Control smartDEN IP-16R-MQ from Home Automation systems

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 which can run on servers based on Linux, macOS, Windows, Raspberry Pi, PINE64, Docker, Synology...

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

For Hardware configuration, please use: Type = Denkovi Modules with LAN (HTTP) Interface, Model = SmartDEN IP-16R-MQ

Please note you have to log-out from the webserver in order to access via Domoticz!



Access smartDEN IP-16R-MQ 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: MQTT and HTTP



Control smartDEN IP-16R-MQ with browser



Control smartDEN IP-16R-MQ via MQTT

smartDEN IP-16R-MQ relays can be controlled by MQTT V3.1.1 messages. The module subscribes to a topic like SmartDEN_MQTT16R/E8EADA123456/Set/RS1 and the publisher (laptop, smartphone) sends a message like 0 or 1 to turn ON and OFF the relay.




Control smartDEN IP-16R-MQ via HTTP GET Request and receive the reply in XML or JSON format

For software integrators - as usually, the module supports HTTP GET requests with JSON/XML reply.
