smartDEN Maxi IoT - I/O Relay Module MQTT, HTTP with DIN RAIL BOX

smartDEN IP-Maxi-MQ is an Ethernet module (IP controller) that can be used in a wide range of remote sensors monitoring, home automation control, environmental monitoring and data-acquisition applications. Thank to its multi-channel design (8 digital inputs, 4 analog inputs, 4 temperature inputs, 8 SPDT relays and 2 analog outputs) this device can perform simultaneously a variety of measurement and control functions. The Web interface allows users to configure the smartDEN IP-Maxi-MQ, as well as to monitor/control input/output channels. Supported by DRMv3 Software. smartDEN IP-Maxi-MQ provides both MQTT and XML/JSON interface for integration with third-party developed applications. Works with Home Assistant, Domoticz and OpenHAB home automation systems as well as with Node-RED IoT platform.

The module has 4 analog inputs 0-10V which can be used also with every analog output sensor within this voltage range. You can check our other sensors as well for the analog inputs: LM35DZ (temperature), LM335Z (temperature), HIH-4000 (humidity), TSL250R (light), GP2Y0A21YK (proximity), Voltage Transducer 0-300V AC In, 0-10V DC Out, Current Transducer 0-50A AC In, 0-10V DC Out

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 - 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 (HTTP) Interface, Model = SmartDEN IP-Maxi

 

 

Access smartDEN IP-Maxi-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

The device can be controlled by smartDEN IP-32IN Input Module over the network

This is the so called BOX-TO-BOX mode. An input from smartDEN IP-32IN Input module can control over the network (ethernet/internet) relay from current module. Meantime it is also possible to control the relays and inputs from mobile devices, web browser... Please check out our application note DAE-AN016 for more information.

 

 

Control smartDEN IP-Maxi-MQ via MQTT

smartDEN IP-Maxi-MQ relays can be controlled by MQTT V3.1.1 messages. The module subscribes to a topic like SmartDEN_MQTTMaxi/E8EADA123456/Set/RS1 and the publisher (laptop, smartphone) sends a message like 0 or 1 to turn ON and OFF the relay. For full MQTT commands list, please refer to the product documentation.

 

 

 

Access smartDEN IP-Maxi-MQ from browser

 

 

Control smartDEN IP-Maxi-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.

smartDEN IP-Maxi-MQ HTTP GET request concept

Sample JSON GET request:

http://192.168.1.53:31080/current_state.json?pw=admin&Relay1=1

Sample XML GET request:

http://192.168.1.53:31080/current_state.xml?pw=admin&Relay2=0

Please refer to the documentation for more information what is the command format and what parameters are supported.

XML and JSON GET request / reply

Troubleshooting

  • Problem: There is an access to the device via 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.
