### 5/5 — Funktioniert

*2025-04-25, version 1.8.2*

Die App macht was sie soll.

### 2/5 — Sehr sehr Luft nach oben

*2023-04-01, version 1.7.2*

Man kann leider nicht die Kamera der Sprechanlage anmachen oder die Tür aufmachen, wenn es geklingelt hat, ohne den „Sprechen“ Knopf zu drücken. Somit bekommt derjenige vor der Tür immer mit, ob man zu Hause ist oder nicht. Nur mal gucken geht nicht. Sobald man sich über das Handy auf die Klinkelanlage aufgewählt hat, kann sich kein anderer mehr aufwählen, Kamera einschalten oder die Tür aufdrücken. Auch nicht über die stationäre Sprechanlage. Zusammenfassung: gut gedacht, aber sehr viel Luft nach oben. Sprechanlage: Villa AP
und iLifestyle Cloud

### 1/5 — Stürzt ab

*2022-11-18, version 1.7.2*

Kann meine Geräte nicht einpflegen, weil die Apps ständig abstürzt. Der Support ist auch nicht erreichbar. Sehr sehr schade. Wollte die App als Ergänzung zu unserem Villa Tür öffner nutzen. Funktioniert leider nicht. Würde mich über Antwort des Supports freuen, damit Dad Problem schnell behoben werden kann.
