Device detailed description

The SmartThings Motion sensor is a ZigBee device that lets you know when movement is detected in a certain area of your home and can trigger different actions in response to that movement. Set lights to turn on and off as you come and go and protect your home by triggering lights, sirens and other electronics to turn on if there’s unexpected motion in your home. The sensor can also detect temperature and trigger smart thermostats, window A/C units and portable heaters to automatically adjust as people come and go. Place the motion sensor on a table or shelf, or use the included adhesive or mounting bracket and screws to place it on a wall. The Motion requires the SmartThings Hub and has a range of approximately 50 130 feet, depending on your home’s construction. SmartThings offers a one year limited warranty on this product.

Frequently asked question

Is this switch compatible with philips hue and homekit?

I am using this motion sensor with the Hue white bulbs in my Kitchen pantry. I have the Hue bridge v2 and the SmartThings hub v2.

If i used this with smartthings to turn on a GE Zwave switch, what kind of delay is there?

Well, it just depends on the environment. I have my smartthings hub right next to my AC3200 router which are known to interfere with each other. However, in most of the cases, it works immediately. I use these motion sensors to control most of the lights in my house. But sometimes, maybe once in a week? or several days… see more Well, it just depends on the environment.

I use these motion sensors to control most of the lights in my house. But sometimes, maybe once in a week? or several days?, it lags for some reason. I haven't had time to look deeper into this issue, but yeah most of the time it works well and I can bare the lagging issues that just comes once in a while.

Is the product weather proof?

Nope. This is an indoor motion sensor. There are other weather-proof motion sensors that will attach to the SmartThings hub, however.

How are these in very very dark rooms? Is the night vision any good?

So far so good. I use them to power up room lights after sunset and can walk into a totally dark room and have it sense and pop on the lights every time.

    Very Pleased with this Motion Detector

    I really like this motion detector!
    I’m using a Samsung SmartThings hub.
    I have about 10 of these motion detectors at present.
    I started my home automation project at the end December 2015. As of Jan 19th, I have 18 Linear wt500z Dimmers, 8 wt00z-1, several Aeotec mini-mote (both original and v2), Ecobee3 thermostat, and many Cree connect light bulbs for closets, ambient light under bed, etc.
    I’m using the motion detectors to trigger lights to come on when motion is detected in closets and most rooms. With SmartThings I can specify ‘turn on light if motion and within certain time period’, luminance reading from luminance sensor, or dusk/dawn with offset setting as a trigger.
    They work as they I needed them to. They detect motion to about 15 feet. Beyond that they are hit and miss. Large rooms may require a few. I don’t have pets so can’t speak to any issues there.
    I have a couple under a king sized bed, both pointed out. They detect someone getting out of bed at night, which then triggers a Cree Connected LED Bulb to come on under the bed at about 10%. The bathroom light is also set to come on at 10% at the same time.
    I have them in the hallway for the upstairs bedrooms, no more risk of a guest falling down the stairs in the dark.
    Battery life has dropped 1% in three weeks, except for the garage sensor. I may have a bad battery in that one, it started is life at 90% and is now at 77%. I don’t know if cold has anything to do with it – temperature there is usually 20-40F.
    I have had no false positives to date, and they have always detected motion and triggered.
    This was not a solicited review – I (unfortunately) have received no free product……

    Works great! (Be warned of battery if you need to replace it)

    I’ve had SmartThings for almost a couple years now and am still using a first-generation motion sensor that came with my kit. I wanted to add another and so I got this one (the third-generation, I think–2015 version). I’ve had good experiences with previous SmartThings motion sensors, and this one is no exception. It detects motion when present and (unlike some others I’ve tried) does not trigger a lot of false alarms for me. Unlike my first-generation sensor, this one has the added benefit of also measuring temperature, which I previously used a multisensor to do. The only disadvantage is that unlike my first-gen sensor, this one does not use a common household battery size. However, the lithium coin-size battery (CR2450) it does use lasts longer than most alkalines have for me–mine just died after 16 months of use, which is much longer than any other sensor I’ve used (though the Iris sensors I haven’t had for that long yet are still going strong and I’d expect a similar life from them). Note that, unlike the first gen sensor, this one only has the option of battery power, there is no USB power option. This model is also much thinner and a little smaller than the first generation, but neither is particularly large. All things considered, this is still a good sensor and works well with SmartThings (and presumably any ZigBee HA system).
    One note: when the battery dies, you’ll need to be careful about what *kind* of CR2450 you replace it with. SmartThings says Panasonic or Duracell is required, but you can’t see this until you remove the existing battery and see it printed inside the battery compartment itself (it is on their website also, but it is *not* in the manual). Not knowing this before it died, I purchased two Energizer batteries, which do not work. The reason is, apparently, that the edge of the positive side of these batteries is a bit shorter than those on the Panasonic one that came with the device, and so the small metal part in the sensor that is supposed to make contact with it doesn’t actually make contact. They must have tested Panasonic and Duracell and found that they fit correctly. This would have been an easy fix for them during manufacturing–make the tab a bit taller to accommodate most other brands of CR2450 batteries, but it’s frustrating that any standard CR2450 won’t fit (and that it’s not clearly stated elsewhere).
    In general, these work well. The slight problem with the battery compartment and the lack of external/USB power options are a bit disappointing, but I’m otherwise happy with this sensor. They seem to have discontinued it, however, in favor of a newer model that has less than stellar reviews (though there are some of those for this model too, which I don’t understand). My new favorite motion sensor is the second-gen (purple box) Iris motion sensor, which works with SmartThings or any ZigBee HA 1.2-compatible system–they’re the least costly sensors I can find and they work great.

    Turns bathroom lights on perfectly! Off again? Not so much.

    I purchased one of these (along with the new SmartThings hub and a couple GE Link lights I already had) to control the lighting in my bathroom when it was released a few weeks ago. It works about 95% of the time to turn on the lights, which is good enough for me–I like that the lights automatically click on and dim when I stumble down a dark hallway half asleep at 2am. It also has fantastic battery life and shows an accurate representation of ambient temperature. It took about 6 tries to get it linked up to the hub though, even when I was next to the hub, but it eventually worked.
    The major flaw of this device, however, is it’s inability to correctly determine when to turn off the device it’s linked to. Turning off a device that is already on is determined with the subcondition ‘Turn off after X minutes if motion stops’. Perhaps it’s just a matter of flawed semantics on SmartThings’ part, but as far as I have experienced, the sensor only measures movement again after that X amount of time (to determine whether or not to switch off) instead of continuously after the initial ‘on’ movement is detected. So if, for example, I set the rule ‘Turn on light when motion starts’ with ‘Turn off after motion stops: 2 minutes’, the lights click on when I enter the room, but then click off if the sensor does not sense movement exactly 2 minutes after that. To make matters worse, it won’t measure movement again until another full 2 minutes have elapsed… which means that I usually get to brush my teeth in the dark unless I manually reset the system by turning the lights off and on again in the hallway.
    I’m sure this was implemented in order to conserve battery life on the device, but it would be an easy fix on SmartThings’ part to simply allow the user to set the device to reset the ‘time until it turns off’ timer whenever motion is detected. This would be a 5 star product if they fixed the pairing issues and especially the motion-stop detection. Until the issues are addressed though it’s a 3 star product at best… as I can assure anyone attempting this setup that there is nothing worse than sitting on the toilet in the dark.
