ich versuche mit einem Raspberry Pi, einem PIR-Sensor und einer Webcam eine Raumüberwachung zu realisieren.
Die Aufnahme wird auf eine extrene SD Karte gespeichert und per eMail an mein eMail-Account gesendet.
Das Script macht was es soll, hat aber ein Problem.
Die erste Mail hat ein Bild im Anhang, die zweite Mail 2 Bilder im Anhang usw.
Hat jemand von euch eine Idee wo der Fehleer liegt?!
Gruß und Dank
Joachim
