Please access the HTMTL-5 based web interface of the monitoring unit only with Google Chrome, Apple Safari or Mozilla Firefox. Please check also if you have installed the recommended Java plugin. Try to delete the rule created under "Logical scheme" using your non-supported web browser. You may need to restart the IT monitor device before doing that. If the created logic can not be deleted, please initiate a reset to the factory settings via the DIP switch or use the CPU tool contained in the firmware file. After the monitoring system has been returned to default factory settings, please use only Chrome, Safari or Firefox for it`s configuration. Your IP-based remote monitoring unit should then work properly as usual.

You can deactivate the notifications and alarm rules by mouse click. To do this, go to the menu item "Logic schemes". Here you can enable or disable a.) all rules or b.) individual rules for a certain period of time. In your case select your alarm rule "Door contact server cabinet".

Under the item "Disable scheme" select "yes". Then set the period of deactivation. Here the IT monitoring & control device offers you for example a period of 10 minutes or even several hours. Then click on "Apply". The deactivated alarm rule is now displayed in red colour. After the time period has elapsed, the rule is automatically reactivated.

Please install the November 2020 firmware update on your Didactum measurement and telecontrol system. In the German web interface under "Logical Scheme" you will then find a new menu item "Activation / Deactivation of Logical Scheme" at the very top. Here, all rules and automatic actions will then be deactivated for a certain time (selectable from 10 minutes to a maximum of 24 hours).

IMPORTANT: Please note that this is a general / global function, which disables all notification and alarm functions of your server room monitoring system for a certain time! We explicitly warn against deactivating the alarm function of smoke detectors, power voltage detectors or water detectors installed in the server room! Of course, you can also deactivate the previously created monitoring functions and the associated alarm messages (access control / door contacts / vibration sensor / motion detector / automatic video transmission, etc.) individually.

We assume that you have stored individual threshold and alarm values for the SNMP-compatible temperature sensor in your smart monitoring system. For example, you have defined the temperature value of 24.5 degrees Celsius as the threshold / limit between the sensor states "Normal" and "Warning". If the temperature falls just below the value of 24.5°C, the temperature sensor state is considered to be "Normal". If the current temperature reaches a value just above 24.5°C, the "Warning" status is output.  In practice, it is often the case that the measured data fluctuates between the previously defined threshold values "Normal" and "Warning". In such a case, you would receive too many notifications and alarms from the smart measurement and monitoring system.


Simply use the hysteresis function offered by the monitoring systems. Using the hysteresis type "Time", you can for example define a required duration for the state change from "Normal" to "Warning" (and vice versa), you can for example store a duration of 1 minute before the monitoring system reports the new state as "Normal" or "Warning". If you use the hysteresis type "Value", the current sensor status will not be reported unless the temperature fluctuates by a larger (measured) value than previously defined in the monitoring system.

Currently you can define up to 500 different actions and alarms in the Didactum remote monitoring system.

After analyzing your configuration file, our technicians found that you have not defined any rules or automatic actions in the web interface under "Logical Scheme". These logics must be defined so that your network thermometer can notify and alert you and your colleagues in case of critical temperature in the server room. How to define notifications and alarms is described here.
