Frequently asked question

Does this sensor work with the smartthings hub v2 without adt?

Yes. HOWEVER, when you add the device DO NOT try to add an 'ADT Water Leak Detector,' you will get 'Couldn't add device: You need a hub to connect to this device.' INSTEAD, add a 'Water leak sensor: SmartThings.' That works just fine. You're welcome.

Does the sensor require and adt subscription? or monthly fee?

Nope, just a connection to you smart hub.

Can i use this product without any paid services through adt? i have a smartthings hub, but don't want to have to pay for adt home monitoring

I have it connected to my SmartThings hub and it works great with no need for paid services.

Can you hard wire power to it?

Theoretically yes if your good with soldering and modifying electronics

    Pairs just fine with SmartThings Hubv2!

    Pairs just fine with SmartThings Hubv2. Also, this has a very nice design where it will detect water which lands on it’s top or pools around it on the bottom. The long battery life is awesome for making sure our tankless water heater which is installed in the attic isn’t leaking.

    Works perfectly with regular SmartThings hub

    First off, unlike some of the SmartThings/ADT sensors, these DO NOT NEED the ADT hub. They paired immediately and work just fine with the regular SmartThings hub.
    It’s not totally clear from the product photos, but these have 3 small contacts on the bottom side that nearly touch the ground. Whenever water creates a path between 2 of the contacts, the sensor will trip and alert you. Additionally, the top surface is cup shaped, leading to a channel with 2 more contacts that will trip the alarm if more than a few drops of water fall on the top.
    I tested both the top and bottom sensors, and they were pretty sensitive! The bottom sensors would detect the film of water left on a flat plate after rinsing it off, and the top sensor needed less than a teaspoon of water dripped on top to set it off.
    As an added bonus, the sensors also report the temperature, and can be used in any automations that allow a temperature sensor to be used as a trigger!
    I bought two of these when they were on sale for $10, and will definitely buy a few more if they ever go on sale again.

    It works GREAT !!!

    This is important because a few years ago the carpet in my basement office was wet. Searching for the cause, our prior water heater was leaking in the storage room. We have tried other wet-floor devices – BUT – We can not hear the alarm when testing. This wet-floor device sends a signal to our smart phones through the Samsung SmartThings Home Hub. We can add other security devices in the future.

    New design has twice as many features.

    Much better than previous designs, this leak detector proactively monitors for leaks – meaning it will catch the drips and trigger if placed under a leaking water source (i.e. kitchen faucet connections, fridge icemaker connections). Most leak detectors require a puddle to form before being triggered.

    Works with Smartthings V2 Hub

    Bought three of these back in Aug 18. Paired right up with a V2 hub, no problems. Accidentally spilled some H2O2 under the sink in the bathroom and it went off. Works so far! 89% battery after 4 months and one of the furthest devices I have away from the hub with no repeater in between. Not too shabby!

    Great z wave leak detection.

    Great little Leak Detector. I bought one 2 years ago and it has worked perfectly. Battery still hasn’t been changed. I just bought 2 more for other areas of my home.
