Ford Taurus Homelink Visor Integration

I used the below to successfully integrate the garage door buttons into smartthings. I now can disarm and unlock the house when arriving home.

ELENKER DC 12V 10A Relay
2A 24W Power Adapter Supply
ECOLINK DWZWAVE2.5-ECO

Brand and model of the sensor? ( some models have dry contacts and some don’t, so people usually want to know which you are using. )

FAQ: List of devices with dry contact input from external sources

Hi, I’d like to document on this forum a list of devices which have the ability to accept input from other devices. I personally am thinking of buying a Motion sensor called a Dakota which can output when it detects motion via Dry Contacts. I know of some already to start us off: Ecolink Z-Wave Garage Door Tilt Sensor Schlage Rs100hc Z-wave Door & Window Sensor If you are ok with cutting off a water sensor and cabling, this seems pretty much the cheapest option I can find globally is the Tuya water leak sensor: https://m.aliexpress.com/item/1005004384160139.html (Credit for finding the Tuya goes to legend @Paul_Oliver )

I bought the first ECOLINK DWZWAVE2.5-ECO dry contact z wave sensors in 2017. I now have 4 of them they work great and all have had the dry contact sensors. They come with both brown and white shells in the box. They can be used as a door and window sensor as well and include a magnet. They also detect tamper when the cover is removed.

To be clear - you programmed the car’s built-in buttons to trigger the radio receiver in the relay, right? And the contact sensor is triggering a routine?

[ehupp01 (Eric)]

Yes the cars built in visor button triggers the ECOLINK DWZWAVE2.5-ECO. The RF receiver comes with a transmitter that you need to program the visor button.

1. Wire everything together so that the ECOLINK DWZWAVE2.5-ECO is NC
2. Power up the RF receiver with the power adapter.
3. Press the learn button on the RF receiver and then the included remotes button.
4. In the car program one of the visor buttons with the included remotes button. Link
5. Press the learn button on the RF receiver and the now programed visor button.
6. Set Routine to Automatically perform when the ECOLINK DWZWAVE2.5-ECO opens

I also replaced the antenna wire on the RF receiver with one about two feet long to increase the range a bit. The antenna wire it comes with is about a foot long.

Very cool. I suppose the RF relay might be able to learn the codes from other garage door remotes… Keyfob clicker to unlock my front door might be nice to have.

I dont see why it could not.

[JDRoberts]

Some garage door remotes have what is called a “rolling code“ where it changes. It’s not possible to learn those, which is the point. It’s a security feature. Both the transmitter and receiver have the same encryption algorithm.

BTW, your project looks very similar to the following.

Successful HomeLink Integration

All, I found a number of posts on here with folks looking to connect HomeLink or garage door opener remotes with SmartThings, but no real good solution other than using a garage door open/close sensor on the door itself. I don’t have a garage you can park a car in, so obviously, I have no garage door on which I could use a sensor. I wanted to be able to directly trigger a routine from the HomeLink button in my car. I used some info from here and bits from other places around the internet and put together a solution that is working well for me. It was really very simple. Details below. In short, I used a universal garage door opener receiver and wired it to the contact terminals on a standard Z-Wave open/close sensor. I then used a universal garage door opener remote to program my H…

Very much the same. My inspiration came from my previous Dakota Alert 2500 integration.

Right - I assume, since it paired with the relay, the HomeLink has the capability to pair up with receivers with or without rolling code. I know my Liftmaster keyfob remote had different programming options at setup; I’m hoping one of those is also “dumb” and would work with this relay. I don’t have a compelling reason to buy one of these at the moment, so I’m not going to find out, but I’m intrigued by the idea.
