Ecolink Zwave Plus Flood & Freeze Sensor, White (FLF-ZWAVE5-ECO)

Ecolink is a great z-wave product line. Reliable, easy to install, great compatibility with z-wave hubs, and very long battery life.What I like best is it has a long cord between the sensor and logic unit so you can install the sensor where it is needed to detect flooding and install the logic unit in a convent spot for changing the battery.I'm installing this on my A/C condensation pan in the attic so I'll immediately know when the condensation line is clogged, and if the attic is freezing.Highly recommend this product!

The sensor I had placed underneath my water filtration system triggered a Home Assistant alert late one rainy night. A crack had developed in my foundation and under heavy rain the water started coming in. This sensor detected the water intrusion early enough that we were able to mitigate any water damage in the finished section of our basement.I have a sensor on my water filtration system, hot water tank, sump pump, and furnace (in case of condensate backup). The batteries last a very long time.

These sensors are nice; there's a long cord to connect the sensor itself with the Z-Wave unit, long enough to get both mounted without too much effort. I did find that the tape supplied didn't stick particularly well to many surfaces (no surprise) so it's best to use screws. You can actually mount it to a shelving unit or even a piece of wood that won't float if there's a flood. The setup with the hub is easy; it works better than many Z-Wave devices in fact. Range is good; with one active repeater in the basement the whole area where I installed the leak detectors was covered fine.

After spending nearly the last two years remodeling a 115 year old house, a lot of that time was spent turning it into a smart home. I've replaced all the light fixtures, bulbs, light switches and outlets and built this all around SmartThings. Virtually any light, appliance or IOT device can be controlled with SmartThings and by voice via Google assistant integration. This is a Z-Wave device and is "compatible" with ST, but really needs a custom device handler (DTH) to make it work well. The first time I had to load a custom device handler into ST, it was a little intimidating, but now it's a breeze. I didn't need the freeze alert trigger on this device, so a free device handler I found on github works for me. I can monitor wet/dry and the battery life/status with this DTH. I bought a few of these sensors and put them behind my refrigerator and dishwasher. I just picked up 3 more to put behind my toilets and washing machine. I have some other Samsung and Zooz "puck" water sensors strategically placed under sinks, the water heater and a water softener to really monitor all the places that could potentially have water issues. With the SmartThings app, I've got an automation setup to turn some key led lights in my house on bright red to alert me to a leak issue. With a Dome motorized valve closer, the ST automation will also shut off the main water line to the house until I can determine what is leaking. I also have ST send a text message to my phone, that a leak has occurred. I like these Ecolink sensors for places I can't get to easily, like behind the fridge, dishwasher or washing machine. I use the sensor/probe on the floor, near water source and run the battery pack to a location that is easy to reach, which for me was in the cabinet, under the kitchen sink. That way, in the future, I don't have to pull the appliance out just to change the battery. For the toilets, I placed the battery pack under the tank with some 3M tape and ran the wire down the supply line with zip ties to the floor where I placed the sensor/probe near where the supply line come into the room. I didn't want to use the "puck" style leak sensors under the toilets, as we have cats and I thought they would play with them and get moved/lost too easily. With these Ecolink units I can secure wire to the supply line and the probe to the baseboard on the floor with 3M tape or screws. The sensor uses a CR123A battery which is great (common and inexpensive), as these sensors don't use a lot of power (thanks to Z-Wave) and should last well over a year. I've yet to replace any of the batteries on these sensors.

Updating my review. My initial review was that this was pretty bad device. Turns out this was an Amazon fulfillment issue. Even though the product was marked as new and sold by Amazon.com, I received a very clearly used and broken device. Amazon eventually got around to sending me a replacement so just watch out if the seller you select is Amazon.com.This device works flawlessly with my SmartThings hub. It does show up as a contact sensor in the hub. However, I have my hub connected to Home Assistant and do most of my automation via Home Assistant with the SmartThings really just acting as a relay (via MQTT). Via MQTT, I do see the broadcast of wet or dry. The event notification time is very consistant and never more than a second.

After trying every device type in SmartThings that had anything to do with water/moisture, none of them worked as both a water and temperature sensor. The water sensor worked on a number of device types but none of them worked as a temperature sensor. Hopefully, someone can create a custom device type/handler to make this sensor work as intended. Right now the “Z-wave water sensor” device type works for just water and is a good option for Z-wave environments. The device is very small, well constructed and the CR123A lithium battery coupled with Z-wave plus should give us 5 years of battery life. Good product with the best in class battery life but without temperature in SmartThings environment.Update 12-5-17:RBoy Apps has created a device handler that works with SmartThings. If you are comfortable adding and changing device handlers this solves the only issue that the device had.

I bought this to use with my freezer. I was hoping to use it to alert me if the freezer starts thawing. I wanted to have the probe in the freezer, and the main box on the outside of the freezer. Unfortunately the probe does not have the temperature sensor, the main box (with the battery) does. Having a lithium battery inside my freezer is a deal breaker.Outside of that, this thing was a royal pain to get talking to smartthings.
