Good evening.

Last year, I created an app for the Marstek Venus E and have now made it compatible with the AlphaESS. Would any of you be interested in testing it with me?

This is my app: [Smart Charging for Home Battery | Homey](https://homey.app/nl-nl/app/com.energyprices.app/SlimLaden-voor-ThuisBatterij/)

It is a very comprehensive app with a lively forum. I would really appreciate your help.

Is your app compatible with the Alpha ESS Smile G3 S5\*\*?\*\* If so, I would like to help as soon it’s installed, probably within in a few weeks.

Ja dat klopt. Wordt ondersteund. Ik heb hem al getest met een gebruiker. Maar is niet verkeerd om nog eens goed samen te kijken.

When installimg it shows a warning that this app can comtrol tour entire homey. Can you make a version with more restrict access?

This happens because the app needs data from other devices on your homey, like p1 meter. So not possible to make restrictions. The app will be without use.

Best you come to our forum from the app. There are Alphaess-users working with my app. [[APP][Pro] SlimLaden voor Thuisbatterij - Marstek, Sessy, Homewizard, IndeVolt, Victron, AlphaESS en Nexus(Zonneplan)](https://community.homey.app/t/app-pro-slimladen-voor-thuisbatterij-marstek-sessy-homewizard-indevolt-victron-alphaess-en-nexus-zonneplan/140156)
