I try to control my Samsung TV but with not much luck ! If it’s on I can control volume but I have no control over power on (never works) and most of time not also on power off. It’s a 2013 model upgraded 2014 (firmware up to date): UE55ES8000).
I have declared it this way:
platform: samsungtv
host: 192.168.1.10
name: TV
mac: F4:7B:5E:B5:28:BB
I have seen nothing on HA website about that control but isn’t there something specific to do to prevent TV to switch off network while in standby ?? I have deactivated already energy saver and all these stuffs but not much more luck
I’m pretty sure that is operating as designed for the Samsung TVs, at least from that generation. I have a similar model and it is the same thing. I can control it when powered on, but when it powers down the network is disabled as well.
