It's also possible to hack an RF remote into contact closure control if you get stuck with a skylight that's RF only. I had one job where 3 of the 14 skylights were converted to a different brand during construction because of size/fitment issues and I had to come up with a solution for HomeWorks integration with the RF remote.
Ended up pulling the remote apart and found an appropriate power source to replace the battery, then removed the switches and soldered on leads to connect to contact closures and stuck it all into a little box in the attic.
These have been working almost 3 years without issue...
