Elephant in the room alert: smart home devices are for hackers.You can spend a ton of money and get some lights to turn some colors and you can be satisfied with that... until a regular human being comes by and flips off a light switch.You can buy from the largest supplier of smart systems - even from the largest supplier of electronics in general - and set up a sensor that turns on a light and you will eventually be stumbling around in the dark.Smart devices are generally can't be used when failure is not an option.I already trusted Zooz when choosing this really, as they make the only line of switches that I know of that work reliably in hardware and software mode (with relay and without relay; for dumb lights and for smart lights). Software switches in my house are necessary in order for literally every single other person who turns lights on and off in my house to live in harmony with me. As an aside from this review... can some people please realize this problem? Do smart device manufacturers not live in smart homes?My hack is somewhat elaborate: first filtering high-solids koi pond water through a filter to a pressure sensing high PSI pump to a set of electronic irrigation valves and finally out of garden sprinklers to water and fertilize my gardens. Though running this type of system through a smart hub has it's advantages - the ability to use weather patterns, soil sensors, and pond water level to decide if watering is needed or possible - it could easily malfunction and drain all the water out of my pond. My fish wouldn't like that. Besides the reliability of this Z wave device - which I did have trouble with at first - there are some failsafes this multi relay provides. Mainly the turn off after x feature. My former hub would lose connection between starting and stopping these relays which would, without this feature, cause my sprinklers to run forever. Also there are enough relays to turn on each of my two sprinkler zones and turn off my pressure-sensing water pump when not sprinkling. If a pipe breaks or a sprinkler clogs, this will keep the pump from running constantly (as this kind of pump runs atomically on a pressure drop on the output).So it works well in my very specific scenario... so what?I have bought two more to play with. Again, smart devices are for hackers, and this box is a hackers dream!. You can pay nearly this much for a single relay, but the Zooz multi relay is full of features that make it more versatile than it needs to be:Each relay has an input for a hardwired switch or button. This is great if you're designing a system that may be used by people unfamiliar with smart systems.There are, again, three independently controllable relays.Zooz's device handler has a huge amount of customization options, also Zooz offers a couple custom applications, at least for Hubitat and Smartthings, that perform common functions. There is, for example, a Zooz application especially for running automatic sprinklers (the controls are a little basic and advanced features can't be used in combination with this application.)Z wave is very fast and reliable on some hubs.My favorite feature: This multirelay can be run on a very wide range of AC AND DC voltages. If you have an AC sprinkler system like I do, your sprinkler transformer can power this unit directly. If you have a low voltage landscape system... AC or DC... you can power this relay with the landscape wire. If you are using this near your doorbell wires and not near an outlet, you can likely power this unit off that.As much as I am gloating about this magical box, it wasn't all roses in the begining. My main issue, which I realized after months of toying with all the Z Wave devices in my house, is that my Smartthing hub's Z wave implementation was very slow and unreliable. After moving everything in my house to Hubitat, everything but this device worked perfectly. This turned out to be an issue with Hubitat's newest hub having a Z Wave software issue. Zooz did note this issue and suggested pairing without authentication as a quick fix, which worked. Hubitat has since fixed this problem, and I couldn't be happier with my setup now.The versatility of being able to meld the various triggers and sensors a smart hub system can connect to to three independent relays ought to trigger some use-case ideas for anyone. I'll be building some halloween props with my spares and some Z Wave PIRs. If only... and by the way why not... they made an waterproof version.

Works great with my Hubitat hub to control my Garage doors. Have another one that controls some outside flood lights for when the dogs are out at night.

I bought one of these to test out on a couple of different applications and ended up immediately buying a second one. I have a gas fireplace (Heatilator) with a low voltage switch on the wall that turns it on and off. I wanted to be able to turn the switch on and off via SmartThings or Alexa. The switch basically just makes contact between two wires, which is what a relay does. All I had to do was cut the two wires going from the switch to the fireplace ignition controller, insert the wires from the switch end into the Sw1 ports, and the wires to the controller into the Relay1 ports, added the device handler, and added it to my SmartThings hub. A quick google search will lead you a couple of guides which were clear for me aside from how to wire it which is as simple as I described above. Now I can control my fireplace via SmartThings/Alexa AND still use the switch as I always have.My second application was to open/close two garage doors. Both are Liftmaster MyQ and I didn't want to use their proprietary hardware which requires a separate app and a monthly paid subscription for Alexa control. Instead, I took a spare remote door opener and soldered two wires each from one leg of the button inside the remote that I opened up. Again, the button just makes contact between the legs so I made it so the relay will do that upon activation. Again, added the multirelay to the hub, made it a momentary switch, and voila. I have a spare garage door opener sitting in the basement that's wired up to the Zooz multirelay with two simple wires for each button. There's also a SmartApp for SmartThings (again, Google is your friend) to have a "garage door" device where you configure the tilt sensor and the switch and it will show in your SmartThings home screen the status (open/closed/opening/closing) and you can press it to open or close.Both applications were way easier than I could have ever imagined, were budget friendly, and were nice and clean solutions - which is exactly what I was looking for. Big props to Zooz for a great, reliable, and universal ZWave device for us tinkerers!Future plans are to add the blower switch in the fireplace to one of the other two relay slots (since there are 3 per unit!)

I have quite a lot of Z-wave devices and wanted to add a garage door. I bought the z-wave/garage door device that popped up on Amazon, and that was an unmitigated disaster. So instead, I was redirected to this one which is not really a dedicated garage door opener but a relay that can work as one. It pairs very easily with SmartThings (after installing the required driver, which is easy), and the settings can be adjusted so that it works pretty much as a garage door opener. The wiring will depend on how your actual motor works, and in that respect Nikke and Sara at customer service have been fantastic guiding me. The app won't tell you whether the garage door is open or closed, so use a camera or a door sensor, but it works to activate the door. I've only had it a few days so I don't know how stable it is over the long run, but it definitely works well so far. And there are no words that would praise customer service enough.

I was looking for a solution to automating my garage doors with out using WiFi. I originally used some Sonoff wifi switches but it was too much work for what I wanted to do with my smart hub. I found this and I loved the fact that it was 3 switches in one unit. Outside of losing the device handler for smartthings, installation was easy. With the device handler you change change reach switch to "garage door" mode. (Momentary switch is also available).I chose to connect the unit at my wall switches, just because it was easier for me. If I need to tweak something I didn't want to go up on a ladder. A USB cable was included. I used an old phone charger to power without any issues.From there I set u a room called garage and a cooler of automations using the root sensors I already had on the door. For example at 8 o'clock at night if a door is open it will automatically close. I also have some echo routines to announce when you're door is open or closed.I would recommend for those that are into automation and want an easy solution.

Did exactly what I was wanting to do with it. Controlling two separate garage doors with smartthings. The install was very easy for me but I needed help with the device handler. I emailed back and forth with tech support . Karen had the patience of Jobe and had me up and going pretty quickly. The unit comes with 3 outputs which was perfect for me, two for the garage doors and I had already planned on putting in an exhaust fan in the garage later on during a remodel someday, so that worked out good. Wiring to the chamberlain was just as it should be but the lift master is a myQ and uses a proprietary switch so instead of wiring to the back of the opener like the install diagram shows I had to run all the way back to the myQ switch in the wall and solder it in parallel to the contacts. The only minus I have with the whole thing was in the app there are three outputs but four switches. One for each output and a parent switch, the parent switch toggles all outputs at the same time which in my case isn't needed unless I wanted to open both doors and cut on an exhaust fan with one button push. It's not really a minus its just I haven't figured out how to make that switch go away and my smartthings app is pretty congested . All and all I'm very happy with this thing and plan on another one or two when I start my gate project some day

I'm using the ZEN16 to control a whole-house water shutoff that formerly was controlled by an Insteon setup. The valve has NO/NC wires, with one turning off the valve and the other turning it on. So. I needed a relay that had NO/NC contacts. The first one I tried (another brand) was DOA, as was its replacement. I then ordered the ZEN16, and at first was concerned that it didn't seem to have NO/NC pairs, but I found that relays 1 and 2 could be configured that way so that if you turned on one, the other would turn off. Works perfectly. I also appreciate being able to program it to revert to the last setting on power fail/restore.There is a small blue LED whose operation is also programmable. By default it indicates the state of the relays, but I set it to be always on when power is supplied. I am not using the switch inputs.Perhaps my only gripe regards the USB-C port for supplying power. This is what I call "fake USB-C" and it won't accept being fed from a real USB-C power supply. Instead, you must use a USB-A to USB-C cable (one is included) and your own USB-A supply. I don't know why companies do this - my understanding is that a simple resistor would allow it to work with a USB-C charger.

I had mimolites in my fireplaces that all started to fail after years of use. I replaced one with this and love it. With this unit you get to keep the full functionality of the wall switch and zwave control. Admittedly, it takes some getting used to. For instance, if you turn on the fireplace via zwave and someone wants to turn it off at the switch they may have to flip the switch up (on) for off. It’s like an old three-way light switch where one switch is up while the other down. Eventually you get used to it. I mainly use Alexa but some others prefer to flip a switch as opposed to talking to the air. Unit works flawlessly and Zooz support is very helpful.
