Can't send varying data to 1-wire memory.

Michal (and Stuart),

After Sync, I now get ${param} as ASCII in page.3 (247B706172616D7D). This occurs BEFORE I "push" the button.

Also, I can put 0 in the polling interval, but still can't leave it blank and submit.

I see in the sentence:
   "This rule makes use of the ${param} variable that is deployable in some device protocols."
Is it the case that ${param} is not "deployable" in the 1-wire device protocol implementation?
