 **amp (Optional)** | Boolean, defaults to False. Set this to True if you have an amplifier attached to the TV and not use the internal TV speakers. Then the volume slider will not be shown as this doesn’t work for the amplifier. Mute and volume up and down buttons are there and working with an amplifier.
 **android (Optional)** | Boolean, defaults to False. Set this to True when you have an Android TV as these TV’s don’t respond to WakeOn LAN commands, so another method of turning on the TV can be used.
-**sourcefilter (Optional)** | List of text that is used to filter the source list, eg. ’ HD’ (with quotes) will only show TV channels in the source list which contain ‘HD’, eg. ‘NPO 3 HD’ (in my config this will only show HD channels)
