As I said before, fix the example. You don't need 'ports' nor a unit 
address as there is only 1 port.

All you need instead of 'ports' is 'port: true' because 
panel-common.yaml defines it.

And 'port' should be required.

You are defining a property called 'additionalProperties'. Remove the 
indentation.
