This is just a quick little write-up on how I wired up my overhead garage door so I can control it with my phone/any pc, using Z-Wave. The controller I’m using is the 2Gig panel, bought from SafeLife Alarm. If you’re looking for an alarm system with monitoring, where you can have video cameras viewable from your phone and control your thermostat, lights, etc. – contact Debbie at SafeLife Alarm (direct line 877-826-5443) and tell her Thomas sent you.
Evolve LFM 20 Relay Z-Wave
If you want to control your overhead garage door with Z-Wave, there’s nothing out right now (as of March 2012) which lets you do it in a plug and play fashion. One company, 2Gig, does offer some device that lets you use a keyfob to open/close it – BUT that isn’t Z-Wave so it doesn’t count. What you’re going to need is an Evolve LFM 20 Relay Fixture Module, I got mine off Amazon:
There are 6 wires on it, a yellow, a white, a black, a green, and two blues:
As you can see above: White, Black and Green get connected into a power cord. Yellow is unused, just snip the end and put a cap on it.
The two blues get connected in parallel to the garage door button – what I did was connect one blue wire to the red wire/one blue wire to the white wire directly on the garage overhead door unit itself. You’re going to notice the gauge is too small (wire too big) to fit inside the screw hole, so you’ll need to use some smaller wiring. I cut wiring off a 4pin molex connector and connected it all together, as seen below:
This way the garage door button and our homelink systems in our cars still work too, as well as being able to open/close the garage door using our phones or the 2Gig panel.
Operating the Overhead Garage Door
To open and close the garage, it’s a little counter-intuitive based on the verbiage of “On” and “Off” as a light. Basically, in order to open OR close the garage, you hit “On”. That closes the loop on the garage overhead door unit, allowing it to start opening/closing the door. You have to turn it back “Off” to open the loop back up, so that it’s not stuck receiving power.
The way I’m going to resolve that issue so that the garage door is never stuck in closed loop, is get one of these (already placed the order) and set up a rule that says when the sensor opens or closes, turn the relay off (opens the loop back up):
Think of it like this, when the garage door opens, the sensor will go off saying the garage door contact is OPEN. I will set up a rule that says when that sensor reports being open, turn OFF the “light”, aka the LFM 20 relay. This opens the loop back up. Same for when the garage door closes, the sensor comes back in contact and says the door is closed. I will set up another rule that says when the sensor reports being closed, turn OFF the LFM 20 relay. So essentially, it saves me from having to push the Off button on my phone. I’ll be able to hit On for the LFM 20 Relay (which you can nick-name something easier to remember like Garage Door), which opens the garage door, which makes the sensor report an open status, which triggers the rule that turns the LFM 20 Relay back off.
There’s a few of sites I wanted to thank, which helped me accomplish this setup. The first two I think are the same guy because the diagram is the same. If you didn’t notice, my setup isn’t the same as his, but his diagram did help my thought process a bit:
