Since I have 2 dumb reed sensors (on ea. for full-open / full-closed door position) attached to my Z17, my setup was rather unorthodox -- my hodgepodge dashboard setup was pretty darn ugly lol (but worked fine overall).
I don't know why it took me so long to try it, but I just recently installed Kevin's GDO app as detailed here (starting Step 3) -- man, it totally works like a champ - I love it!!
Kevin's app enables you to set a 2-sec (IIRC) auto-off for the relay so that it mimics the wall switch's momentary button behavior. Or you can use the Basic Z-wave Tool to tweak that parameter -- I went that route a while ago before I tried Kevin's app. Either way to set auto-off for the relay will work perfectly fine.
Good luck with your install!!
