I cannot get this garage door opener to work with a new vehicle I bought. So I bought a wifi relay and I can open and close the garage door readily from my phone. But then it became apparent that I had no idea if it was open or closed. So I was thinking of using these existing limit switches as inputs to another wifi device that would indicate to me whether the door was open or closed.

Okay, so now we understand what you want to do.
To avoid messing with the switch action, just monitor the voltage on the switches with the wifi device to determine whether the door is open or closed.
Likely you need to only monitor the "closed" limit switch since that's the important thing to know.

Another way, to avoid messing with the opener, is just to add a magnet operated reed switch on the door (such as used in home alarms) which closes when the door is closed.

 

I suggest a visual approach to knowing if the door is open or closed. And the rule: if the door is closede, do not pass thru, open it before passing thru. BUT for just checking when not near the door, it does get a bit more complex.

Thank you, the reed switch was a last resort. I wanted to see if i could use the switches since they were already in place.

MB2, initially I thought that, who needs to know if it's open or closed. Ill know because I pushed the button on my phone. Then, as you know, with cell phones radio buttons can magically be activated and I had to go outside and see if I inadvertently opened the door which I did.

Another reason is that just because you tell the door to close doesn't mean that it actually closed. There are safety sensors there for a reason.

Last week I came home after going to the store and the garage door was up. I always confirm that it is closing as I leave (I don't wait for it to fully close, though, as that takes more time that I'm usually willing to spend). At first, I assumed that I had simply forgotten to close it (that has happened a few times). After backing into the garage, I closed the door and it went down and then went backup. This is not uncommon as the front of the car sticks out further than it would see based on the view from the driver's seat and there isn't a lot of excess space, so I always wait to shut off the car until the door stops moving. If it starts going back up, I back the car up a couple inches and try again. Sometimes I have to do this twice, but not often. This time I had to do it four times and it still didn't close. I knew I was back more than enough. That was then I noticed a small weed that was stuck to the bottom of the door. It extended into the garage just far enough to trip the safety sensor as the door came down.

My car has a "HomeLink" button that can be programmed to open and close the garage door. Not sure if it is called "HomeLink" but I remember when I had to program it - I had to hold the button my my remote while at the same time holding the HA button. Had to do that for several seconds, if not a whole minute. Had to make a couple stabs at getting it done, but I got it done.
What kind of "new vehicle" are you trying to get to work the GDO (Garage Door Opener)?

the reed switch was a last resort.

I'm not able to know if my door is open or closed when I'm away from home. I COULD use my home security system to look at the garage door, but then I'd have to hook up a router gateway to my system so I can monitor the cameras remotely.
A thought that has just popped into my head: I have a monitored home security system (not the cameras). Putting a door sensor like @MisterBill2 suggests will give me an indication of a door being opened or closed no matter where I am in the world. I can't close the door remotely but I can ask a neighbor to close it for me. My garage is separate from the home. Still, I have valuable equipment to keep secure.

I have been through that, Ive had success with 4 other vehicles but not this one. Thank you still.

You must have a slow opener.
Mine is closed by the time I've backed out of my short driveway.

 

Somewhere I have a schematic of an automatic GDO closer. It's time based with a programmable timer. At pre-programmed times if the door is open it will automatically close. If I recall, I had at least 3 times for closing the door. If I wanted it to stay open all I had to do was open it and stop the open process just before it was fully opened. I'll look around and see if I can find that silly thing.

No luck. Must be on an older computer.

It's not very fast, for sure. I've never timed it, but by the time I'm out of the driveway and moving far enough down the street that I lose sight of it (about 1.5 houses distant) it is a bit over half, maybe three-quarters closed. After I turn onto the first main road there is a brief spot where I can look over and see the house to verify that it closed and I usually do this, but not all the time.
