Like I said, as far as I know, there is no way to dynamically change a parameter. You can still use the 1.x binding if that was possible for that version.
I suspect that might be something that will get implement in the future if it used to be possible. But typically, on every device I’ve seen, parameters are intended to be pretty static. If they weren’t, they would be exposed using a command class in which case the parameter would show up as a Channel.
