I used the below to successfully integrate the garage door buttons into smartthings. I now can disarm and unlock the house when arriving home.
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. )
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?
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.
- Wire everything together so that the ECOLINK DWZWAVE2.5-ECO is NC
- Power up the RF receiver with the power adapter.
- Press the learn button on the RF receiver and then the included remotes button.
- In the car program one of the visor buttons with the included remotes button. Link
- Press the learn button on the RF receiver and the now programed visor button.
- 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.
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.
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.
