrial Automations
  • HVAC

 

Overview

 

 

Supported ModBus TCP commands

  • Read Coils (0x01)
  • Write Single Coil (0x05)
  • Write Multiple Coils (0x0F)
  • Write Single Holding Register (0x06)
  • Read Multiple Holding Registers (0x03)

  • Report Slave ID (0x11)

Warning: please note it is not possible to connect multiple devices from this type in single modbus network. This means the computer/smartphone is the master and the only Wi-Fi 16 Relay Module - TCP Modbus is the slave.

 

 

Access from Home Assistant

Home Assistant is very powerful home automation system. Please checkout our application note for more information.

 

 

 

Access from OpenHAB

OpenHAB is a third party open source free home automation software.

There are two ways of communication - via ModBus-TCP requests. More information about the integration with our hardware - http://denkovi.com/openhab-with-denkovi-modules or contact with us.

 

 

 

Access from Domoticz

Domoticz is a free open source popular home automation software which can run on Windows, Linux, MAC, Rasberry PI and others. It is a home automation system design to control various devices and receive input from various sensors. Access it with apps for the web, iOS, Android and others.

 

More information about how to connect and use it with our hardware - http://denkovi.com/domoticz-with-denkovi-modules or contact with us.

For Hardware configuration, please use: Type = Denkovi Modules with LAN (TCP) Interface, Model = WiFi 16 Relays-TCP Modbus, Slave ID = 1

 

 

 

Access from Node-RED

Node-RED is a flow-based programming platform for the Internet of Things. We prepared small example for communication between Node-RED and our device. More info about Node-RED and denkovi modules: here

You can download the example Node-RED flows from here: ModBus-TCP

 

 

 

Access via software DRMv3

This device is supported by DRMv3 Software.

The device can be found in the device list under the default name: Wi-Fi 16 Relay ModBus TCP

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 iOS mobile apps

The Wi-Fi 16 Relay Module can be controlled/tested easily with Modbus Peek & Poke

 

 

Control from Windows

The Wi-Fi 16 Relay Module can be controlled/tested easily with Modbus Poll. Download the mbp description file for Holding Registers.

 

 

 

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!
