Kurzbeschreibung
Das Vbus-Modul verbindet einen Vbus-Lan adapter mit FHEM.
Voraussetzung
Voraussetzung zur Anbindung eines VBus Device an FHEM ist das eine Netzwerkverbindung besteht die zur Verfügung stehenden Module:
19_VBUSIF.pm 21_VBUSDEV.pm
genutzt werden. Diese Dateien müssen in den Ordner /opt/fhem/FHEM kopiert werden und es findet keine aktualisierung beim Update statt.

Installation RESOL VBUS LAN Gateway
- Erstmal keine Einstellungen am VBUS/Lan Gateway (Passwort/Port etc) vornehmen
- Die Ip_adresse herausfinden (z.B. am Router) und prüfen ob man per Browser darauf zugreifen kann
- Optional: Testen ob Daten ankommen mit der service center Software von Resol
- Dann nur das VBUSIF als define eintragen
Definition
define <name> VBUSIF <IP des VBus-Lan> <Port muss 7053 bleiben>
define vbus VBUSIF 192.168.1.25:7053 attr vbus event-min-interval .*:120 attr vbus verbose 5
