Sweet!
If you don't mind sharing....
What specific physical devices did you use?
and then I hook them up to a z-wave contact switch:
Which SmartApp are you using, or is yours controlled by the thermostat?
I just wrote a simple app that said if the temperature in the zone 2 was more than 3 degrees off from the themostat (in zone 1), close the damper on zone 1
How many 'zones' do you have now?
Just 2
How long have you had it all set up, and how is it working out so far?
I originally set this up on Vera in 2011 or so, but then moved it over to SmartThings in 2013
