### 3/5 — Schade, funktioniert

*2025-04-01, version 1.2.0*

Nicht mehr mit onBattery Version, aber ganz nett

### 3/5 — Verbindet nicht

*2025-01-19, version 1.1.0*

Keine Verbindung zur Fritz!box  und   OpenDTU möglich. URL wird nicht erkannt . Fehler 1022 . Browserinterface funktioniert.

### 3/5 — Kein HTTPS Zugang

*2024-09-29, version 1.1.0*

Leider ist keine https Verbindung möglich wenn man in der Fritz.Box eine Freihabe auf u.b. Port 88 setzt. Es kommt immer der Fehler : Error 1022 ( An SSL error … ). Weder die Eingabe mit https noch http funktioniert. Opendtu via Web Browser funktioniert einwandfrei

### 2/5 — Hängt immer wieder

*2024-06-23, version 1.1.0*

Egal, was du ändern willst oder sehen willst, kommt fetching Data und nichts weiter.

### 4/5 — Good and clear app

*2024-03-04, version 1.0.3*

It would be nice if you could also insert a web address instead of just an IP. My OpenDTU can be reached via a DNS server.
