I've been learning more and more about home automation and have opted to use z-wave devices for most of my system. With the addition of the SQ Blaster and SQ Remote iPad app I've been able to make a wonderful remote control system for my home.
The garage door opener became a bit more of an urgent issue recently when a neighbor called and told me that my garage door had been left open all day. With this project in combination with a door/window sensor I'll be able to keep myself apprised of such oversights in the future and be able to take care of it from anywhere in the world!
Giving credit where credit's due:
Please note that this concept was not my original idea. I Googled "z-wave garage door opener" and came across a video of someone else's very similar concoction. My only contribution is making this instructalbe and using my electromechanical experience to streamline the final device.
I accept no responsibility for any damages to persons or property caused by following this Instructable. Please use caution any time you handle soldering irons, interact with high voltages and climb ladders! ;-)
Z-wave plug-in appliance switch (I used an Intermatic HA02C, $27 on eBay)
120v relay (I used Radio Shack model #275-217, $9)
Project Enclosure (I used Radio Shack model 270-1801, $3)
Power cord (Mine was cut off a dead fan)
Approx. 3' of 2-conductor wire (any small guage, 20-26AWG, will do)
Double-sided foam tape
Z-wave door/window sensor to indicate DOOR CLOSED state (not shown in this instructable).
I've purchased a few "Aeon Labs Z-Wave Magnetic Door / Window Sensors" from eBay (not yet received).
As most garage doors are metallic and I've read that the metals often interfere with the reliability of the magnetic properties of the sensor, I'll be mounting my sensor and it's triggering magnet to plexiglas brackets mounted to the door and rails to lift it away from the ferrous metals. I just wanted to pass on this tip to save you some troubleshooting time in case you come across this problem in your own implementation.
