Hi, I got in contact with Marstek and they said its possible to get the Marstek working with homey trough their API. They send me their steps but i don’t understand anything or what to do. Can someone help me with this or can someone create an app to get this working? Here you can find the 2 files…

Hi Arko,

There’s an app, not sure if this suits your needs
