    I was interested in using this app for display of my information from Unfortunately I can find no help other than a German language website. Still not sure if it is even possible. No choice but to uninstall.

    Doesn't have the same amount of features and supported devices as SolarAnalyzer, but it does a very good job with what it supports. The full featured version of SolarAnalyzer isn't exactly cheap, so for most people this may be the way to go.
