I’ve tried to write an app and got very far, but i’m struggling a little to setup the device(s).
For now I’ve stopped the developing and fiddle a little around in HomeyScript.
With this I was (fairly ease) able to setup communcation with my PowerStream (via the EcoFLow api) directly in Homey.
With the help of some AI it cost me (only) 3 evenings 
With the help of the Virtual Device app I’m showing the values in a device.
Here is how it looks like :
I’ll restart to develop the app, but due to the fact that (for now) i’m satisfied with this It’s not a high prio thing for me anymore.
