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.

<h3>VBUSIF</h3>
<ul>
This module connects to the RESOL VBUS LAN or Serial Port adapter.
It serves as the "physical" counterpart to the <a href="#VBUSDevice">VBUSDevice</a>
devices.
<br /><br />
<a name="VBUSIF_Define"></a>
<b>Define</b>
<ul>
<code>define <name> VBUS <device></code>
<br />
<br />
<device> is a <host>:<port> combination, where
<host> is the address of the RESOL LAN Adapter and <port> 7053.
<br />
Examples:
<ul>
<code>define vbus VBUSIF 192.168.1.69:7053</code>

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
