Nexia Z-Wave Doorbell Sensor, DB100Z

Initially, at least, it seems to work okay for me with my SmartThings hub after adding (and "publishing" to myself) a fellow SmartThings user's custom "device handler" code to my account on the SmartThings web site. The device itself is small, neat, and very simple to install (wire to chime and mount on wall). Having it recognized by my SmartThings hub was easy, too, but that is probably because I was careful not to even put batteries in it until I added the device handler code to my SmartThings account.Since I haven't found any other product like this (so small, neat, and simple) I'll give it 4 stars tentatively, but I might change that after more experience with it. In my first day's testing the only imperfection was that I sometimes after it had been idle a long while I saw it take two (or once three) doorbell presses before it triggered through to my S-T app, but it was fine with single-press for at least a while after that; I don't know if the first press miss was due to a S-T hub (+ custom handler) miss or a sensor miss or some random thing due to S-T's internet dependency. If the combined system never missed a single quick press I'd probably have rated it a 5, but for now I'll say it seems very good despite the couple of missed single-presses and I really do appreciate it, so . . . 4 stars.FWIW, if I press the button quickly several times in a row I've seen it stick on "ringing" until an auto-timeout cleared that several seconds later, but that shows good thinking in some code somewhere.Note that this works on a single doorbell. If you have separate front and rear (or front and garage) doorbells wired to the same chime (e.g., ding-dong for front, ding for back), you'd either have to rewire them together so both ding-dong indistinguishably or would need a 2nd sensor wired to the other doorbell terminal in your chime.Be sure your doorbell wiring transformer is powerful enough. At first my doorbell's old 10V transformer was too weak to drive both my chime and the added sensor (the bell was very weak and the added sensor didn't sense), but it seemed to work very well once I upgraded the transformer at my house's electrical panel to today's standard 16V (I got one strong enough to push 2 or 3 chimes). (The instructions say "greater than 14V AC" and a table in it says "14 - 40V AC" but there's no mention of whether or not it requires more Volt-Amps than the # of chimes and length of bell wiring you already have already require so I don't know what's really required.)

This works perfectly with my SmartThings Hub (version 2). I was able to associate the zwave device after adding the two AAA batteries and pressing one button on the Nexia. Then once I associated, SmartThings recommended using their "button controller" smart app. There you're able to choose this device as the sensor, set a "custom message" text field, and then under "push notifications" choose both "pushed" and "held". Then hit "next" through the other three buttons in the button controller smart app. This app was written to support the Aeon (sp?) Mini-mote (which I have 2 of and work great by the way) and so it has the option for a total of 4 buttons but just use the first.You do NOT need to add custom smart apps to get push notifications of the doorbell press as you see in many reviews of this thing and SmartThings.You do however need to have a 14 volts AC (up to 40 volts AC) transformer. I luckily had the door bell switch 2 conductor wire and the bell two conductor wires both coming to the transformer, so it was easy to find out how to wire mine up at the transformer and avoid an "ugly" extra device mounted up by the doorbell in the hallway. Much improved WAF ( wife acceptance factor).

I have a smart doorbell and couldn't for the life of me figure out how to get a signal to my home automation system in a timely fashion. So, I found this and it's been working well. I have it connected to HomeSeer 3 via a SmartStick+ Z-wave interface.It would have been nice if this device, like the doorbell, could've taken its primary power from the low voltage line it is connected to. Instead this takes a battery. Fortunately it appears you can get low battery notifications from the device.

Best doorbell sensor on the market. Worked great with my old, standard doorbell and Samsung SmartThings (+Device Handler).With this sensor, if someone rings my doorbell, depending on complex conditions, several things happen. 1. receive text message. 2. front door lights and living room light turns on after sunset. 3. if my phone is present, pause Roku and change input on TV to front door camera (using harmony hub).Overall, it works just how I wanted it to. I installed a old-work device box recessed behind the drywall and doorbell, which ensures the sensor is hidden.03/04/2017 Update: For those wanting to use more complex rules with Smart Things, I would recommend the Smart Rules app for iOS.

This device isn't designed well to work with normal household doorbells. If you have a normal household doorbell, this has a 30% chance to work depending on your existing hardware.Once I got the device hooked up to the Z-wave network, I noticed it wasn't sensing any doorbell rings. I dug deeper and found out the device only works when the doorbells transformer provides 14 to 40 volts. Normal homes are supplied with a 16 volt transformer that typically provide somewhere beteween 10 and 16 volts. This means that they only have 2 volts of overlap where the two devices can work together. If you are lucky and your transformer provides greater than 14 volts, then you are good to go. If you are like me and you're only getting ~12 volts, you are out of luck.I have no idea why this company decided to design a product meant for doorbells when they don't account for all the doorbell configurations. Some doorbells only use 8 volts. What were they thinking?

Device itself was easy to install and works great - only problem is the fact that it goes thru battery power way to fast! At best, I get about 4 months use every time. Not good because it's installed in a vacation home and also to change batteries is up high by doorbell equipment.

Works great with smartthings. Nice and simple. Wish it could use the doorbell transformer for power but oh well.

Not Z-Wave.
