Hi,

in general the realtime updates are working fine with multiple datapoints:

You see these gaps when there is no data for a specific data point at the given timestamp.
In the above screenshot you can see these gaps as the Temperature Simulator is sending measurements in a different rhythm compared to the acceleration measurements.

If your measurements are all sent with same timestamp, please provide the data structure of your measurements (measurement API) so we can have a closer look.

Regards,
Tristan

Hi Tristan,
Sample data are exported from Cumulocity trial tenant.
I think these 3 measurements should with same timestamp.

Sorry, but the CSV export does not help us to look into this… Please provide the JSON returned by Cumulocity IoT - OpenAPI Specification for these measurements.

This might relate to the internal ticket MTM-54107 we are currently working on.

Hi Tristan,
The json from measurement OpenAPI.
Thanks for your support again.

From the shared txt it’s pretty obvious you are not following best practices:

Even the measurement share the same timestamp you always create one measurement document for each value which is kind of bad design and also leads to the thing that you have observed, that in a data point table always only one value is displayed because the document only has one value… even they have the same timestamp.
