by Ezlo Water Sensor - Monitors Your Whole Home for Leaks - Detects Water Leaks in a Kitchen, Bathroom, Basement or Laundry Room - Zigbee

Edit 11/13/18The first one I bought walked off. I think my nephew picked it up and placed it somewhere. Oh well. It wasn't working at the time because it loves to disconnect from the Wink 2 hub whenever it feels like it. So I bought another and had trouble pairing it (about an hour). Finally it paired and now this water sensor disconnects at random. No reason. I put a new battery in it for good measure. It ran for a few days the disconnected again. I'm going to scrap this sensor and try another brand. Good luck.I used this sensor in my basement by the main drain for the HVAC, water conditioning, water softener, water heater area. If anything in that room starts to leak it will go to the main drain in that area. I placed it nearby the drain. We have a well and it has a Goulds Aquavar pump controller. The pump controller has a jumper wire for enabling the pump to run. If the jumper wire is not there, the pump does not run.So I paired this leak sensor with the Wink 2 hub (easy). Then I paired a z-wave relay switch with the Wink 2. Then I created a robot in the Wink 2 so that if this water sensor detects water it will then tell the relay to break contact. Breaking contact in the relay then shuts down the well controller and, in turn, the well. The robot also sends me a notification that the well has been shut down.The setup works flawlessly. I have had no problems with the Centralite Water sensor at all. It's also nice because it tells you the temperature. It would be easy to setup another Wink 2 robot to shut down the well pump if the temperature dropped to a certain degree. I have another robot for my Honeywell thermostat that does this, so I didn't do it with this sensor.I plan on purchasing more for other possible wet locations upstairs by the kitchen sink/dishwasher area and by the washer and dryer area. It's easy to justify the cost of these sensors and a Wink 2 hub when you figure out what the repairs would cost from a water leak going undetected for hours or days on end.

UPDATE: Just bought a 2nd contact sensor to use it like a temperature sensor. Connected easily and works reliably from 1 room away (no hub, just zigbee connection to my Echo Plus). It can be used in an Alexa routine to trigger other smart devices if the temperature reaches XX. Very happy with it so far. Definitely recommend this sensor over others I found on Amazon. The 1st one is still working perfectly too. Not a battery hog at all. Overall pretty happy with their reliability.I have an Echo Plus (with the built-in zigbee hub). This door sensor works with it right out of the box as advertised. No extra hub required. Easy to connect using the Alexa app on iPhone. I can set up Alexa routines to notify/track when the sensor is opened/closed. I can use the temperature sensor to trigger similar Alexa routines (but I don't really use the temp for anything). Overall, very happy after ~1 month of use. Mine is mounted ~25-30 feet away from the Echo Plus inside the garage. There are 2 walls in between. Connection is perfect. I've tried it 50-55 feet away too with no signal issues. No comment on battery life yet.

It worked very well for 2 years +. Then the LED pilot light started flashing 5 times when it saw someone. Shortly after that I started having issues with it. I looked for a good tech manual but found none. I changed the battery and that fixed it. Note that i used the Zigbee radio. I gave it 4 stars because of the lack of a tech manual.

I have tried 2 of these. Connected with SmartThings. The Temperature sensor seems to work ok, but the Humidity was stuck at 53% on one and 56% on the other one.Since I bought this to control a Bathroom fan, it is useless for me. Might be the cheapest option but since it doesn't work it costs too much.On its way back!

It's a nice device, but to be honest it literally CONSUMES the 3 volt lithium batteries. As in it lasts for a few months, then drops off and when I look at the battery levels I see it start at 100% then after a month it drops to 60% then a bit lower, then bounces around, then drops off line.The device is in the same room as a Third Reality Zigbee plug so it's not a distance/energy issue. I'd recommend going with the TZ3000 series devices as they seem to go for a long time on a pair of aaa batteries with no issues.So yeah, not recommended. I see a lot of people complaining that they drop offline, I'd bet if they checked the voltage on the battery they would see <1 volt (as I did on mine).Oh well.

I bought this sensor to work on our front porch. The package came with two sticky slips for installation. That will work for indoor where the installation location is smooth, but didn't work for our case. I had to get a small flat wood piece, install the wood piece and stick the sensor on the wood. Minor problem.The problem is the following strange behavior. The sensor showed 20% battery after installation. Then after a week, it showed 1%, and then flipped between 20% and 1% every day. It also reported temperature far off. After ten days, it stayed at 1% reporting, and then stopped working.I thought that I received a dude, and tried to exchange it. The replacement sensor behaviors the same. It started 67% battery reporting, then reports 33%, 1%. In the past several days, it reports battery between 1% and 33%. Again the temperature reporting is 5% off (I have another sensor installed near by).The sensor itself works. But I am not sure what to do with the battery issue. If the battery is bad, then I can buy a new battery. But It is not a battery issue.Update (1/28/2019): I raised my rating from 1 star to 3 star for the following reason. First, pairing is easy. It has long range. My Samsung smart hub is about 60 feet away from this sensor. It still works ok. The main thing, as I complained is battery. I am on my second one, which is a replacement. The reported battery of the sensor bounced discretely among 67%, 33%, and 1%. It has been on 33% for three days. The behavior is very similar to the first one which I returned. Is it battery issue, or just reporting incorrect battery level? The product description says 2-year battery life.

Been using it for nine months with SmartThings V2 then V3 hubs. Been working perfectly, and seems to have a very long battery life. Use it for humidity detection to trigger an HVAC fan. Highly recommend this product.

Follow instructions and should be trouble free install. Do cover all exposed wire if not fixed in place

Unit works good, but Smartthings loaded a driver that just didn't work. D/L a better third party driver, now works as expected, but battery way off.
