I’ve just started testing your platform for a project in my company. Initially, we are simply updating 2 datastreams (temperature and waterflow). The temperature is displayed in a gauge widget in the web dashboard and updates correctly and quickly. The temperature is in a chart, and it updates with significant delay. Browser refresh does not seem to help.
If I switch to the “Latest” view it does not necessarily match the latest value in the “Last hour” graph. Sometimes it will even say “No data”. I am aware that the granularity is 1 minute, so at the moment I update the datastream less frequently.
When writing to the datastream I use the command:
The result variable is type uint16_t.
On a final note, I do not see the “SUM” option when configuring the chart, although it is mentioned in the help text. I only see AVG, MIN and MAX.
I hope you can help.
