Easily access SmartDEN IP-16R-MT via internet or LAN and control appliances remotely for Home Automation and Industrial Automation applications.

SmartDEN IP-16R-MT supports up to 30 schedule events for controlling appliances without connection with computer. It is possible to set ON/OFF event upon minute, hour, day of week or certain date. For more information please take a look into the documentation.

SmartDEN IP-16R-MT supports periodically sending outgoing ping request to remote host (router, switch, PC, IP camera...) and upon timeout it will perform reboot of the device in order "to keep it alive".

Android App DAE-aModules

Some useful information about DAE-aModules and smartDEN IP-16R-MT:

• Select device smartDEN IP-16R-MT - XML. You have to enter the IP of the device, the HTTP (Web) port and the main password (so far it is implemented only the HTTP/XML communication with the android app).

Please note you have to log-out from the webserver in order to work with the android app!

This device is supported by DRMv3 Software.

The device can be found in the device list under the default name: smartDEN IP-16R-MT

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

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 HTTP GET and ModBus-TCP requests. More information about the integration with our hardware - http://denkovi.com/openhab-with-denkovi-modules or contact with us.

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

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
