### 2/5 — Temperature

*2026-06-21, version 21.0*

No temps displayed

### 1/5 — Too expensive to purchase

*2026-06-05, version 21.0*

Surely you understand that we are all trying to save money. Charging a premium for the app is counterintuitive

### 1/5 — Expensive!

*2026-04-04, version 21.0*

What is it with the annual charge? I don’t have a contract with the weather. A modest one off fee and people would pay it.

### 1/5 — Not accurate

*2025-06-04, version 20.0*

Wasted money, miles off the reality of the output and weather forecasts. Nice interface, but defo not worth £4.00 GBP. Let alone £40.

### 2/5 — Geometrie stimmt leider nicht

*2025-04-29, version 20.0*

Die App soll den Gesamtertrag von bis zu 4 Teilanlagen mit unterschiedlichen Ausrichtungen berechnen, das ist zunächst vielversprechend. Aber wie kann es sein, dass an einem wolkenlosen Tag mit Sonnenuntergang um 20:40 die Prognose um 15:00 einbricht und um 16:00 auf null ist, trotz Ausrichtung eines Teils der Anlage nach Südwesten? Das kann nicht sein, andere Apps weisen Ertrag bis nach 20:00 aus. Das kann nur auf ein fehlerhaftes geometrisches Modell schließen. Schade.

### 1/5 — Only gives current day forecast

*2025-04-13, version 20.0*

Only gives current day forecast unless you pay and  loaded with ads. Worthless

### 1/5 — Freie Version ist sehr begrenzt

*2024-11-18, version 20.0*

Nur 1 Tag. Nur 1 Feld.

### 2/5 — Naja….

*2024-10-26, version 20.0*

Die Prognosen und die Realität sind sehr weit entfernt.

### 3/5 — Puzzling

*2024-09-15, version 19.0*

This App isn’t as intuitive as I’d hoped. Dealing with two arrays on different orientated roof pitches wasn’t simple to configure - only one can be viewed at a time.
I’d like to be able to display the combined generation forecast and see that on a single screen as both strings are connected through a common inverter. The displayed data is not clear to me yet; how i can utilise it in the best way in terms of making decisions about whether to force charge/discharge batteries or not. Early days, but not the easiest to understand by a reasonably informed householder to enable useful decision-making.

### 2/5 — Nicht genau

*2023-10-24, version 15.0*

Ich weiß nicht, von welchen Servern sich die App die lokalen Wetterdaten zieht, aber sie decken sich nicht mit den einschlägigen Wetter-Apps, so dass die Vorhersagen oft nur gewürfelt erscheinen. Die Ertragsprognosen sind, trotz korrekter Eintragung der PV Daten leider.grnauso gewürfelt.
