Episode 4: The Last Alpha

After many bugfixes I have the impression the program now does not crash any more, so this will be the last alpha-Version.

The remaining bugs more or less focus on the WebUi which does not entierely work yet.

Before opening an issue check if there already is a FIXIT: TODO: or even BUG: documented in the code.

Current known bugs and todos:

Some of the big bugs might not be bugs any more - I left them open to recheck! So the state of the code likely is better than documented here!
Bugs and Fixmes have a dot before the line!

Episode 3: The bugs strike bag

I have corrected many bugs and for me personally I will put the program now into regular test mode.
The home battery optimization is not tested yet as my home battery has been disconnected by the electiricians as I get more PV on my rooftop installed. From next week I will be able to test.

Episode 2: The Alpha Menace

SmartCharge v0.0.2-alpha Release

❗ A warning

I had my pv system extended. As there were parts missing the electricians could not finish their work with the result that my power inverters for pv and battery do not work any more. So my battery charging logic has not been tested thoroughly.

Things added

• I added a webserver to safely edit the settings and the trips
• updated the readme with better installation instructions
• refined the logic that it includes a "battery guard" which requests the home battery soc in shorter intervals to stop charging the home battery as this function is not implemented in evcc
• bugfixes

Limitations

clockpicker / datepicker are buggy - you can enter times manually. You are welcome to fix and open a pull request.
And of course this is alpha stage - there are more unwanted christmas presents in the software for sure!
