Review of updates

The app was recently updated (Fall 2026) to a less functional dashboard. The graphic information we always looked at is now buried in the app and you have to search for it instead of it being easy to find. They got rid of the option to choose a dark background and everything is much harder to read on the bright white background, it gives me a headache. I wish I could undo the last update.

Time to add HomeKit support

Next update should add HomeKit support

Très bonne application de suivi de production électrique et de consommation avec une batterie

EMA app est une très bonne application de suivi de production électrique avec plein de tableaux de suivi (horaire, quotidien, mensuel et annuel) ainsi que la production panneau par panneau qui permet détecter quand il y a un disfonctionnement.
Avec en plus une batterie, la gestion de la consommation est des plus fines et l’on sait à tout moment d’où vient l’électricité que l’on utilise (panneaux photovoltaïques, batteries ou réseau électrique)
Fonctionne très bien sûr iPhone et iPad (juste quelques petites bugs sur l’interface graphique pour les tablettes que j’espère que les développeurs vont rapidement corriger mais rien de rédhibitoire)

Where did the individual panel info go?

The individual panel information disappeared. There is no help menu. There is no meaningful setting capability or explanation of the setting values.
This is the worst “upgrade” of an app that actually runs that I have ever had the misfortune to install.

Please fix this ASAP!!!

works but not well for a human reader

The update rearranged the ui such that you have to traverse through multiple pages to see useful information like power output per module. A step backwards from the previous ui.

A Bad App from a Bad Company

Don’t believe them when they say they’ve fixed some bugs. They never actually do. The app is still bad.

Avoid APsystems inverters if possible. Very poor tech support and a lousy app. Often misses data or shuts down while the sun is still shining. So little effort they don’t even have a dark mode icon. That would take two minutes but that’s two minutes they don’t want to spend. Even having a two star rating is too high for this company.

Upgrade is a downgrade

Do not update this app to 9.0. You will lose all relevant data and panels read NC without showing performance.

Garbage update

The new app makes it several extra taps to get the information you need. Why do we need AI trash in the app? Just give me the data.

App

New version is not good old version is better

Broken (update - sep 21/26 update fixed app)

Update - the update on sep 21/26 appears to have fixed the missing info. Rating updated to reflect that the app is now working

The new update (Sep/2026) has broken part of the app. I see real time info, but get “data receiving failed “ for any attempt at looking at the “apems” tab. Please roll back the update, it wasn’t broken and worked fine before.

The new update is awful.

Horrible update

Since the new update there is ZERO useful information! No graphs or ANYTHING other than “current power”. Revert back please!!!!

Pourquoi changer une application qui donne satisfaction ?

Alors, je sais, j’aurais dû venir avant pour écrire que l’application était simple mais efficace et permettait en un coup d’œil de voir l’historique de la consommation de la journée par rapport à la production. Mais tant pis, aujourd’hui je viens dire que je trouve la dernière mise à jour inutilement complexe et donc pourrie. On accède à des menus de graphiques en tâtonnant, les graph sont sans doute plus cohérents d’un point de vue mathématique (la consommation c’est du négatif à présent, ok c’est logique) mais c’est moins lisible. Quand vous comparez deux courbes positives, c’est beaucoup plus simple de voir celle qui dépasse l’autre, même si l’une représente la production et l’autre la conso. Bref, je suis particulièrement déçue par la nouvelle interface. Je croise les doigts pour que vous reveniez en arrière comme c’était déjà arrivé après que vous ayez intégré l’image du maison qui rendait les valeurs illisibles. Encore une grande idée d’UI/UX qui a oublié un élément essentiel : l’utilisateur final lamba…

New update wrecks app.

The single function I use this app for is individual panel production. Previously that was a single click. Now it is hidden behind several unnecessary levels.

Additionally, what possible use could AI be in this app whose only purpose is to report how much solar energy is being produced. Hop off the bandwagon and keep the app simple.

Avoid new version

If you can avoid updating to 9.0, don’t update. The 9.0 version doesn’t let me see even 1/3 of the info I used to see. The “helpful” video shows that you can revert to the classic view, but I don’t have the theme option in settings as the video shows. Horrible, horrible “update”.

Broken

Ever since last update overhaul you cannot see your monthly or yearly production or you panel view

Downgrade from the previous version

The human interface is busy and clumsy, the screen with the rotating planets is almost useless: since I have only one ECU, so there’s no reason for me to have to tap on it, and the rest of that screen doesn’t really show me much.

The monthly report shows only from January, not the preceding 12 months. This makes it hard to see the seasonal pattern, which doesn’t care about our calendar.

Quite often the data reported is stale: a few days ago it was almost 2 hours stale on the Day graph, no easy way to get reasonably current data.
Right now it’s at least five minutes out of date.

Number formatting is a mess, for total energy, instead of showing n Mwh it shows n k …

I’d like to see the old version come back.

Terrible new interface. No reports.

Awful update. Revert back to the old UI. reports are gone. Trash.

New version is horrid

It’s like they are trying to hide all your solar data from you suddenly. New daily curve is so small and hard to view. Oh and they made it super painful to even find.

Somethings wrong with v9 update

The new v9 app update has lost much of its functionality. EMA was working great until this update. Sent a request to be able to go back a version but no response yet. Hope they’ll fix it very soon. At least communicate that they’re working to fix it.

Worse update

Not showing any data , always says data received failed . make it work or downgrade back to previous version.
