user variables on floorplan/roomplan ?

[willemd]

Can I add user variables and their values to a roomplan or floorplan? Or can I only display devices there ?

I want to use a roomplan to display a flowchart of my energy costs calculation. Some elements of the calculation sit in devices (like electricity usage or return), other elements I have stored in user variables, such as transport costs and tax costs.

I could use devices to hold the values of these cost elements, but would prefer to stick to user variables for this purpose.
