I attached mine to the bottom of the garage door. It seemed pointless to put it on the door frame! The screen goes up when the door goes up. Makes sense, no? ;)

I had the exact same thing happen when I had two. I finally had to turn off my motion sensors and everything else works great. When I had the two sensors turned on, it would also send alert that the garage was opened, but since turning them off, I have not had that issue either. I have not tried (though now I will) to only keep one sensor on while the other remains off.

I have two of these. One on each side of my garage door and they do go off randomly at night. They come on together no problem but then at random times one or the other will go off and then turn itself back on just as randomly. So far I have not noticed that they both go off at the same time but I don't stand there and watch all night either. When I first put them in and flipped the light switch on at night they blinked several times but then came on and stayed on, but now I have this random on and off thing going on with them. Anyone else have this happen?

As long as you have the two pieces properly aligned when the window or door is shut, it will not sound if when it is on. I use one on my outside garage man-door, a door I don't use, and I leave it on continuously, the battery is over a year old and still going strong.

I have 2 garage doors so I had to buy 2 separate remotes. Each door has a different programming.

One module will do two windows up OR down. You need two module to do 2 windows up AND down. If your alarm has an accessory input, it should accept this module.

April, I suggest you call the manufacturer. I can't remember, but I don't think the 'screen window' opens. The cabana is all rolled up in my garage and a little hard to get to.//Joan

True The LiftMaster is designed to raise and lower your Garage door that has a Torsion bar spring. It mounts on that torsion bar on either side of the door. It actually rotates the torsion bar to raise or lower the door. They work great, easy install and setup. I highly recommend it.

The LCD screen has gray colored background with black numbers. When I use it in my garage I have no problems reading the numbers.

You guys are really missing something simple. The garage door opener knows where it is because it has an encoder inside the unit that counts how many times it rotates past an electronic eye. It know the direction it is moving as well. So when you close it, it starts at 0 rotations and when you open it, it knows it takes 700 (pick a number) rotations to reach full open. Rinse and repeat. You guys crack me up with having to install it while the door is closed. These can be adjusted slightly (probably a foot either way) with the side knobs but not infinitely. How did you think the garage door opener knew when to stop when it was open, or when to stop before slamming into the ground? You guys are really missing something simple.

Close the panel door and hold it down for 4 or 5 seconds. The LCD will go from MAN to AUTO. :)

The garage door is normally closed when you install the garage door opener. So when you open the garage door it knows....

Maybe this reading might help a little, http://www.garagerepairutah.com/garage-door-opener-open-close-problems/ Door openers know their state, and it's not based on the eye sensors or anything like that. When you click the button on your remote, the entire assembly knows if it needs to open, or to close, or if it is in the middle of one of the operations. I can assure you from hundreds of customers using this specific button that is internet connected, their phones know quite positively the status of the door. It updates and even shows confirmation once it is in that other state. If you're on the fence about getting it because you just don't understand how it works, go ahead and get it and let it surprise you!
