Are there any specified application ID's that are guaranteed never to be used by Clipsal? Reading the C-Bus Applications document it states that the range </body> to </body>F are available for free use, but then goes on to say However their use is discouraged. I don't want to actually send messages onto the bus with this ID, but I do want to make sure I will never receive messages with this particular ID, because I want to use it internally in my software for another purpose. So is there an ID that can be used? Cheers Rohan
