When I first set up my smart home, the only sensors I could find were the clunky white ones that stick out like a sore thumb. This sensor is exactly what I had been wanting! It works great so I wanted to share my experience. The packaging feels significant. It is thicker cardboard and comes with very well written instructions.There were two magnets on the back and no buttons... so I figured I would read the directions before setting it up. To get it in to pairing mode, you just remove the two magnets that are taped to the sensor and it automatically goes in to pairing mode. I have never used another device that worked this way and it worked well! There is a tiny LED light on the front of the sensor, in the middle of the star looking symbol, that is used as an indicator. I ended up installing the sensor bar on the top of my door with the tiny square magnet stuck on the trim. I am so happy I don't have a big white box sticking off the front door and trim anymore and my wife is happy now, so... happy life. The sensor is now invisible to me and my guests and I'm really happy about that! I use this sensor several different ways with my Smartthings hub. This sensor will automatically turn on my lights over my front door when it is opened, I can also arm my Smartthings alarm so if this sensor is opened while I'm gone it activated a siren, turns on every light in my house and alerts my phone. As far as the installation instructions, they were very detailed and encouraged very careful planning because the sensor components are pretty small and require pretty exact placement. I am not a careful planner, so I kind of winged it and tested it and it worked great for me! Line up the star symbol on the metal magnet with the star on the front of the sensor bar so it properly detects open/closed status. The magnet must be within 10mm for this sensor to work. The overall height of the sensor is about two credit cards stacked on top of each other, so check that you have enough clearance on your door! Here are the exact dimension of the product: 7.7"L x 0.6"W x 0.12"H magnet: 1.2"L x 0.43"W x 0.04"H If you need an invisible sensor on your door or window, this is the one to get! I'm very happy with it! check out the before and after pictures!

    5.0 out of 5 stars Probably the nicest door/window sensor on the market
    Reviewed in the United States on October 3, 2016
    Verified Purchase
    Using this with my Aeon Labs/Aeotec Z-Stick Gen 5 and Home Assistant.

    From what I gather, this is a new product to the US. It seems that it's been around for a little bit in Europe, and luckily support for it has already been added to Open Z-Wave. In my setup, I am running Home Assistant on a PINE A64 Single Board Computer (like a more powerful Raspberry Pi) and Home Assistant uses Open Z-Wave to communicate with my Z-Wave network. The Z-Stick is my Z-Wave controller. So basically, as long as Open Z-Wave supports a module, it's supported in my setup.

    Anyway, the module itself is really nice. Construction is solid, and it's very very thin. Includes 2 magnets, one is for the inclusion process and the other as part of the sensor. The sensor and the magnet used both have adhesive pre-applied, so you simply clean the area, and stick. Pretty simple.

    Range is rated at 130-ft, which is quite a bit further than I needed. The sensor updates in less than a second, which is plenty quick enough for me to know if my front door gets opened.

    Only cons I can come up with is the fact that the battery is rated for 10 years, but the warranty is only 1 year, and the price. This is one of the most expensive door/window sensors on the market, if not the most expensive. I'm not saying it's not worth the cost, but it's expensive enough that I can't consider this a standard door/window sensor for all my exterior doors and windows in my house. It really is well made, though.

    Mine is mounted on my front door, which is solid wood with glass. It's the original door for my house, which is at least 70 years old. I was able to put the sensor on top of the door so it's not visible, and it works without issue.

    Really happy with it.

    3.0 out of 5 stars 1% battery after 2 years
    Reviewed in the United States on January 5, 2021
    Verified Purchase
    These are great little things for monitoring the open/closing of a door, cabinet, or other swing opening. The only problem I have is that they aren't quite sensitive enough to account for doors warping due to weather. I have this on an interior set of french doors. It's purpose with the smartthings hub is to turn the lights on when the door is open and turn them off when the door is closed. Depending on the temperature and humidity, the doors evidently aren't close enough at times to register that the door is closed so the light won't turn off. Or if I have turned them off via the hub, it may not realize the state change and leave them turned on when I go into the room. Part of that is a smarthings issue. But increasing the sensitivity on the sensor so the magnet registered a little farther away would solve the problem.

    *** UPDATE
    I bought this in April of 2019. It's down to 1% battery in November 2021. These really need to have a rechargeable battery. What I would really like to see is a recharge circuit that lets me just set it on the device I use to charge my iphone. That way they don't have to have room to add in a usb jack. Without being able to recharge these and with a battery life no where near what is advertised, These should cost a lot less.

    1.0 out of 5 stars Just not that great, certainly not for the price.
    Reviewed in the United States on February 4, 2019
    Verified Purchase
    Worked great when it wasn't installed and was placed right next to the controller.

    Put it on a door no more than 50ft from controller and the the thing is really inconsistent. If it hasn't been tripped for awhile, the sensor will not wake up on the first pass. You can tell because the light does not illuminate.

    This could be related to the fact that the "tripped" message has become inverted with being not tripped. I researched this issue and found one mention saying that support told them to unpair and then pair again. Unfortunately this did not work. What's weird is I didn't have this issue when I was using the strip next to the controller., it only happened after sticking the thing to the door.

    There was a warning that if the sensor is near a repeater, then the device's battery life could be negatively impacted because these devices work more efficiently if they are directly connected to the controller. My other remote door sensor is outside and well past my controller's main signal, I have to rely on it to talk to a local repeater, and it works great and doesn't seem to have any battery life issue. I have never heard of this precaution so I wonder if it is true or not. I cannot find any information regarding this trait either.

    We'll see how the battery life goes but the strip does is not giving battery feedback to the controller. I have another cheap battery powered z-wave door sensor and it doesn't lack this feature. I feel like for the price of this unit, that should be implemented. Instead you have to use the trip magnet to see if the light will illuminate, but that won't help you get ready to know when it will die.

    During my unpair attempt, the plastic case cracked. For some reason I could not reset the sensor without removing the strip from being attached to the door. I don't know if this is an anti-tamper feature, there was not mention in the documentation or online info. Since this sensor has no separate mounting bracket, the adhesive backing was too strong and the housing cracked. I had to tape the plastic cover back on.

    Another thing that calls into question whether this thing is fully developed is that the round magnet, which is used for resetting and waking the sensor, seems to work better at tripping the switch. The thin strip, seems to not have enough magnetic force to allow the sensor to trip unless it is perfectly aligned. I am saying this based on following their instructions, I have the thin rectangular strip magnet just about touching the flat side of the strip.

    2.0 out of 5 stars Expensive, disposable sensor with 3 year battery life. Support unresponsive. Buy something else!
    Reviewed in the United States on September 13, 2021

    It worked while it lasted but battery only lasted 3 years. Nowhere near the 10 years claimed. All my other contact sensors are still at >90% battery life after 3 years and their batteries can be replaced for cheap. This sensor is extremely poor value for the money! Buy something else that has replaceable batteries.

    5.0 out of 5 stars Excellent Sensor, Long Battery Life.
    Reviewed in Canada on August 1, 2020
    Verified Purchase
    I installed one of these on my front door when they first came out in 2015. My door is metal, but I replaced the small magnet that came with the strip with a more powerful rare earth magnet. Connected to my a OpenHAB home automation set up.

    Worked perfectly from then on, when the battery was down to 25% in 2019, I ordered a replacement, but the battery didn’t hit 0% until a year later. Even then it was still working, but I replaced it anyway. It is now connected to my ISY hub, feeding into OpenHAB.

    The new one was sitting on a shelf in my basement for a year, and reports 75% battery on install. Still, should last 4 years based on previous experience.

    So, on a fairly frequently used metal front door, I got 5 years use, and even then, the strip was still working when I replaced it.

    Overall, an excellent product.

    Reviewed in Canada on December 7, 2020

    Bought three of these and like everyone else they died after a year instead of the claim 10 years. In fact the 3rd unit I purchased came at 60% so I had the reseller replace it with fresh stock which arrived at 100%. Even it failed within the year. These are pure junk! Save your money and buy something else. It is too bad since these are perfect for patio and garden doors staying out of site. But as many others said they need a design revisit as the batteries fail too quickly for the price. Worth noting I didn’t arm the sensors except when leaving the home which was infrequent (retired).
    In closing I give these a rating of 1/5 and only because the idea has merit. The reseller was helpful with replacing the one unit so I would give them a 5/5 for service.

    3.0 out of 5 stars Works well but short lifespan
    Reviewed in Canada on July 29, 2020

    Installation in my OpenHAB system was simple enough. My sensor was mounted outdoors and I got reliable open/close events from a moderately used gate.

    After 18 months, battery level is down to 25% which means it’s time to start shopping again because the battery is not replaceable. Instead of the advertised 10 years, I would be hopeful if I get 2yrs.

    I will likely be shopping for a more maintainable solution.

    First the likes:

    Very thin, great for sliding closet doors.
    Very reliable (for as long as it lasted).
    Paired promptly with my Hubitat C-5.

    Unfortunately:

    It was very expensive for a contact sensor. I suppose I can live with that given the niche I required it for.
    This lasted 40 months in a warm, interior home environment. In my case the cost works out to $21/Year. If I had to spend that much on every contact sensor in my home, automation would not be affordable.

    These are just not practical in their current form. If it truly had a 10-year lifespan I would have few or no complaints.
