, can the i-Tach be set up to give me feedback to know if the doors are open or closed?
I use a gc-100-12 with contact closure to control my garage doors. I ran a cat5 cable from my equipment rack and used 4 of the wires to wire in to my 2 garage door buttons on the wall. Works great. The global cache relay device in the builder is what I am using. I've found that sending the ON command followed by a .8 second delay and then the OFF command and then another .8 delay and the OFF command again ensures that all works well. A few times before adding that second OFF command the contact closure stuck ON, which was like holding the garage door button down, this prevented my garage door from functioning with my regular RF remote in my car. Haven't had a problem since adding it.
Feedback isn't possible. There is a query command, but I believe it will only tell you if the contact closure is ON or OFF which doesn't really tell you if your garage door is open or closed.
I use Tasker on my Android phone to launch iRule when within range of my home WiFi. When I'm walking back home from the park with my kids I just pull out my phone and there is my iRule garage door home panel, press the number 1 button and up goes the door. It's great only having to take my phone with me going places, no more keys or spare garage door opener.
I have no experience with it, but I do use other insteon devices with iRule, they have a garage door kit that would provide feedback if I it works as their other devices do. If you have other lighting and automation needs that might be something to look in to. You could also add a cheap IP camera which is something I've thought of doing and get visual confirmation that the door is open or closed.
Good luck with your project.
