Does NOT work with other zigbee compatible systems at present as the programmers @ Scout have chosen to use a proprietary zigbee stack. So- no Smartthings, and not Vera or the Lowes Iris. I may have gotten a defective one as there doesn't seem to be any magnetic attraction between the two halves. i don't know how a door/window sensor would work without this feature. Scout says that they are planing on their system working with Smartthings in the future- but that doesn't mean that their unique components will be cross compatible with ST without the Scout hub.
Disappointing. Waited 6 months for this and back it goes.

I wish I didn't buy this.  There is absolutely no reason for this plug not to work with HomeKit, or any other service that can bind devices from other vendors besides Amazon.  It works, but fails to integrate into the 15 other devices I can own and control using other apps than just Kasa.  I maybe should have considered the Alexa but I didn't.  TP-Link needs to wake up and set up the API's right away.  I don't think I can buy anymore devices from them until they actually build a platform that the rest of us can stand of.

It works as advertised and if you are replacing an existing opener like I did, it literally takes 5 minutes to set it all up.

Now for the benefit of Frontpoint Security customers: this device can not be integrated into your home automation system because it is not z-wave compatible. I assumed it would be since it is prominently displayed at their backend support site alarm.com. So, I have to use Liftmaster app just for the door.

Could not get this to work with my Smartthings hub. I searched online for different device handlers but none of them work. Features  and details states "a device handler required.  See installation manual below " there isn't a installation manual below.

The router has issues with load, I'm using Almond+. It drops and freezes connections often. I use the smart hub for zigbee, zwave, and that works. Also has a rule to reboot the router several times a day to deal with the router issue.

Replaced my wemo plugs with this to free up my wifi connections, works with Hue, Wemo, and Wink Hub (tried and tested)
Smartthings Hub was able to detect but you won't be able to contol, which is sad.
I end up using Wink Hub because its was able to be detected by Alexa Echo.
Note to reset the device, you must hold the power switch before plugging and release once you hear the clicks. (this i discover myself, this is not mentioned in the box and website support and till now not getting any response from osram on this how-to)
And yes this is a 220v device, not sure if will work on 110v

Had to return these as they disconnect daily.. support told me to move them closer to the main unit (they were already only 20ft away), but if I move them any closer, it defeats the purpose of them being "remote" sensors.  I'm sure they work fine for other users (as they seem to be very popular and get a lot of great reviews) but in my house there must be too much interference.  I do have a lot of z-wave devices in my house.  Perhaps if they release a new generation I'll give it another shot.

Update 1/10/2016: back to having problems again. I have noticed it will work for a few days and then quit sending the updates. Reading through other sites, reviews, and community  posts, it appears that a good amount of people have problems with Zigbee devices. Maybe it's not just these snesors. They aren't worth the aggravation, or the money being charged. I can not recommend them. For disclosure, I do have a powerful WiFi router, but it is not near the hub. Also, my Hue lights are connected to the Hue bridge, not directly to SmartThings. Take a look at the logs. I can assure you my doors have been more active and not left open hours.

Update 12/25/2015: ok, so it's been a few days and the sensors have been working with no problems.  I have even tried opening and closing the door very fast to see if it would jamb the signal.  Temp is updating when active and on changes.  I am updating my review add it appears to have been a problem with Zigbee channel interference. My hues are working and these are working great.

Original review below:
 I bought 5 of these from another site on sale. First off I was very surprised at how small they are. They also come with a battery which was great. As far as my experience, none of them paired out of the box. I followed the directions exactly (which is not hard- click connect new device, then remove the battery pull tab).

It took me about 20 minutes to get the first one to pair. I had to remove the battery a few times, which is impossible without a thin, flat object to pry it out with, Then it says to hold the connect button and insert the battery. That was fun as the connect button is extremely small and the battery is just as difficult to get back in as it is to get out.

So after I spend all this time getting just 1 to pair up, I then install it on my door with the included tape (they also provide screws and a template). It registers movement, temperature, open/close - Great we are in business!

I open the door after installing and it still says its closed... I left it sit for a bit thinking maybe it needed to sync more or something. I open the door an hour later, still says closed. So I remove the sensor from my hub and go through the fun pairing process again. With the same outcome.

I tried this on 3 different sensors, and they all had the same problem. So maybe I just got a bad batch, but something isn't right. All these glowing reviews seem off.

This can NOT connect to existing Zigbee or any other network or gateway. It can only control up to 6 light directly.

I have one of these at work, with a Z-Book 15 G3. Very disappointed. The system is unable to detect / initialize the dock peripherals unless it is undocked and re-docked (unplugged from the Thunderbolt port) in a very specific sequence. My expectation as a customer and end user is that the hardware is designed to function with humans in mind, and the hardware should be capable of re-establishing correct operation no matter how it's docked or undocked. HP has posted a "best practices" to be used with this component. I find this approach to solving the problem unacceptable.

Bought it and found out it does not support middle potision ( 0 ) in three position dip switches, so I cannot use it. The "solution" according to the manual is to change dhe 0 to + or - in the garage receiver, which is BS as I can't reprogram all the other people's remotes

I purchased this detector since it claimed to be compatible with apple HomeKit. I was leaning heavily towards buying the NEST smoke/co2 detector since it has received much better reviews, however I chose the onelink for HomeKit compatibility. Heck the one link even had the HomeKit logo on the front of the box. Well it's been two months since apple released their latest software, ios10 (of which over 70% and growing of apple phones are currently using) but first alert still have not updated their detectors firmware to be compatible. Apple has a bata testing period of over 6 months for manufacturs to update their firmware. Wake up and get to work First Alert!! DO NOT BUY THIS UNIT IF YOU USE APPLE PRODUCTS!!!!

I was never able to have the group controlled by SmartThings except when reverting to the older app and adding custom code to my hub. The "standard" color coordinator app does not work. Lag time is too much, had higher expectations for your brand name. Switched to the iLinktek smart led that works much faster and has some extra features (bluetooth color show).

This bridge may work well with other wireless products, but it is absolutely incompatible with the recent Apple Airport Extreme 802.11ac base station.  It can see the network, and join it -- briefly.  Then it causes the Airport Extreme to reset, causing all connections on the wireless network to drop and knocking all devices on the network offline for a minute or so.  Then, when it tries to reconnect, the whole cycle starts again.

In short, adding this device to an AEBS-based wireless network kills the whole network.

I don't know which device is "at fault", exactly, but I don't care.  The AEBS has been fine and continues to be fine when the WUMC710 is not on the network, so I'm returning the WUMC710 and I'll be looking for an alternative bridge product.

Very disappointed that this remote cannot setup or function at all because it will not communicate with my Cisco, Apple nor Verizon Wi-Fi... ridiculous

Very disappointed in this product. After installing it I realized that the only way connect remotely is through a Zigbee hub. This was not at clear and now I've had to spend $100 buying a Smartthings hub. It was either that, or remove the already installed lock and return, which I didn't want to deal with at that point. Bottom line, if you're looking for a connected lock out of the box, which I was, this is not it.
