Diese Seite beschreibt die Verwendung eines Digitalen Bilderrahmens (DPF) als Display für FHEM. Die Anbindung erfolgt dabei an einen separaten Raspberry Pi, auf welchem lcd4linux läuft. Dies ermöglicht die Verwendung einer Vielzahl von verschiedenen preiswerten Displays, die keine großartigen Fähigkeiten aufweisen müssen.
Auf der Seite Digitaler Bilderrahmen wird ein Ansatz beschrieben, der mit komplexeren DPF arbeitet.
Voraussetzungen
- Digitaler Bilderrahmen, der über lcd4linux ansteuerbar ist, z.B. Samsung SPF85H.
- Raspberry Pi mit LAN oder WLAN Interface.
Achtung: Prinzipiell ließe sich das lcd4linux auch auf FHEM-Rechner installieren - allerdings sind Performance-Probleme auf den hier verwendeten Kleinstrechnern nicht ausgeschlossen.
Installation
Auf dem Raspberry Pi sind die Anwendungen socat, ImageMagick und lcd4linux zu installieren. lcd4linux sollte beim Hochfahren des Raspberry Pi automatisch starten.
Werte holen von FHEM
Zunächst wird (z.B. im Verzeichnis /opt/fhem) eine Skriptdatei getFHEM.sh angelegt.

Erzeugung einer Fotodatei
Erzeugung eines PNG-Files aus einer aus einem Ordner zufällig ausgewählten anderen Datei. Dazu wird im Verzeichnis /opt/fhem die Datei createPic.sh angelegt:

Erzeugen von Balkendiagrammen
Balkendiagramme werden erzeugt, indem die von FHEM übermittelten Werte mittels eines weiteren Skripts als Eingabeparameter für das Programm convert aus der ImageMagick-Suite benutzt werden. Drei verschiedene Farbschemata für diese Diagramme - genannt green, red und blue -- sind hier vordefiniert
Hierzu wird (z.B. im Verzeichnis /opt/fhem) eine Skriptdatei createBar.sh angelegt:
