@balmli I have a “very” old Samsung TV from 2011. It is an UE46D6500 and it seems not working with your app at the moment. It does not respond to Port 55000 and 8001.
But there is a working api for iobroker that supports TV´s older than 2014 and this works fine in my case.
So maybe you are interested to implement this, to support also TV´s before 2014.
For sure I would help testing
