Following up in this issue, I tried the example, but the query is only returning one value (the latest), and not a stream es expected after using the opcions:
I have a similar problem - My data stream only ever shows 1 data point whereas I was expecting see at least 8 data points when capturing data using Massa M3 sensor & digi ConnectPort X4 gateway.
Someone please help!
Check the Data Streams under Data Services. If you can see the data stream history then when you request the Data Stream you will get the history, else there is some issue with your account i think.
