Zooz Z-Wave Long Range MultiRelay ZEN16 800LR for Garage Doors, Sprinklers, Gas Fireplace; 3 Dry Contact Relays (15A, 15A, 20A); 12-24 V AC/DC or USB C Power; Signal Repeater; Hub Required

Bought this device to integrate our garage doors and driveway gate into our Z-Wave system. Though there are some side gymnastics required to get around Security 2.0 pushbuttons, the relay itself is sold and well-made. Will be keeping this in mind when my Intermatic Z-Wave pool controller goes bad as the relays are capable of handling multiple loads on three dry relays from 0-240V at 15A/15A/20A.

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 set this up with our gas fireplace. I'm only using one of the three relays, so its capacity is a bit wasted in my situation given there are two other relays to be used. But I only needed one and given the low price, I feel it's well worth it. The only thing I wish is that they included a power supply with it. Just be aware you need a 1A USB-A power adapter, and specifically not one for a tablet or PC. I'm using a simple, phone charger which is working great.

I wanted a low-voltage relay to control 12V lights that are powered by a rechargeable battery that is charged by a solar panel. This works perfectly with my HomeSeer system using Z-Wave. I am using two of the three relay connections with different batteries, panels, lights, and schedules. One thing to note, is that HomeSeer shows the status of Relay-1 (I called it Alpha) as primary on the Devices page and the status of the other two relays is shown by icons in the upper right corner. For example, the yellow icon on the image shows that Relay-2 is on. Clicking anywhere in the Device box allows immediate control of any of the three relays. And, of course, you can configure separate events for each of the three relays.

Great versatile zwave relay box once setup. Reliable. Ordered multiple times, all shipped with the latest 1.4 firmware out of the box.The part which really bugs me is the terminal design. This could be a really great product if the addressed a few things:1. Biggest issue, terminal screws punch directly into the attached load wires instead of compressing the wire between two flat metal plates. This results in the terminal screws easily punching through and severing the attached load wires. You have to compensate with enough of a solder mass on the end of the wire and hope it still doesn't break the wire, which is still does sometimes.2. Another issue is that there are no stops to prevent the terminal screws from falling out when unscrewed. So you can easily lose a small terminal screw during installation. You might as well throw the whole thing away if you lose a screw, it's not like it ships with any replacements, nor can you buy them.3. Minor issue but all the terminal screws should really be the same design. Currently half the screws are philips, and the other half are flathead. Just make them all the same so you only need one tool to work on these.Once last thing, a nice-to-have which I hope they add in the future. A programmable auto-shutoff feature on specific relays when the input 12V drops below a certain voltage. This would be great to have to prevent draining a 12V battery source. This is helpful even without any attached loads to the relays, because the relays themselves consume a couple Watts each when on, and can quickly drain a battery. The Zooz unit itself is very power efficient and uses negligible power when the relays are off.
