Logging function

For each temperature measurement, the measured values are stored in the memory with the associated time stamp. At a measuring interval of one minute, data can be stored for one month, which corresponds to approx. 44,000 measurements. If the memory is full, the oldest values are overwritten.

Indicator

The device has a button and a multicolored LED for operation and display of the operating status. The button is used when the device is put into operation or to switch off the logging process in battery mode. The LED indicates the device status and whether a valid measurement was performed in the current measurement interval and the data could be sent to the monitoring system.

Push-button

The device is controlled and configured via a server application. When a device is integrated into a system, the user must confirm he is the owner of the respective device by pressing on a key.

Whether a device is integrated in the system or is primarily stored on the server. However, the device retains this information each time it communicates with the server and maintains the state in the event of a reboot or loss of connection. To remove the device from the system, it must be deleted from the server.

The push-button can be used to unpair as well.

RTCC (Real Time Clock Calendar)

The device is equipped with a real time clock. The time is continuously synchronized if there is a connection to the server.
