API - Get historic data including percent used for all channels of sensor "WMI Free Disk Space"




I'm a bit stuck constructing a specific api call and need some help.

I need at least the following data: Percent used/free, Bytes used or free, for all channels of a "WMI Free Disk Space" sensor for a specific date. The following html report contains the data I need:


Using the api I've created the following query:


This returns free bytes for all channels, but no percentage used/free.

datetime        : 01.01.2023 00:00:48
Summe           : 52349521920.0000
Freie Bytes C:  : 21604192256.0000
Freier Platz C: : 34.0000
Freie Bytes D:  : 30745329664.0000
Freier Platz D: : 19.0000
coverage        : 100 %


Adjusting the api call to match parameters from the html report:


returns only the percentage for one channel, without free bytes:

datetime     : 01.01.2023 00:00:42
datetime_raw : 44926.9588202778
value        : 2 %
value_raw    : 2.0000
coverage     : 100 %
coverage_raw : 10000

How do I construct an api call to get all channels of a sensor, including free bytes and % used?

Thanks in advance

Hello, we would like to see how a regular report shows the information and compare it with the API report as well as some screenshots of your sensors. Therefore please send us all this information on a ticket at [email protected] so we can work better there.
