Edimax Kamera mit MQTT steuern über ein Dashboard

Vor kurzen hab ich die Edimax Kamera IC-7112W gekauft  mit Pan/Tilt Funktion. Dh. die Kamera ist drehbar um 355 Grad und 120 Grad nach oben.

Die Kamera gibt es hier bei Amazon : http://amzn.to/2jY3DIn

Nun wäre es geschickt die Kamera per Fernsteuerbefehle mit MQTT zu steuern, damit sich die Kamera in die gewünschte Richtung dreht. Dazu habe ich einen Raspberry Pi mit Node-Red genutzt und einen einfach Flow programmiert. Als Webinterface benutze ich „node-red-dashboard“ welches auf der laufenden Node-Red Instanz installiert sein muss.

Hier der Code:

Die Steuerbefehle für MQTT sind „Home“, „left“ und „right“ und zwar genau exakt in dieser Schreibweise. Die Steuerung kann mit dem Programm „MQTT Dashboard“ durchgeführt werden, welches es kostenlos für Android gibt unter : MQTT Dashboard
