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

smartDEN IP-Maxi 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, as well as to monitor/control input/output channels. Supported by DRMv3 Software. smartDEN IP-Maxi provides both SNMP 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.

Brand: Denkovi Assembly Electronics ltd.

Code: smartDEN IP-Maxi-12V

Sensors

smartDEN IP-Maxi is shipped with one NTC thermistor (temperature) sensor B57500M Epoxy Resin (up to 4 such sensors are supported by singe module). However additional sensors can be ordered from our store from these links:

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

Application Examples

Example 1. Controlling electrical appliances remotely

Example 2. Monitoring sensors online

Example 3. Controlling electrical devices depending on sensors values automatiacally (PC used only for configuration)

Example 4. Web based thermo-regulator

Example 5. smartDEN IP-Maxi has the unique capability to act like "differential" thermoregulator (control relay depending on two analog inputs values difference)

Example 6. smartDEN IP-Maxi used in application for counting customers in shops

Example 7. smartDEN IP-Maxi analog outputs can be used for diming led lights (not directly, but using led driver 0/1 - 10V)

smartDEN IP-Maxi overview

Access from Home Assistant

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

Access smartDEN IP-Maxi 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 SNMPv1 and HTTP GET requests. More information about the integration with our hardware - http://denkovi.com/openhab-with-denkovi-modules or contact with us.

Access smartDEN IP-Maxi 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.

Access smartDEN IP-Maxi from Node-RED

You can download the example Node-RED flows from here: SNMP and HTTP

Access smartDEN IP-Maxi from mobile devices

iOS App DAE-iModules

Android App DAE-aModules

Some useful information:

Select device smartDEN IP-Maxi. Enter the IP address (URL), UDP Port and SNMP Community for the device;

Access via software DRMv3

This device is supported by DRMv3 Software.

The device can be found in the device list under the default name: smartDEN IP-Maxi

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.

Access smartDEN IP-Maxi from browser

Control smartDEN IP-Maxi via JSON/XML/HTTP GET requests

Control smartDEN IP-Maxi 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.

Troubleshooting

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.
