The page with device data contains information about data in Open4Tech. The page includes several sections:
- Device Data – contains last-ended data by location, type and device settings.
- Device Data Chart – Contains last 24 hours of device numeric data types represented as a line chart
- Device Data History – Contains the device’s previous data.
Device Data
This section contains two tabs – Data and Settings.
The Data tab’s first column contains the data type, the second – the value, and the last contains the sent date.

The second tab contains device settings. Here, you can change any preferences or delete the device.

Device Data Chart
The section displays mean data for several points in time for the last 24 hours grouped by location and type. By clicking on legend labels you can show and hide some lines from the chart.

Device Data History
The last section contains historical data and the option to export information in CSV format. In the picture below you can see the section.

The first part contains a filter by date. The export button generates a CSV file with data for a specific period. When you click on export, you will see a modal box that will allow you to enter the exported file’s name. The file will be available for several days in the reports section.

The second part of the section contains data type, value, date of the data, location and index. The last button with the 3 dots shows more detailed information about specific data.

In the details, you can see additional information about data including data from a table. In the picture above you can see that the location and index were not sent, MQTT topic, which receives data and the expiration date – when the data will be deleted.
