It would be nice if the standard switch node shows the payload of the property. The switch node from node-red-contrib-ccu : ccu-switch shows the payload and the output number from the switch node. Here is an example of it.
In the first node I read the control status. It is true, so the first output is active.
In the second node the state of the sun is read. It is false, so the second output is active.
It would be nice if the standard switch node do it in the same way.
