I'm getting

I've got this as my config
src = 'IP of PC' # ip of remote
mac = 'Mac of PC' # mac of remote
remote = 'Hostname of PC' # remote name
dst = 'IP of TV' # ip of tv
app = 'python' # iphone..iapp.samsung
tv = '[TV] Samsung' # Name of my TV

and set the port to 8001 as i've got a 2015 tv

I don't actually have a SmartThings HUB, I've been trying to control my TV via my pc or Hassio

Do you know the way we can send the mouse pointer movement command to Samsung 2013 TV ?
