### 5/5 — Communiquer avec son déshumidificateur

*2025-11-09*

Je trouve très pratique de pouvoir régler mon déshumidificateur aussi bien avec la télécommande et avec la Wifi et l’aide d’Alexa d’Amazon.

### 5/5 — La perfection

*2025-07-31*

Super pratique la gestion wifi ! Super application ! Simple et rapide !!

### 4/5 — iPad Mini en mode portrait

*2025-07-29*

L’application ne prend pas en compte l’iPad mini (6eme génération) de façon cohérente. 
Le Dashboard des devices est en mode paysage (ce qui est bien), et lorsque l’on choisi un device (DryFy smart) le panneau de commande de celui ci s’affiche en mode portrait. Donc, on n’utilise pas l’écran de l’iPad et le panneau de commandes est illisible (la plupart des caractères sont trop petits pour être lisibles et d’autres sont trop grands par rapport à l’interligne).
Il faut scroller vers le haut pour accéder à la totalité du panneau de commandes.

Par contre, sur IPhone c’est OK.

### 5/5 — Genial - funktioniert sofort und auch mit KI

*2025-07-05*

Ich schreibe selten Rezensionen, aber ich bin von dieser App auf Anhieb begeistert. Leichte Einrichtung, auch mit Alexa, so sollten alle Apps funktionieren! Besonders das Szenario-Feature gefällt mir, etwas, was für uns genau das ist, was wir immer gesucht haben!
Ein großes Lob an das Entwicklungsteam!

### 1/5 — Current App Version Useless

*2025-05-21, version 6.2.4*

We have a Wonderwall heater.  The previous app worked ok. The current one is useless. You have no control, it ignores schedules and settings. Switches on randomly at high temperatures I don’t need and burns through electricity as a result.  It’s been terrible for over a year.

### 4/5 — Eigentlich gut,……

*2025-05-10*

…..aber ein Dark Mode fehlt mir noch. Die Darstellung am iPad ist nur im Querformat möglich, am iPhone jedoch nur im Hochformat, bitte fixen.
Ansonsten ist die Inbetriebnahme eines neuen Gerätes, ich habe mir den DryFy Connect gegönnt, dank der sehr guten Anleitung überhaupt kein Problem. Genauso problemlos möglich ist das erstellen, bzw. einrichten einer Szene oder Automation.

### 5/5 — Super Zufrieden

*2025-02-20*

Also hier mal ein dickes Lob und eine 1 . Alles klar bei Klarstein . Wir nutzen unsere Infarotheizungen nun schon über 3 Jahre und ohne Probleme. Sehr praktisch ist die Einbindung in das Heimnetz und die Nutzung von überall auf der Welt . SUPER 🤩

### 5/5 — Très bon appareil

*2025-02-07*

Très pratique et particulièrement efficace. Cet appareil est au troisième étage et le contrôle de l’hygrométrie par smartphone est un plus. En mode automatique, il gère le taux d’humidité à souhait. Satisfait de cet achat.

### 5/5 — Great app

*2025-01-18, version 6.0.5*

Great app easy to use love the heaters too. Just getting used to them.

### 3/5 — Update

*2025-01-07, version 6.0.5*

Any chance to correct this app as temp are not reflecting real ones
