Leviton DZ15S-1BZ Decora Smart Switch with Z-Wave Plus Technology, White/Light Almond, Compatible with Alexa

This Leviton DZ15S-1BZ Z-Wave on/off wall switch - in my experience - is a reliable product that works exactly as designed. Over the past 3 years I have installed over a dozen of these switches (most with the companion DD0SR-DLZ remote switch) and all continue to work without problems (*).Installing these switches in a 3-way setup (with the companion switch) may require a deductive process to (a) figure out how the original 3-way switches were wired to each other, (b) which outlet box carries the hot and neutral lines from the circuit breaker box, and (c) which outlet box has the cabling to the load. I suspect several of the posted "does not work" reviews are the consequence of the installer not figuring out how to correctly wire this switch, which also includes figuring out how to provide this switch with the required neutral connection.There is a very audible "click" when this switch is turned on and off either directly or by the companion remote switch. This "click" comes from the relay inside the switch, and not the switch paddle. Just be aware this is normal for this switch, and some reviewers have found this to be annoying.(*) If you have purchased this switch after 2019 you will likely receive one with the latest version 1.20 firmware. Switches with firmware versions prior to 1.20 exhibit unpredictable behaviour (as pointed out in some of the earlier reviews posted here) such episodically losing communication with the Z-Wave hub. It is not possible to determine from external inspection which firmware version is installed on the switch - this can only be determined by looking at the detailed device status display provided for some Z-Wave hubs. For users of the SmartThings hub, you need to use the SmartThings web browser IDE interface - this status cannot be seen using the mobile app. If your switch is demonstrating these problems, or if you know your switch has a firmware version prior to 1.20, call Leviton technical support - they will provide (free of charge) a USB Z-Wave stick and the firmware update software required to fix this problem. On switches with firmware version 1.20 (which is on all Leviton Z-Wave switches now being shipped) this switch will work very reliably on a Z-Wave network.

This is my 46th Leviton Z-wave device (39 switches & 7 outlets). Unlike WiFi switches, which seem to have no end of issues, Z-Wave devices works first time, every time. They are easy to wire, program quickly, and are stable over the long run. I started saving some by buying from the Amazon used store. The devices arrive in great condition and work, just as brand new. One tip to others, to help avoid a return on used Z-Wave switches & outlets: Do a full factory reset BEFORE following the standard directions to include the new device in your Z-Wave network. Reason: If the person who returned the device to Amazon had tried to include it in their network, it will not integrate with your system until you do a full factory reset.

Si bien conosco la marca Levinson, en esta ocasión he sufrido de una gran decepción. El producto se instala relativamente fácil, sin embargo a la hora de hacer la sincronización con la red, no aparece. Se instalo en sustitución de otros apagadores/switchs pero no sé obtuvo el resultado esperado. Desafortunadamente pediré el reembolso

I bought these because I needed some simple smart switches for non-dimmable lights that could be used in three way configurations. I also needed a switch that was compatible with existing Wink hub and Alexa. After some research I settled on these Leviton switches because they met all the technical requirements and Leviton is a well-known electrical switch manufacturer (vs offshore stuff of varying reputation)Installation was fairly straightforward. As usual, you need a neutral (white) in the box. The switches are fairly wide and deep so make sure you have enough room in the box to contain them and any wiring.Configuration was fairly easy but complicated by the Wink software being glitchy (this is, I suspect, Wink's fault so not blaming the switches here). After setup the switches have worked well, both as physical switches and also when controlled remotely by Alexa or Wink. The LED locator light is also nice at night.Two subjective complaints:1. The switches feel kind of cheap - it's a light plastic rocker with a clicky microswitch to activate and it just doesn't feel very high quality. I have Lutron Caseta switches for dimmable lights and they just feel so much nicer to use.2. Switching on/off (either with the switch or remotely) uses a relay which makes a fairly prominent click. Other brands of switches do this without a noisy relay so it just feels 'cheap'Overall, good, functional switches but a bit lacking in the 'feel' department.

I have one other Leviton device and it is at the far end of the house. It disconnects and has to be reconnected to my Wink hub periodically. Last week it disconnected again. Being house-bound due to the Corona Virus, I decided to spend some time and try to fix this problem once and for all.I went to Amazon and bought this and installed it at about a halfway point between my hub and the older installed Leviton switch, so that the Z-wave at the far end of the house could make a better link to my hub with this as a 'bridge' device.In wiring it, the Red terminal has to go to the load - I incorrectly connected the load to the white terminal at first, and then found my error and reconnected it properly. You need a Neutral wire in the box connected to the 'White' terminal to use the switch. (Hint: You can go against code and use the ground wire as a neutral if the box does not have a neutral, if the switch is not already on a ground fault, as the ground wire is exactly the same polarity as a neutral wire).The difficult thing for me was linking it the new Leviton switch to my WINK hub. You have to put the hub in the linking mode, which is not hard to do with the app on my Android phone. You then have to depress the Leviton switch (either turning it 'On' or 'Off') until the solid green light at the base of the switch turns on. Once that occurs, you depress the Leviton switch using the top of the switch (the 'On' portion) for seven seconds or until the solid green light starts to flash. I did this repeatedly with no success - and that was my fault.There is one more step - and that is what I missed at first. Once the green light is flashing, you have to depress the switch one more time in order to initiate the pairing sequence. After about an hour of false starts, I re-read the instructions and found that I had missed this last step. Once I discovered this (it was in the instructions provided by Leviton, but I missed it), the pairing happened in a few seconds. Whew. I followed the prompt and named the new switch for the light that it controlled.Then I went to the WINK app on the phone and selected Z-wave Network Rediscovery to 'remap' the Z-wave signal. Everything worked great. Finally I went to my Amazon Alexa, and verbally asked it to discover new devices. It found the new switch in about 30 seconds, and from that point on I could control the switch from Alexa.Finally I went to the original problem Leviton switch at the far end of the house. After putting the WINK hub in the pairing mode, I first disconnected that switch from the WINK hub. I then went through the Leviton 'Reset' process (which consisted of putting the switch in the flashing mode and pressing the top of the switch several times). I then went to the WINK app and disconnected that switch from my WINK hub.Once that was done, I reconnected that Leviton switch to the WINK hub using the same sequence. I used to connect the new switch. I named my original switch by a new name just to be certain that Alexa would not be confused. I am not sure if I needed to do that or not, but I did and it worked great. I then used the Zwave Network Rediscovery option on the WINK app to make sure that the original switch was using the optimum path for its signal (there is no way to confirm that it is using the optimum path - I just hoped it would do so). Finally I went back to the Alexa App and 'discovered' the renamed switch. Now everything works great.In summary, the Leviton works fine, but it difficult to link due in part to the Z-Wave technology.I found the Moes brand switches (they do not use Z-Wave) to be less expensive and far superior if connecting to a 3-way circuit (you only need to replace one of the 3-way switches with the Moes brand - incredibly clever technology by the switch designer - and although Moes had some bad reviews on Amazon, Moes has worked reliably for me for over a year wherever I installed it, and installed three of them). But once you have started with a Z-wave, you have to use other Z-wave devices to set up a decent network.Hope this info is helpful to others who have selected Z-Wave.
