, ich in recht neu in der Sprache und habe ein Kleine Projekt für meine Büropflanzen rausgesucht, um diese zu bewässern.
Leider erhalte ich derzeit folgende Fehlermeldung:
---------------------------------------------------------------------------------------------------------------------------------------

Ich hoffe mir kann da einer weiterhelfen
Vielen Dank
