Water Leak Sensor that Doesn’t Need ST Hub?

Looking for Water Leak Sensor(s) that will work with the new Smartthings (no Hub). The Govee gets great reviews and inexpensive, but, not sure will work with ST…only their own app.

Unfortunately there aren’t very many choices that will work without a hub. What country are you in? That will make a difference.

If you find a model that works with IFTTT, you might be able to get partial integration that way.

For example, dLink makes one:

Home Depot also sells the Bazz brand which also works with IFTTT.

If you want something fancier (and more expensive) the “notion“ system seems to be well engineered and has a good IFTTT channel. You have to use them with their own bridge, but you don’t need a smartthings hub. Integration is through IFTTT. Their sensors are multi function, and can be used for leak detection, motion detection, a couple of other things. The cost is high, $149 for the bridge and three sensors, but they get good ratings and they do a lot.


My biggest concern with a company like notion is they are essentially in start up mode. Good engineering, lots of cool features, Nice aesthetics. But I don’t know if the company as a whole is financially viable or if they are just hoping to be bought by someone else. So I think there is a little more of a risk that their system might shut down in the future. of course there’s always a risk with any individual model that a company might discontinue it, but with something like this one, if the company goes out of business the devices will just stop working altogether. So just another factor to take into account. :thinking:

To add to what @JDRoberts said - in most cases you WANT water leak sensors to work with a hub.

In a hubless config that means your equipment is controlled by the cloud. That also means for everything to work - you need power, Internet access, connectivity to the cloud(s) involved with device control AND automation. If any of them fail - your alert / automation doesn’t work.

Now, if instead you have a valve and sensors that all work with local capable device handlers (it’s possible) you in theory will very soon be able to setup local automation that basically says - if sensor wet - then close valve. (Yes it’s theoretical, but should be possible with the conditions stated and local automation capabilities coming soon)

Choice is good - but consider that caveat when you’re talking about protecting property and it SIMPLY MUST WORK.

All good points, But in a smartthings-based system all notifications require the cloud even if the devices themselves don’t. Plus the fact that the company can and does push hub updates that can be neither deferred nor denied, and that can take the hub itself off-line for a little while. So “simply must work“ never really applies to a smartthings set up. (Spoken as someone who does rely on some emergency systems which have to have very high reliability.)

SmartThings is about convenience, But with or without a hub you have to accept that reliability is not its strong suit.
