DAEnetIP4 - SNMP Ethernet controller with 34 digital/analog I/O

DAEnetIP4 is the next generation multifunctional 10/100 Mb Ethernet device (IP controller) for management and control. It has the usual features we offer for such products like web server, snmp, http/xml, traps and analog/digital i/o. In addition this successor of DAEnetIP1 has some other features like Real Time Clock weekly schedule, 8 x 16 bit counters, 2 x 10 bit PWM channels and standalone work improvements. It is to be used for embedding in other systems (plug-in type) and could be used for industrial and home automation, access control, fire and security, irrigation systems, dimming lights and others. Supported by DRMv3 software. Works with Home Assistant, Domoticz and OpenHAB home automation systems as well as with Node-RED IoT platform. Now with FREE Android and iOS App!

DAEnetIP4 Overview



Access from Home Assistant

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





Access DAEnetIP4 from OpenHAB

OpenHAB is a third party open source free home automation software. Run your server on Linux, macOS, Windows, Raspberry Pi, PINE64, Docker, Synology... Access it with apps for the web, iOS, Android and others. Use a powerful and flexible engine to design rules, with time and event-based triggers, scripts, actions, notifications and voice control.


There are two ways of communication - via SNMP and HTTP GET requests. More information about the integration with our hardware - or contact with us.




Access DAEnetIP4 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.

The video bellow shows how you can control DAEnetIP4 based device - Internet/Ethernet 12 Channel Relay Board. Any other Denkovi Ethernet Device from this list can be acessed with same success from your iOS device via DAE-iModules.


Some useful information:

  • Select device DAEnetIP4. Enter the IP address (URL), UDP Port and SNMP Community for the device;


Control DAEnetIP4 with browser


Access via software DRMv3

This device is supported by DRMv3 Software.

The device can be found in the device list under the default name: DAEnetIP4








Control DAEnetIP4 via JSON/XML/HTTP GET requests


Control DAEnetIP4 via command line

Net-snmp is free command line utility for windows which allows you to execute snmp commands from command line, BAT files, BASH scripts or any other sofwtare that can execute external .exe file or commands from command line. The instructions file how to install net-snmp and example commands can be downloaded from here.

  • Problem: There is an access to the device via SNMP, PING and Denkovi Finder "see" it, however it is not possible to open it's web server via any browser (the HTTP port is correct as well).
  • Solution: Some antivirus software (like Avast for example) may block the HTTP traffic to the device. Be sure this type of communication is enabled by your antivirus/firewall software.
