Using automobile built in garage door (RF) opener to drive HA event?

[PaulD]

Most cars now have multiple built in buttons with RF to activate garage doors. In my current auto's, you teach the garage door buttons from your normal hand held unit. Can I do the same with a RF xmitter set up for my HA system such that I can then use one of the car buttons to trigger events in my HA system?

I know I could detect a garage door opening as a trigger but I am interested in turning lights on/off independently from garage door movement.

I have wondered this as well. I have an Omni and Homelink in my cars. According to homelink they are compatible with devices in the 288-399Mhz with 418Mhz on newer cars, that puts the 433Mhz of the normal Omni wireless out of reach but perhaps the GE compatible wireless receiver at 319.5 Mhz would work?

The main thing besides frequency I am not sure if the fobs with GE security can be learned by homelink, has anyone tried?

Another alternative would be some homelink reciever with dry contacts but I have not been able to find something like that?

If you find it let me know! I have Jeeps and they too are Homelink.

if you are using z-wave this is what you are looking for http://www.wayne-dalton.com/access/access_kits.asp

i am not sure if this supports homelink however you get a keychain with the kit which has 3 buttons. the big one is to open your garage door. the 2 side buttons are for scene control of z-wave devices including lighting. you can also program any 2 buttons together for a total of 6 possible scene configurations. i have tried it and it works fine. don't expect to use your HA system to control the garage door though.

for the in car units they refer to compatibility with Car2U devices - http://www.learcar2u.com/

I use one of these for remote control commands. Just wire the dry contacts into your controllers inputs and write your code. They work great. So good, I pulled my garage door motor control board out and made my own so I can control it from my system.

I don't know if this is compatible with existing homelink systems or not.

I looked at those boards a while ago for a project and they looked great as they have the rolling code for security.

what kind of range do you get with the remote? I looked (quickly) at the site, but couldn't find the option to order a second remote...

I have the unit between my floor joists in the basement near the front of the house. I can reliably transmit from anywhere inside (raised ranch ~1800ft^2+bsmt) and about a 50' radius outside +/- a few feet. I think it's one of the best components of my system for its simplicity and effectiveness.


I think I ordred from a different site. I ordered a second remote for my wife immediately so I know somone out there sells extra remotes. I'll find it for you...

Take note of the alternative firware specs. I'm changing my chip too. I don't like the way it changes operation modes either. My wife holds the button down to open the garage door from the end of the block and changes the mode without knowing it. It doesn't matter though becaue my program looks for the rising edge of the true logic only, duh. The new firmware fixes that.


I ordred mine from here. I see they already offer it with the new firmware. This seems to be the best deal.

Homelink can send X10 codes and if your home automation package can recieve these codes you can active any events you desire. Many use RR501's and others use the W800.
