Übersichtliche App mit ein paar Schwächen

Die App ist übersichtlich gestaltet und zeigt die meisten Infos vom WR an. Auch gibt es die Möglichkeit in die WR Verwaltung zu wechseln. Leider ist es mir ein Rätsel wie man aus der App den Wechselrichter aktualisiert (Firmware) es wir angezeigt dass es ein Update gibt aber man kann es nicht imitieren. Außerdem stört in der Erzeugungsübersicht, dass die Umrechnung in km und l Warmwasser nicht aus dem Einspeisewert berechnet wird. Die umschließende Box suggeriert dies, es wird jedoch der Gesamterzeugungswert für die Berechnung herangezogen. Das ist leider irreführend.
Weiterhin ist es schade dass die Leistung nicht pro String erfasst wird.

Doesn’t work

I’ve been getting black out emails from fronius and no solar read out. This app has been useless as it doesn’t work- it just gets stuck on the terms and conditions despite numerous times to download, Agree or accept them. A bit over this.
