I just released another alpha version. This version fixes a long lasting and irritating bug. This bug caused that some days would be reported as 0 or an insane amount of kWh while the other charts were reporting the production correctly.
Problem was that this was an intermittent bug and very hard to reproduce. But I do think I have nailed the problem once and for all.
Even though this is labeled as an ALPHA version I have been using this version for a few months now and have not found any new introduced bugs.
This version still uses the 1.6 template system. When the 2.0 version is finished you will ( finally ) have a completely new frontend.
