### 4/5 — Е релакс

*2026-08-10*

Хотелось бы больше возможностей

### 2/5 — Unreliable App

*2026-04-19, version 2.4.2*

Too many incidents of Gateway Unreachable. Feedback typically stating that wifi may have changed when nothing has been changed. It is not reliable for remote control. Rather dissapointing

### 5/5 — Heating

*2026-03-29, version 2.4.2*

Works

### 1/5 — Stoped working

*2026-03-13, version 2.4.2*

Stopped working, did a reset and disabled as suggested, now will not link to Alex account

### 5/5 — Simple and effective.

*2026-03-02, version 2.4.2*

Vaillant’s remote control app for the gas boiler central heating is simple to use and effective for a boost to the regular settings if there is a cold snap. Ability to set the duration of any overrides means it’s cost effective too.

### 5/5 — 1 Thanet Road

*2026-02-22, version 2.4.2*

Ok

### 2/5 — Unreliable

*2026-02-22, version 2.4.2*

Constantly looses connection during the day (and every day), so having to keep checking and set temperature manually on thermostat. Use to be much better?

### 1/5 — Müll App

*2026-02-10*

Nicht mal die Brauchwasser Temperatur lässt sich regulieren, Druck zeigt es auch nicht an.

**Developer response:** Hallo vinc444,

vielen Dank für Ihre Bewertung. Wir bedauern, dass Sie nicht alle Daten einsehen können. Wir nehmen Ihr Feedback selbstverständlich mit und arbeiten weiter an der Verbesserung unserer App.

Viele Grüße
Ihr Vaillant Team

### 1/5 — Nicht erreichbar

*2026-01-25*

Es funktioniert einfach nicht. Ich kann nicht dreimal am Tag den Router vom Strom nehmen, dass ich meine Heizung steuern kann für die anderen Geräte ist das nicht gut. Nur weil Vaillant das nicht auf die Reihe bekommt. Es ist einfach nur schlecht rausgeschmissenes Geld nicht zu empfehlen. Ich habe sowas ähnliches von Junkers. Seit zehn Jahren läuft es ohne Probleme.
Es ist einfach nur ein billiger China Import!!

Andauernd ist der Getaway nicht erreichbar. Es geht mal zwei Tage gut und dann ist wieder alles dahin und man muss fünf mal am Tag wieder alles neu einstellen. Trotz einem WLAN Verstärker, der in 40 cm Entfernung von dem Getaway ist. 
So hat das Gerät wirklich keinen Sinn

**Developer response:** Hallo mik1705,

vielen Dank für Ihr Feedback. Wir bedauern, dass es bei der Nutzung der eRELAX App zu den beschriebenen Problemen kommt. Am besten wenden Sie sich diesbezüglich nochmal direkt an unseren App Support (app-support@vaillant-group.com).

Viele Grüße,
Ihr Vaillant Team
