Hi Leute,
ich hab mir mal die Mühe gemacht das Nagios Plugin für Shellys zu überarbeiten damit es auch mit Gen2 funktioniert.
Bitte verzeiht mir den "schrecklichen" Code. Ich bin halt kein Programmierer 
Wenn das jemand aufhübschen möchte dann gerne 
Ich denke mir halt, hauptsache es funktioniert 
Falls jemand Fehler finden sollte dann bitte hier posten. Aber vorab zur Info, ich hatte gerade Urlaub und Zeit. Ansonsten ist meine Zeit begrenzt und je nach Umfang werd ich mich nicht zeitnah mit dem Problem auseinander setzen können.
Das Skript ist in php geschrieben und gedacht für den Einsatz mit CheckMK oder Nagios.
Aber bitte keine Anfragen wie man das ganze in CheckMK oder Nagios reinbekommt. Da fehlt mir aktuell die Zeit dazu und es gibt eigentlich auch genügend Tutorials bzw. bei CheckMK ist es in der Doku erklärt.
Original stammt von https://github.com/shelly-tools/check_shelly
Viel Spaß damit
