I am trying to create a card that lets me switch the source of the amplifier in my kitchen. The amplifier is an OSD Nero Stream, which runs on the linkplay hardware, and is added to HA via the Linkplay Integration. I can change the source by inspecting the device seen here https://i.imgur.com/uSmwFiu.png
but i need a selector on my dashboard and cant figure it out, and more importantly need to be able to change it with automations
