-# Aruba PoE
+# PoE Manager Web-App
 
-```
-Dieses Repo konfiguriert auf Ubuntu/Debian einen Service,
-dieser Service ist in der Lage IPs zu Pingen und entsprechend daran POE auf vorgegebenen Ports an einem Aruba Switch
-zu Aktivieren bzw. Deaktivieren.
-```
+Webbasierte Verwaltung und Monitoring von PoE-Devices und Switches.  
+Die App ermöglicht:
 
-Download:
+- Anzeige von Device-Status (Online/Offline)
+- Verwaltung von Devices und Switches
+- Einstellung des Prüfintervalls
+- Live-Log-Ansicht
+- Benutzerverwaltung mit Adminrechten
+
+---
+
