Wyze Leak Sensor - First Impression

@revsamarshall The probes are back in stock. I’ll wait to order some so I don’t single handedly deplete the stock… Like what happened to me yesterday trying to buy a pair of the Jordan Mid 1s in light smoke Grey and white :rage:

Kidding (not about the shoes but the probes), I only wanted a few more, but get them while they are there!

I look forward to hearing your findings of your tinkering! If the reverse sensing works well. I think the best option is to tell it to only notify you if it’s been clear for X amount of time in a row…then little waves and splashing won’t send random false alarms that it got low when it really didn’t.

Did you see the Probes are also back in stock now? (EDIT: Ha, nevermind, I just saw you just mentioned this right before I posted) I know you said you wished you had more of them. I love that probes are only $5 each! Not a big deal to lose a probe or 2 for such a good cause, eh? :slight_smile:

My only debate is whether to buy a bunch more of these sensors right now, or wait up to a month or so and see if there are any good discount codes or other things that come out around Black Friday again like last year when I ordered a bunch of stuff in bulk (Last year’s Black Friday actually got me to test Cam Plus for the first time ever, and now I have cam Plus on EVERY camera). I just don’t know if I can wait that long though. Plus it might be easier to place an order now, so when I place an order again around Black Friday it doesn’t look to my wife like I spent as much on my toys all at once. :rofl:

As a side-note, do probes count as a Wyze device in our contest of who has the most Wyze stuff? If so I might have to buy a few extra just to keep up! :rofl:

I did, ordered 3 sets. I think I may take the casing off one to see it’s innards but still would like to monitor my hot tub water level over the winter with it.

I also have a climate sensor and leak sensor in the body of the Hot Tub as well to keep up with temps in the pump and hose space.

I would say the sensors are the smart piece, therefor the extended probe should not count as it is an add on? What do you think? We just need to lay the rules down in our Wyziest home showcase. :wink:

Starting to plan out my Wyze Basement… so be ready… 2k sq ft of unfinished basement. It’s a blank canvas my friend. I just need Wyze to make with the smart switches soon, smart outlets… (not plugs) would be nice as well.

Sweet! If you take it apart take lots of pictures and do a new thread. Maybe a video too.

Yeah, I guess we can have 2 ways of tracking. Will have to update a shared spreadsheet template one of these days when I’ve finally installed everything in my new house.

Just a short update, I finally installed a probe fully submerged in water in my cat’s drinking water fountain. I set the probe to sit just above the little pump/filter. I set a routine of Wyze rules for if it ever goes 5 minutes of being “clear” of a leak (no water connecting the probe contacts for 5 minutes straight), it will run a routine of turning a bunch of color bulbs a certain color so that everyone knows that the water level in the cat water is getting too low. It’s been fully submerged for almost 24 hours now and is working great. I initially had a routine to have a siren go off, but decided I didn’t want that happening while we slept :rofl: so I switched it to turning nearby color bulbs a certain color everyone will recognize the message for.

I’m excited. We had a previous fountain get ruined by going dry and ruining the fountain filter/pump. This leak detector probe will resolve that issue, And because the leak probe cord is so long, I was able to stick the main unit right underneath a group of pipes and drains so it can do double duty and notify me if the main unit senses a leak too.

I was wondering if it would work okay like this, but my tests so far show it’s totally fine and working great like this…the main unit making sure things stay dry, and the probe making sure the pet water area stays wet to a high enough level. I love it! I hated feeling like I had to constantly keep checking up on the pet water to make sure my daughter was filling it up like she agreed to so it doesn’t get ruined and so the pets stay alive! A small weight lifted off my stress load (and wasted time) is priceless.


If you want reliability, I’d still seal the non-IP rated sensor cable entry point with some silicone rubber, like RTV.


Yeah, I plan to do this for other ones I intend to submerge (swimming pool water level, etc), I was just feeling too lazy (and time lacking), and felt risking the cheap $5 probe was worth my laziness and time saving for one test! :rofl: So far, so good…though I would recommend other people follow your advice to seal around where the cord goes into the probe just to be safe (if they plan on it being submerged). Thanks for the reminder so people don’t assume it is IP rated when it is not.


Let him make his own mistakes :rofl:

But you will find this interesting @Newshound and @carverofchoice

ahaha thats awesome. Can I possibly get a video or photo of the setup? Wanna show the team the ingenuity of our community


Of course. Let me run some tests to be absolutely sure how it works after extended submersion (might get water-logged or something for example). Then I will add some media and a good report on how it works.

Currently siding with @Newshound 's suggestion to put sealant around the corded area of the probe.

DISCLAIMER: Again, remember I voluntarily chose to test the probe knowing I might ruin it, so I am not recommending anyone else submerge these devices without accepting the warranty would be void.

As previously stated, I submerged a probe under water to sit just above the cat fountain pump/filter, hoping it will alert me when the water gets low. In my tests of short submersion it worked okay (leak detected, then after a couple of minutes I take it out and the leak cleared). But it needed a longer term submersion to be sure. I left it submerged for a day and a half and tonight I removed it to see if it would clear like it did with the short tests.

When I took the probe out of the kitty water fountain/filter to test if it would still clear after being submerged for a day and a half. It did not clear immediately. Soon I set it on a dry surface and it did not clear. I wiped it dry and it did not clear. I left it there to track how long it would take to clear.

The Probe took 2hrs 10 min to clear.

But it did eventually clear, at least while on a dry surface. (And the notifications and routines DID run, changing a bunch of nearby color bulbs to different colors, prompting my daughter to call out to me asking why her bedroom light suddenly went red :rofl: I hadn’t told her about the rule/routine yet.)

I then moved the probe around to see if an internal pool of water would set it off again to detect a “leak” but it stayed clear.

I then touched the probe to a wet surface (the top of the filter/pump I pulled out of the kitty water and it detected a leak again. I propped one side of the probe off the surface of the pump so it hovered in the dry air, but the leak wouldn’t clear.

Then I put it back to a dry surface and this time it took 1 hour 15 minutes to clear even though it wasn’t submerged the second time. Interesting. If there is an internal water source, it needed an external wet surface to set it off, but once it detected the wet surface it wouldn’t immediately clear again. Will test further, but definitely recommending the next test for me or @R.Good be to try sealing the cord entrance area better before the next long term submersion test and see if that gives an an improvement to allow it to clear in less than 2 hours. :slight_smile:

AGAIN to anyone following these tests, R.Good an I accepted that we may damage our probes in these experiments, that it would be 100% our fault, and they would no longer be under warranty. We just feel figuring this out (if it’s possible) will make for some really beneficial use-cases for ourselves. :slight_smile: Plus it’s fun.

I look forward to the next phase of testing with sealant and see how that works out. Once we figure out some reliable solutions I’ll probably include a video or pictures or something. :slight_smile: Gotta perfect it a little first…though I’m about to be out of town for a minute, so I might have a delay in testing.
