The main problems at the moment is there is a bit of user confusion when trying to setup the ROS TV card.
You really need to separate the Apple TV and Android TV into separate cards especially as you have different mappings for each. This way they can auto setup for the device.
Then you need a Harmony Hub TV card that enables
- The user to choose separate ON/OFF buttons. (this may be a power behaviour option in the current card, like what Apple TV gives)
- Map the select.harmony_activities to the source selection.
- Be aware of which Harmony Activity is active and map different commands to the buttons per activity.
- Enable the coloured buttons to be mapped as well as all other hardware buttons (currently not possible in the current TV Card).
- Enabling button.* entities to be mapped is also required.
Emulating the Firemote model will get you a long way there.
