I have an older 2009 Nissan Titan. I remembered that it has 3 Buttons on the Review Mirror that are intended to be used to open a Garage Door. I had completely forgotten this function in the truck existed, but now I would like to finally put them to use.
At first I thought that they would work on just your typical rolling Garage Door Remote frequency, maybe some how being able to program them by pointing an existing garage door remote at it to learn the frequency/code… Sorta like you can do with a IR TV Remote.
But apparently it uses some function/service called HomeLink. I did a short amount of research on this service, but came up more confused. Being my vehicle is older (I bought it with my enlistment bonus back in 2009, it only has 32,000ish miles on it - in case anyone was wondering "why doesn’t this fella just upgrade to a new truck…lol…any hoot)… Being my vehicle is older, all the information I was able to come across seems to be for they upraded/updated versions of this HomeLink; with most likely more advanced Security protocols and whatever. “Security+ 2.0” was mentioned in several documents read, but that came long after my vehicle was manufactured, and there is no possible way it could have been updated on the vehicle since then.
I thought maybe I could just get a basic Universal Garage Door Opener/Receiver of sorts, one that would communicate with this older version of HomeLink. Then wire it some how to maybe a ESP32. Using the ESP32 on the Home Assistant side of things.
Only concern is, I’m not entirely sure what to look for in a specific garage door opener/receiver. I tried to do a google search using the keywords “HomeLink Universal blah blah” but then just got left lost in the many useless Google Search Results for product pages that seem to make no mention of HomeLink, or for pages that mention things like LM850, LM137, LM173, and so on… but have no earthly idea what all that means. (We’ve never had an actual garage door opener… we concerted the garage many years ago into a workshop, and the garage door is just manual - hence why in over the 10 years since buying the truck I never used this HomeLink feature. lol)
Anyways, I guess I was just hoping somewhere out there in sea of Home Assistant masters and hobbyist that someone had the same crazy idea to do the same thing, and might know what is needed to achieve this…
My intention in the end, is to be able to program the 3 buttons in my truck to turn on different things. One being the flood lights over looking the driveway. My truck is lifted by 6in, and has 0% Tint all the way around. It can be hard to back in late at night, trying to squeeze between the wires vehicle and the bricks lining the drive way. Two maybe unlock my front door. Though I’m not sure I’m 100% set on this due to possible security concerns. Three disabling/pausing motion recording/notifications from the 3 cameras that have an angle on the drive way. It can get super annoying when pulling into the drive, and my phone gets about 9 notifications all at once (1 for passing the “Crossing Link” 1 for Vehicle Smart Detection, 1 for Motion Detection from 3 different cameras)
