Does it sense door open/closed?

It uses the dome light circuit to sense a door opening (covers SUV hatches too).

It senses it by the dome lite turning on. When there is a new electrical drain, it senses it and alarms

We installed our alarm system a little while ago. However if you blow up the picture, you will see both common normally closed and normally open. In other words, it does both.

It can alert you when it opens, closes, or stays open too long - you control the settings. I don't know what models it works with, but my opener was old 5+ years and it works.

i think this should work whether the door opens in our out. this device uses the hole that the door latch fits into when the door closes.

I am not sure what you mean by the door sensor. I believe the actually sensing of whether the door is open or closed is in the lift unity itself. That is why the lift unit needs to be more recent model. The LiftMaster MyQ specifies what kinds of lifts will work with the controller and the internet interface. We have HomeLink units in our two cares and have had not interface problem with the MyQ. One note, I was told that when linking to the internet you need to be using something other than MS Explorer. You can use Chrome or Safari.

As long as you mount the unit so the plunger travels in and out of the unit when the door opens and closes, it will activate the sensor.Also, I think the bottom of the plunger has a tiny wheel to facilitate non-vertical motion, as when a tilt door slides open.after reading the other response, I have to agree that caution should be taken in mounting the unit so as not to break the plunger.

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

Yes thereis. By hittinh the hold button the door stays up. Hit it again and the timer counts down from 30 seconds and the door closes

No unless you want it to dial out when set off. If you want it as a alert when a door is opened or a window works perfect. I got it to keep my teenager from sneaking out havnt had a problem since.

It is really a notification system that tells you when the door is open. When it is activated, each time the door is open the alarm will sound and when the door is closed again, the alarm will go silent. It does not have a delayed exit or entry function as in a more conventional alram system.

Yes. You can open and close the door from anywhere. Also I'm getting prompt alerts whenever door is open or closed.

It is a spring and cam type system. If the door is open it will stay open, but once you start to close the door it will pull itself closed. The mechanism in is the center behind the hinge.

It has a steel fastener that latches when the door is closed. You pull to open and close to latch.

Short answer, yes. This opener is very advanced. It has 2 sensors, one for the "down" stopping point, one for the "up" stopping point. You can move these to adjust how far the door will be pulled-up or lowered.

I had it get out of sync and show the door closed when it was opened. When I clicked to open the door, it closed. About the same time, the gateway lost communication with the door so I don't know if resetting the gateway or opening and closing the app reset the app's brains but when it came back online, it knew correctly if the door was close/open. So, jury is still out.

The only way I am aware of is to look at the app. I do not see anyway to program it to alert you the door is open.
