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

excellent water leak sensor which is compatible with Smartthings

Edit 11/13/18 The 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.

Having owned several Centralite products and having been happy with them, I figured I would give the Leak Sensors a try. These are horrible. Terrible battery life. They would pair in Z2M but not expose the Leak Sensor portion, had to reset the device and Z2M container multiples times. Then when battery dies you have to force remove, then go through the same hassle of re-pairing. Save your money and get the Tuya sensors you can pick up two for the price of one these overpriced battery pigs. Those paired and reported perfectly. Oh well back to more Home Assistant fun.

I purchased this product because I wanted something to monitor my sump pump for failures and notify me if my sump pump failed and the water level was rising. I have a water backup sump pump in case my primary sump pump fails, but I wanted something to notify me if the primary failed, so my water bill wouldn't be crazy high. This integrated into my "SmartThings" perfectly and sends alerts soon as it detects water. My internet and SmartThings are on a battery backup system, so if the power does go out I will not that my sump pump isn't working as well. I included some pictures on how I modified this to work for a sump pump. This device on its own works perfect for setting it on the floor or under a sink, but you don't want to submerge it underwater. You will see in the pictures I soldered some wire to the leads and put this section into the sump pump. I zip tied the sensor above the sump pump to some of the drainage piping. I used two splice connectors to the ends going into the water to prevent the wires from somehow accidentally touching and sending a signal. When the water rises and submerges both splice connectors the connection is bridged and the alert is sent.

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.

This is a plug and play sensor that works well with Wink, but when I left Wink for Home Assistant which uses Z-Wave, it does not pair. That is not a fault of theirs, this is just a heads up if you want a Z-Wave compatible sensor, this is not it. I do like the sensor though when using Wink.

Great product at a great price

I use these in conjunction with my Hubitat home automation system. I have purchased these in the past and have been very happy with the results I've gotten with them. Battery life is exceptional, I get about a year on either the lithium batteries or rechargeable batteries. While the rechargeables do cost a bit more up front I hate throwing batteries away. These sensors work flawlessly with either. Not only would I buy these again, but I already have!

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