I have an item UN65JS850D (UN65JS850D) appearing in my dashboard (seemingly from automatic discovery) but neither the power button nor the TTS buttons do anything. Is there something more that needs to be done in order to control this TV?
Will need to check what features your TV supports. I have an old Panasonic, it has a network port for the built in app’s, it appears in HA, but it doesn’t support anything in HA apart from being switched off, can’t even switch it back on, only off
