Hi there,
as mentioned somewhere before it’s not possible yet, but direct coupling is a point on my roadmap. It’s a very special Homematic-thing, so it wasn’t that hight prority so far.
@arkimede the Admin UI is based on symfony. You could have a look at Controller/Admin/Inventory/DeviceController.php and Model/Admin/HomegearDevice.php. I’m using plain VSCode, and a virtual machine with a homgear nightly installed
