Zooz Z-Wave Plus Power Switch ZEN15 for 110V AC Units, Sump Pumps, Humidifiers, and More

Love this plug! To be clear, I only just installed it today. I have a Hubitat hub, which I use with Home Assistant, and it has official support for the Zen 14, so was easy. I started as I always do by “excluding” it, which literally took it less than a second. Then I put the hub in inclusion, and it did in less than 20 seconds. I think it’s the fastest Z-wave pairing I’ve ever done. Then I named the whole plug (Outdoor Plug 2) and saved. Then it shows in Device names as the named whole device, with daughter plugs named long string of gobbelety gook. But you just tap on each one, go into Device Info, name as desired (Deck Lights 2A and Deck Fountain 2B for me) and put any reminder notes you want and Save each one. Voila! Now they show up on my Device button page with real names, and the response to commands is instant, no lag at all, even though plugged in outside under a deck, about 65’ from the Hubitat. The only thing left to do is put the lights in to my Outdoor Lights routine, which may be a little more work doing an “AND” routine, since all my other lights are on dimmers, not switches. So that will take me at least 2-3 minutes 😄

Perfect for an outdoor repeater. My house and detached garage have zwave devices, while the house has the zwave controller. I’ve struggled to reliably get the signal to my detached garage zwave devices until this device. I plugged it into an outdoor outlet on the back patio and now all of the devices on the detached garage work quickly and reliably.

I live in the subarctic. My home water situation is "different" from most places on earth. I have a water tank buried in the ground and a pump that draws water to supply my home. As you might imagine, that pump is absolutely mission critical to my home's operation. Put simply, I wasn't going to trust it with a cheap $10 WiFi plug. The typical draw is approximately 800 watts, with even higher startup peaks.I use Home Assistant for my home automation platform. Using Z-Wave JS, this switch enumerates on/off status with switch control, amp draw, voltage level, watt draw, KwH usage and ping. Most important to me, this unit can be configured to remember "last state" or be "always on" - meaning, it will always return to on state for my application. Also important, this device can be monitored for "alive" and "dead" status, which I can then alert on. In my application, I actually use two methods for this assessment - a UPS battery status over WiFi and this switch - both of which tell me whether the pump has power.Interestingly enough, I wasn't really interested in turning my pump on and off with this device, almost ever. We've burned through a few expensive tanks of water due to leaks and faucets left open, though. I really wanted power draw because it allows some interesting analysis. I can now measure and alert on "abnormal" power usage, which can indicate higher or lesser than normal operations. (Such as "pump running when we aren't home.") Though I haven't actually done this yet in my automation, I can kill power to the home water pump in the event abnormal usage is detected. For now, I'm using alerting & manual switching based on alerting and that's probably good enough for me.For me, the return on investment will be the prevention of just one of those events. It took me a little bit to figure out how to do the analysis in Home Assistant, but I think I figured it out. Essentially, I'm taking power draw for the previous 15 minute increment, determining if that exceeds a "known normal value" and send an emergency level alert to my phone if that event occurs. Sure, it triggers sometimes when we take a long shower or water the garden, but we know about these things and I want it sensitive enough to detect even a slow leak. I also have a secondary alert that tells me if the pump is active at all while we're away, which really shouldn't ever happen.I gave some serious thought about getting into "water monitoring" side as an alternative to my application. When I looked at general cost, managing water is much more expensive than monitoring electricity. It was kind of a "stroke of genius" when I realized that monitoring my pump electrically could get me there just as easily. So, that's a win for this platform in my opinion.So far, this product got me where I wanted to be, has been reliable and seems to handle a serious electrical load without issue. If anything changes, I'll be sure to update this review. While it's on the "more expensive" side of energy monitoring and switching these days, I'm usually willing to pay a bit more for the highly reliable Z-Wave technology and a quality product. I'm thinking about getting a few more to monitor my furnace and a few other important applications, so that's about as good of a recommendation as I can give.Edit: I've used same device in a few more applications now, still love it. I use them on my furnace and fridge, both mission critical applications. (It took some serious trust building to put one on my furnace!) I also use them in my shop. This unit is the only one I've found that deals well with large startup (inrush) current. Things like shop-vac's and my compressor would "pop" other devices I tried, but not this one!

FIVE STAR

Bought this device so I could monitor and bill a tenant for their portable air conditioner since they apparently need to be refrigerated at a temperature well below where I set my HVAC thermostats.Initially the device seemed to be working just fine but it would randomly shut off power without being manually switched off or commanded to switch off via my Home Assistant Hub. Other than that, it appeared to function as expected and the values being reported were inline with expectations.Because of the random shut offs I searched for and found a newer version of the firmware for this 2nd Generation Zen 15 device. Firmware version 2.10. Unfortunately, after updating the firmware the device is now reporting wildly inaccurate kWh consumption.For instance, before the update to the firmware a 49 hour period of use resulted in 41.557 kWh of consumption which seemed appropriate for a device rated at 1150 Watts.Following the firmware upgrade a 23.75 hour period had this device reporting 135.722 kWh of consumption which is simply impossible because a 1150 Watt device, if it ran for 24 hours solid, would have consumed only 28.8 kWh of consumption and an air conditioner does not run solidly over time as it has periods of standby (which reports ~54.5 watts of usage when in standby mode).This issue renders this device useless for my purposes though you may need it for something else and don't care about the cumulative power consumption.
