With Door / Window Sensor Gen5 attached, you can do more than simply monitor entranceways and windows – you can build powerful home control and security automations.

Door / Window Sensor Gen5.

Z-Wave Plus.

Aeotec's Z-Wave Plus products are built upon Gen5, our exclusive Z-Wave firmware which enables products to offer optional layers of additional security, reduced power consumption, and strengthened wireless signals.

Scene trigger

Door / Window Sensor Gen5 lets your Z-Wave system better manage the ambiance your home, whether that’s lighting or cooling or anything else, by understanding when doors and windows are used, closed or opened.

The power of knowing.

Aeotec’s Door / Window Sensor Gen5 brings powerful intelligence to any object that you attach it to. Doors. Windows. Cupboards. Whatever it is that opens or closes, you can keep an eye on it whether you’re home or not.

Simple to install.

Security and intelligence simply.

Door / Window Sensor Gen5 is the sensor that can be installed in moments. Using either the provided screws or the double sided tape, you simply need to affix its 2 parts on a door or window and its frame. From there, pair it with your Z-Wave system. It’s all setup in moments.

Protects itself.

Just because it’s easy to install doesn’t mean that it can be removed without anyone noticing.

Door / Window Sensor Gen5 monitors itself to make sure that it’s always working – it also monitors itself to make sure that no one attempts to move or remove it. Should that happen, Door / Window Sensor’s inbuilt tamper detection system will send a notification to your Z-Wave network and any of the devices you connect.

Product Description

Aeon labs door/window sensor Gen5 is a battery-powered Z-Wave magnetic contact door/window sensor. The D/W sensor will send radio signals up to 5 associated Z-Wave devices within its own Z-Wave network when the main unit separates from the smaller unit (I.E. The door or window it is attached to is opened). bidirectional mounting plates and a push button release clasp allows for easy end-user installation. The Aeon labs D/W sensor also has tamper prevention capabilities and low-battery alerts. The sensor is 20% smaller than the first, and also includes the latest stable Z-Wave technology including Z-Wave explorer frames.

WARNING:

CHOKING HAZARD -- Small parts. Not for children under 3 yrs.

After trying a bunch of various z-wave door sensors with my Piper NV, these seem to be the first ones that don't end up triggering a ton of false alarms. They were super easy to install and set up and it's nice that they use regular AAA batteries, rather than the CR123s that other brands favor. In my setup, my Piper NV is within line-of-sight of both sensors, so your mileage may vary, but they seem to be working great so far after about 9 days of use!

Excellent door sensor. Very good sensitivity and tolerances. Works perfectly with Home Assistant.
Reviewed in the United States on June 9, 2016

UPDATE (5/2018: after 11 months of use): the batteries I installed last year just died. I think I am getting a more or less a year out of one pair of AA batteries. This time the batteries died more gracefully without falsely reporting that "door is open". Could have been some other issue last time?

UPDATE (6/2017: after 12 months of use): the original battery just died! So 12 months on one set of batteries -- that is pretty good!
However, the battery died in a somewhat dangerous way -- the sensor just started reporting the "door is open" every hour randomly even though the door was closed. I think it is dangerous so I am taking one star from my rating. I was travelling when the battery died so no one was at home for a week. I am REALLY glad I didn't wire a siren to respond to "door open" events when I am away - my neighbors would have gone crazy.

----
UPDATE (4/2017: after 10 months of use): the original battery still works fine. I am very surprised!
The door is opened at least several times a day. Over the 10 months and every day use: there are ZERO problems with detecting an open door event. There were 2 instances when it failed to detect the close event and thought the door was open when it was in fact closed (I attribute those to RF interference) - so it works with ~99.9% accuracy.

Original review:

This is an excellent Gen5 sensor. (make sure that you have a new Gen5-capable zwave controller!)

Pros:
* Super-easy to install (you can use either screws or double-sided tape: both included)
* Great tolerance: it allows for up to 2cm (~0.8") gap between before triggering!
* Gen5: can be paired as a secure device

The ~0.8" tolerance is exactly what I was looking for!
My door design is such that the door is "sunk" into the door frame. So the magnet unit and the sensor unit cannot be perfectly aligned next to each other between the door and the door frame since the door frame sticks out.

I never could install any door sensors on my door until I got this one!

The gap between my sensors is well within the tolerance of this unit and I get very reliable detection of door opening and closing.
Connected it to Home Assistant and it is working perfectly now.

Other comments:
* 2 AAA batteries are included into the unit
* to pair you need to open the battery compartment:
- don't confuse the button on top for Z-Wave Action button. Z-Wave Action button is inside. The top button is just for opening the battery compartment

Overall, highly recommended if you have a Gen5 capable controller.

Aeotec Gen 5 ZW120 not Reliable
Reviewed in the United States on September 26, 2017
Verified Purchase
I have 11 of these that were successfully installed over the last 18 months on 2 rental properties to turn on and off the HVAC systems. I originally tried Fibaro, but they failed in less than 30-days. There is a high failure rate out of the box (perhaps 20%) of the Aeotec Gen 5 ZW120, where the device will not sync/add into the system. Amazon always allowed a return without question. Also the batteries supplied drain very quickly. Now I find the sensors that were installed about 12-18 months ago, stick in the open or closed position occasionally and are unreliable and must be replaced. Since these are beyond the 30-day Amazon return period, I bought 5 replacements. One would not add into the system out of the box and now after only 3 days another one will not reliably indicate open and closed. The factory, while good about taking calls, does not have a solution. Unfortunately, as I look at other brands on Amazon , it looks like they too are equally unreliable in the long run. Update Dec 2017--After replacing these once again in July, they are still not reliable and I had to shut off the entire Z-wave system.

Possible poor cold weather performance
Reviewed in the United States on March 5, 2017

I bought two of these. One is installed on the front door of the house. The other is on the personnel door into my garage. The interior one is working very well. Nice quick response to changes in state, good battery life ect. The other one has not updated its status since the first day it was installed. It's been about two weeks now so I decided to see if I could get the darn thing going. I moved my hub closer in case the signal was too far away. I was skeptical about this because two other devices at the same door were working fine. Sure enough, this didn't help. I removed the device from its mount and got a signal from the device pretty quick about the tamper switch (two seconds?). So the signal was getting back to the hub.

I brought the device into the house to do some testing. I had planned to remove and reintroduce the device to the z wave network. Before long, about five minutes, the device began sending open and closed status signals erratically. I grabbed a refrigerator magnet to simulate a door opening and closing. I could not get a reliable result. Maybe the magnetically activated switch was getting stuck. The tamper switch was activating in a completely reliable manner, so it was not a wireless signal problem. If I put the magnet near it, it would not show closed so I tapped on it. Boom closed. Remove magnet and it doesn't show open. Tap on it and boom, open.

I checked this procedure several times and it seemed to indicate that the switch was sticking somehow. I decided to take it apart. I found the switch inside but it is not serviceable. But then something cool happened. It started to work as expected, and reliably. Nice. I put it back together and checked its operation again. It seemed good to go so I installed it back on the garage door. I tested it a couple more times once it was up and that was it. It worked two times to indicate the door had opened and closed then it got stuck showing door open. Dang. I shut the door and looked at the smart things app and waited. About 20 seconds later it showed that the door was closed again. Pretty slow response. Additional attempts to get it to update its status while installed on the door proved unsuccessful. The door has now been left open for30 minutes and the device appears to be stuck closed again.

I'm disappointed. I believe that the temp might be affecting the operation of the door sensor. The manufacturer says that it should work down to 0 degrees celcius but not this particular one. 35 bucks down the drain.

Update: I found a workaround. I moved the reliable device to the garage door and brought the other device indoors. So far so good. Still concerned about the device reliability. I will have to replace it. I just don't have confidence in it any more.
