adminandClaude Opus 5 79843aa2ae SolarManager unter Versionsverwaltung
Erster Stand der Hintergrundprozesse, die auf der Synology unter
/volume1/homes/wagner/SolarManager laufen: der Manager selbst, die Sammler
je Geraet, die MQTT-Bruecke, der Wecker und - neu hinzugezogen - der
AutoAction-Runner, der als Hintergrundprozess hierher gehoert und nicht ins
Web-Verzeichnis.

Zugangsdaten stehen nicht mehr im Quelltext, sondern in config.ini, die
nicht mit eingecheckt wird. Vorlage ist config.ini.example, gelesen wird sie
von konfig.py. Betroffen waren solarManager.py (Datenbank und Wattpilot),
zeit.py, gatherWaterData.py, wecker.py und skoda_testdaten.py, das sich das
Passwort bisher aus dem Quelltext eines anderen Moduls herausgesucht hat.

Die Kia-Anbindung ist mit dem Fahrzeug entfallen: kiaTest.py,
gatherCarData.py und hyundai_kia_connect_api sind nicht mehr dabei, ebenso
gatherInverterData.py, auf das nur noch eine auskommentierte Zeile zeigte.

Die mitgelieferten Bibliotheken bleiben im Repository - die NAS hat kein
pip, sie muessen neben den Skripten liegen.

# Low level CRC functions for use by crcmod. This version is implemented in
# Python for a couple of reasons. 1) Provide a reference implememtation.
# 2) Provide a version that can be used on systems where a C compiler is not
# available for building extension modules.
