Kajetan,

I used the Python API for a power quality measurement project last summer, just to setup the meter, turn on streaming and log the mains (AC) voltage to a database.

The rest of the project was done as a web app. I used smoothiecharts to plot the voltage in realtime, and highcharts for the histograms.

I ran into a similar issue where the Python API didn’t do what I needed, but I was able to implement the missing features using the Android app source code as a reference.

Cheers, Matt
