Hallo liebe Forenmitglieder,
habe bei mir mehrere Steckdosen KP105 mit den Raspberry am laufen. Das funktioniert auch soweit ganz gut.
Die Statusabfrage wird über 2 Python Scripte realisiert.

Das Problem was ich habe, ist wenn eine Steckdose nicht erreichbar ist, das die Abfrage unterbrochen wird. Das Script tplink_smartplug.py gibt zwar wenn ich die Abfrage über der Console mache die Fehlermeldung print ("Cound not connect to host " + ip + ":" + str(port)) aus.
Um auf meiner Webseite zu erkennen das eine Steckdose ausgefallen ist, benötige ich im Script Auslesen.py den Wert "99" in der Variable outputxx.
Das ist das Problem was ich im Moment habe.
Was muss ich ändern, habe schon versucht das zu realisieren. Aber leider habe ich noch zu wenig mit Python bis jetzt zu tun gehabt.
