I'd like to hit a button on my car's built-in homelink transmitter and have that tell my (crestron) control system to do something.
I don't see anything for "homelink" on Crestron's website--is there a homelink receiver with a cresnet interface, or a receiver with dry contact output(s)?
I don't know if Crestron provides anything but if all else fails perhaps you could add an X10 module and let Crestron respond to the X10 command.
If you have a Crestron RF Gateway and one of their remotes, you can try teaching HomeLink a code. The Crestron RF protocol is fairly complex but is OOK and 434MHz so the HomeLink unit can probably learn it.
Otherwise you can teach it an X10 RF code (requires an X-10 RF remote) and use an X-10 transceiver and universal module (dry c> I'd like to hit a button on my car's built-in homelink transmitter and
I've done this, but for wireless remote control for a retractable outdoor awning. You can use a Lutron RF Visor Control Transmitter (HR-VCTX-SW) and a Lutron Visor Control Receiver (HR-VCRX-SW); the receiver is HomeLink compatable (so you really don't even need the transmitter) and provides four (4) dry contract closures.
You can use this even if you don't have a Lutron lighting system.

You still need the transmitter to train the HomeLink unit.
