What I don't quite understand about this product is how it knows the state of the garage door, open or closed? Without a door sensor, I don't see how?

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.

Wall switch tells it what position the door is in since it usually starts out closed when you install the new wall controller.

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!

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

I was thinking this too, but it must, cause the switch doesn't have a down button and an up button, but just a single button used to go up or down. Therefore when you click the button the garage door knows what state it is in and moves the motor forward or backwards depending on opening or closing the door.

As per the other answers, I assume it is a tilt sensor in the transmitter that you attach near the top of the garage door.

It is possible. Try moving the magnet around all sides of the door sensor and see if you can get it to show as closed. You may also want to delete and then add the sensor back to the panel.

I have a remote electric garage door opener& have no problems at all, but you might want to check with Sears. This is basically an indicator light that shows when the door is open or closed without you having to go look

I have three garage doors, and believe you can set them up as one or together. Presently using two doors on one sensor alarm point and three other independent sensors. only issue so far is the mounting has to been at bottom garage doors, and battery 2031 last about 4-6 months. If false alarms show up, it is the weak batterys and most time when it gets cold out. In fact all false alarms have been weak batterys, any sensor.

Yes the app will show when the garage door is open/opening or closed/closing. Yes you can configure the alert for open and close of garage door in the app. Also can send you email for each occurrences. You can install the app on any number of smart devices with the same account.

If your garage door has a sensor beam near the bottom of the door, or a torque sensor that stops the door (if the load on the motor is more than the setting), both would stop or reverse the door. Before you blame the remote, check and make certain that the photo-eye censor is always seeing the light beam. Usually, there's and indicating light (sometimes green, but could be white or amber). Try adjusting this. By placing you hand over either end (sender or receiver) when the door begins to operate, your door should either stop or reverse.Mine has come out of adjustment and caused my door to go up.

You need to purchase the Chamberlain MyQ Internet Gateway as well as the door controls. You then set it up on your PC/network using your wireless router which will give you the ability to control your garage doors and other devices from any smart phone (App) or PC. Any door control settings ex: Min. to automatically close door, lights on/off and lights on by motion/heat sensors are only controlled at the physical controller. As far as the garage door controls remotely, you are limited to opening and closing the doors and getting alerts when doors are opened and closed. You are also able to see a timed log of all door(s) activity. *Be warned... if you install more than one of the controllers in your garage, they must be placed a min off 12" apart or the motion sensors for the opener lights (the ones you mount to the ceiling) behave erratic and go off and on for no reason at all. There is a Chamberlain service bulletin addressing this issue.

I am not sure I understand your question. Mine beeps three short beeps when the garage door begins to open, and one long beep after it is closed. There is no "alarm when door is closing".

I put the pros sensors into my sons backpacks to track them, but they could go on a keychain as well. The door sensor I have stuck to the inside of my garage door so it is pretty invisible.

The product sensor attaches to a single garage door (can be single car width or double car width). The switch sends an on/off signal to one motor control unit via wired connection. If you have two separate doors to open, you will need two of these products.

If your door opens outward I' am guessing the door is flush with the door frame on the outside. This is where the door sensor should mount. The door sensor has two pices using double stick tape to mount. I don't see how you could mount the sensor on the inside of the door because the door is not flush with the frame eon the inside. There is a motion sensor also that you could use on the inside that would detect any of the doors opening. Hope this helps

It will alert you when the door is open as well if it's opened for a certain period of time. It has rules you set. It will not distguish between opening using a remote, car or manual. Just open.

This is magnetic reed contact switch, which means both pieces must be aligned for the electrical circuit to be closed. To answer your question, it's not a sensing device. It will only tell you if your window/door is open or closed.

All of your portable remote transmitters (in your vehicles), wall-mounted keypad entry transmitters (enter a code to open/close the door), and wall-mounted door controls (on the garage interior wall) continue to work properly with the garage door opener. This product is simply another means to monitor the door and open/close the door. It does not disrupt any of the already installed accessories for your door opener or their operations. One of this product's great feature is the ability to send an alert to your phone anytime the door opens or remains open too long. You determine if an alert should be sent and under what conditions (which days, times, etc.).

You'll have to state the question more clearly. I would recommend you remove the wires from the garage door opener and remove the battery from the Magic Closer. Wait a few minutes and re-install again according to instructions. Insure your sensor is located at the top left of the garage door.

Hi Bob, there are two sensors on this model; 1) there are electric eye sensors that are mounted on the bottom of the door rails. These sensors are designed to cause the door to reverse when something interrupts the light path (like a child) so the object is not squashed. Interestingly, my dog just tripped this one about 10 minutes ago. The door reversed as it was designed and both dog and door are ok. 2) There is an obstruction sensor that detects if there is something that will prevent the door from fully closing. If the door meets resistance as it is closing in other than the full down position it interprets the resistance as an obstruction and reverses motion. So if you inadvertently left a 2x4 laying across the threshold, the door would hit the 2x4 and interpret it as an obstruction and then reverse motion and return to the full up position.
