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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

A subclass that replaces the write method with one that toggles RTS

|
according to the RS485 settings.
|
|
|
|
NOTE: This may work unreliably on some serial ports (control signals not
|
|
synchronized or delayed compared to data). Using delays may be
|
|
unreliable (varying times, larger than expected) as the OS may not
|
|
support very fine grained delays (no smaller than in the order of
|
|
tens of milliseconds).
|
|
|
|
NOTE: Some implementations support this natively. Better performance
|
|
can be expected when the native version is used.
|

|
|
NOTE: The loopback property is ignored by this implementation. The actual
|
|
behavior depends on the used hardware.
