ENERWAVE Z-Wave Plus Relay, Hidden Smart Switch Wireless Remote Control to Lights and Ceiling Fans, 120-277VAC, 10A, Neutral Wire Required, ZWN-RSM1-PLUS, Black

this tiny device is amazing. After someone rang our doorbell - as a prank - shortly after putting the baby to sleep, which then sets off the dogs barking like crazy, I almost disconnected it (as the previous owners had done - when I bought the house I had to figure out why the doorbell didn't work). Anyway, to make a long story short, I installed this at the transformer gang box, paired it with my z-stick, and set up a schedule to automatically cut off power to the doorbell on my daughter's sleep schedule. During naps, we can just turn it off on our phones using our smart home app. Installation was easy, if you know how to install an outlet or light switch in a gang box. Pairing was easy as well - it paired on the first try. Oddly, my software - Indigo - did not find it on the z-stick on the first try, but it did on the second try, phew! taped up the aux wire to avoid shorts, stuffed the whole thing into the gang box, closed it up, and done. Works like a charm. Note: while any relay could work - I was torn between this one and the Aeon Labs one - this one has lead wires on it whereas the Aeon Labs does not, and there were comments in the reviews that getting the wires into the holes might be tight.

I have three of these Enerwave relays (one single and two duals). They work as advertised with Smartthings. I love that this allows the standard switch to continue to function normally, while also allowing for smart control. The main thing I didn’t understand before installing is how the switch behaves after install. I had a single switch so up was always on, down always off. So much so my physical switch has “on” and “off” labeled on the toggle switch. Once you install the relay behind the switch, the single switch behaves like a 3 way switch. Up and down no longer indicate the state of the light/fan. You just have to reverse the switch to reverse the state of the light/fan. I have 2 of the Honeywell / Jaysco switches that handle the position issue by being spring loaded so the toggle deflects up or down and returns to the middle. The Honeywell is much larger, and is a bit different than a standard switch. My wife was mildly annoyed with the Honeywells, but she couldn’t tell the Enerwave was installed. The Enerwave feels like the same old switch because it IS the same old switch. The dual relays function just as well with the required Device Handler in SmartThings. The pricing of the Dual relay 2 pack is better than the single on a per unit price. The Dual Relay is only slight larger than the single so I’d buy the dual two pack going forward, even if I only had one switch to control. You might reconfigure things in the future and be all set with the 2nd relay on hand. My electrician friend tells me this works with 3 way switches so long as you install it in a box with both the hot and the load. In one of my installs I did have the hot and load in the box, so both of the physical switches work and the relay works. Other scenarios I didn’t have both in the same box so I couldn’t get it to work. Let’s just say this will work with 3 way switches in some circumstances. As they say your mileage may vary. Install is on par with any switch or outlet. It’s not rocket surgery, but may be out of reach for some. Always turn off the breaker when working on anything. An electrician should be able to install this without issue if you get stuck. All things said, this is a solid addition to my Smartthings home. My new favorite smart lighting and fan automation.

Description is accurate and product seems to be a good quality. Installed two of them in two metal electrical boxes to control two attic/roof fans. The little antenna can stick out of the box and communicates well with z wave hub. However, it has a max operating temp of 105 degrees fahrenheit, so it may fail in some applications. Should also check out the SONOFF ZBMINI ZigBee Mini Smart Light Switch. They too can switch 10A, cost about 1/4 as much and have an operating temp up to 140 degrees Fahrenheit. I found those after buying this one and got four of them for $40. The max 105 degree operating temp for the relay this review is about is a big disappointment since in my application it will likely fail.

I've attached my Smart Home Lighting Guide to help people with the installation of these Micro-switches. I have a few of these around my house. They work well for someone who wants to keep their original light switches in place and want to inconspicuously integrate Z-Wave control into the switch. I didn't have any issues at all when wiring these to a single pole light switch. You just wire them up using the included wiring diagram and you're good. The inputs are low voltage since they're just wired directly to your light switch. I love that they come with pigtail wires instead of smaller screw terminals. The Aeon Labs micro switch had terrible terminals and I prefer this over the Aeon Labs switch. If you plan on using one of these in a 3-way setup you MUST have Line, Load, and Neutral all in the same box. You can't get one of these to work if your Line and Load are in 2 separate boxes unless you have an unused wire running between the boxes that you can use to carry line to both boxes. Trust me. I've spent hours trying to make this work. If that's your situation, your best bet is to either buy a GE Toggle switch with a GE Add on switch or you could just buy a regular Z-wave switch such as the 2gig/Linear WD500Z along with an accessory switch, such as the 2gig/Linear WT00Z. If you're wiring one of these into a 2-gang box, then chances are you have line in that box so it should work just fine. Another thing to keep in mind if you're going to use one of these is to ensure that the Line and Load that you're going to use are on the same breaker. If they are on different breakers, you are going to run into issues and get some weird activity. You could easily find yourself in this situation if you're borrowing Line from another switch in the box. If you're going to do that, make sure they are on the same breaker/circuit. As far as performance goes, these work very well. It was small enough that I didn’t have any major issues pushing it into the back of the box. The stranded pigtail wires definitely helped with this. I only had 2 issues some people might find a problem with. One is that you'll hear a pretty loud relay click when you're turning the switch on or off. The click is louder than the Aeon Labs/Aeotec micro switch. This is normal since it's basically a relay but it might annoy some people. It's not super loud but you'll hear it. The other issue is that there is a slight delay when flipping the physical light switch. It’s enough to annoy me but my wife doesn’t see it as an issue. Build quality is 4 out of 5. It could stand to be a little bit smaller since the double-switch version is about the same size. The fact that it comes with pigtail wires help tremendously with installation since you don’t have to worry about your connections popping loose when you’re shoving it into the back of your box. Compared to the Aeotec/Aeon Labs micro switch, I prefer this one. The Aeon Labs switch is larger and the terminals are flaky. If you can deal with a slight delay when flipping your switch, then this is the way to go. If you're new to Home Automation, Micro-switches or Z-wave switches, take a look at my Majestechs Home Automation Guide on Youtube. It's a 3-part series with a lot of good information. PROS: Works well if you want to keep your original light switches in place. Small size makes installation simpler Can be wired in a 3-way setup. Just requires some research and critical thinking. CONS: Slight delay when operating physical wall switch Nearly the same size as the double-switch version. (not really a con) Doesn’t provide energy usage.

I was so hyped for these and they install as expected in any existing switch box. They turn any standard switch in a 3-way switch with smartthings being the other "switch"...so the functionality is very powerful...you keep your existing physical switch and anyone can use the switch as normal, controlling the light or fan or heater or whatever is wired to that switch without any difference but in addition you have the power of smartthings....so timer based functionality, event driven functionality, geofencing functionality, and all other automations, plus remote control from anywhere...oh yeah this is a great concept!!!! BUT IT DOESN'T WORK!!! I bought and wasted my time installing 5 of these around my home...exhaust fans, lights, fireplace, etc but they are so frustrating! Works flawlessly through smartthings, whether its using the app to turn on/off or using programmed automations but the physical switch....the physical switch you flick it up and hear a click but the wired device doesn't come on, you flick it back down...."click" and it doesn't come on, flick again and again and it will finally come on....maybe 2 clicks, maybe 3 or 4.....rrrrrgh! Then one day you walk up and flip the switch and it works 1st time?! Mostly 2-3 switch flips up and down before the light or other devices come on...but looking at smartthings the devices are all connected and happy and if I use the app to operate the switch it works everytime the 1st time. So its very frustrating! I feel like the physical switch should just work everytime regardless of anything else...connection, hub status, smartthings app commands, etc....if the physical switch is switched it should work....period!

Best smart switch solution I've found so far. I'm a huge fan on having a regular toggle switch that non-smart home people understand how to use. Just going to comment on some of the things I've seen other reviews mention as issues. Works perfectly with wink, very fast, easy to pair as a generic zwave switch. I followed the instructions which recommended to do an exclusion first, then add the switch. Almost no delay when using the physical toggle switch. The click of the relay is very quiet. It does update wink to the status of the switch, though not instantaneously, takes about 10 seconds. Overall I'm super happy with this product. Will plan on buying a few more in other areas where dimming isn't needed. Hopefully this product lasts a long time. If it fails soon, I'll update this review.

Review of: Single Relay Z-Wave Switch. (Note the reviews on Amazon combined and include BOTH the single and double relay). Quality and reliability are definitely a concern. I have about 10 of these switches now in my home and almost half the ones I originally purchased had to be returned as the z-wave wireless either would not work or wouldn't connect at all to my SmartThings HUB. And most recently, the first switch I purchased and had operating for about 2 months now, had the wireless z-wave connectivity just stop working and wouldn't reconnect to my HUB, although the manual operation still worked when I manually operated the light switch (strange). So I really wanted to love these switches, and when they work, they work great. And some of the switches connected right to the SmartThings HUB with no trouble at all. Other of these switches were a bit more finicky to connect, and as mentioned above, a high number were defective and wouldn't connect at all. But for the time being, the switches installed are all operating and working great. Only time will tell if any other of these switches have a shorter than expected operating life. And if you decide to get the switch, be prepared for a few hours of frustration if you unfortunately get defective ones, like I did. But the alternatives for hardwired in-line hidden switches are few and far between so these will have to do for now. Or hopefully Enerwave takes note and starts producing a more reliable and quality switch.

I purchased this Z-Wave Relay Switch almost 2 years ago with the intention to use it in a ceiling fan, which did not have the fan wires routed to the switch. I never got around to installing it for that purpose. However, I wanted to control the light in my shed located in my backyard. I tried several plug-in type switches however, my dad simply could not figure out how to press a button in order to turn off the light when he exited the shed. I would wake up in the night and see the light still on. I then realized that this relay switch could be used along with a mechanical switch me to use it as a z-wave switch as well as using the mechanical switch to turn the lights on and off, without removing my ability to use the z-wave feature. This relay is very small and fit, albeit a snug in between the switch and outlet in a 2 gang box. It wires in easily and worked immediately. Now to get my dad to understand that regardless of the toggle switch position (up/down) and the light on, simply toggling the opposite direction will turn the light off :-P.
