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.

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 was a bit worried about this device to control my garage door opener for our detached garage. So far, it's been working great, and I have it integrated into Hubitat with no issues. Its official temperature range is between 32 and 104 degrees F, but it's been doing its job even during the several-day stretch where we were constantly below 0 degrees F.

Purchases this device to control my gas fireplace through Home Assistant. Great product, good documentation, and had to issue at all wiring and adding to Home Assistant. I am very happy with Zooz zwave products.

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.

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.

I'm using this to add remote control to a couple zones of my sprinkler system - I basically run the 24VAC lead from my irrigation controller to a couple relays on the Multirelay, then route those switched lines back and tie them to the zone output terminals on the irrigation controller. This way the controller still works for basic scheduling, and the Multirelay can independently turn on zones. If you do this I recommend adding logic to your home automation system somehow to prevent the Multirelay from activating more than one zone at a time, otherwise you could end up with insufficient water pressure due to running to many sprinklers at the same time.I am using the Universal Devices' ISY994i automation controller with this. When I first tried linking it up, the Multirelay only showed up as a single relay. It turns out this is because my ISY's firmware was too old. It was running 4.7.5; I subsequently upgraded to 5.0.16C (RC1) and re-linked it and everything shows up fine now.General notes and warnings:While you can independently control each relay separately, there is also a control that turns on and off all three relays at the same time - be careful with that one as it could have unintended consequences in your automation system. On the other hand, this is useful as an 'all-off' feature.There are three contact inputs as well; from the Amazon description I assumed that these would show up over Z-wave and that they could be used as general inputs for other automation tasks; this is NOT the case. These are tied to the three relays and are strictly used for local hardwired control of the relays.The unit has a lot of other 'under the hood' settings if your automation controller is capable of writing data to it. For instance, determining how the inputs control the outputs (i.e. latched, momentary...), whether the unit will remember it's relay conditions after a power cycle or not, setting timers to turn off the relays on their own, etc. Details are in the user manual available on the zooz website.I wish the relays were actual z-wave inputs, but it's not a deal-killer, and for the price this is a great little unit.

This is a fantastic little relay with endless uses in home automation. I now have two of these in my mostly z-wave home automation setup. I am using these with home assistant running in a docker container on a server with the zooz z-wave stick.The first one is installed in an electrical box outside. It is powered by a low voltage lighting transformer (12v) and is controlling two low voltage outdoor lighting circuits and one 120v string light circuit. It connected instantly and has been switching my outdoor lighting with no issues. It has seen -25 already.The second I just purchased and installed with the thermostat in my garage. It is powered off of the transformer in the furnace (3 wire circuit from furnace gas valve) and together with a thermostat program in home assistant and a temperature multi sensor on the wall, I can now ask Alexa or Siri to warm up the garage for me. The multi (motion) sensor also automates the garage lighting. I plan to run the garage door opener power through another relay switch to be able to disconnect the garage door power remotely. I don’t have a plan for the third relay switch yet but it could control lighting or an electrical outlet.Having 3 relay switches in each device really expands the opportunities and can reduce the costs. All my zooz products have connected instantly and performed flawlessly. The z-wave protocol is more expensive but is rock solid for me unlike some of my Wi-Fi devices. Taking the time to plan can help expand the uses of multi devices and cut down costs.Hope this helps some with purchase decisions.

Had been looking for a good z-wave enabled relay controller for a while to enable some basic on/off switching automation for various sorts of loads. This was exactly what I was looking for. Setup with my primary z-wave controller was a breeze, and the device works flawlessly. All you need is a power supply (via USB or a standalone wall adapter that meets the input DC specs). Great unit!

Great as a garage door openerInstalled this relay as a garage door opener and added to my Smartthings z-wave network. Manufacturer provides excellent step-by-step instructions. Used it with a z-wave tilt sensor, everything works perfectly. Google Home App recognizes it as a switch, so created a routine for Google Assistant for voice commands: "OK Google, open/close the garage door" will essentialy open/close the door without asking for a passcode.

This was easy to install if you're comfortable with some basic wiring and knowledge. I was able to configure it to use a momentary switch which is nice. It works well within Hubitat and now it runs for xx minutes before turning itself off which was my main goal (30 mins is plenty to warm up the family room) . Next up I will add a blower now that I can tie that in as well (and why I chose this over single relay choices).
