Very similar to me. The bedwetting scared me when I was really little. Or maybe it was parental disapproval that scared me. Anyway, we went the diaper route. Came to like it and didn’t want to be out of diapers. So then, I was scared I might stop and lose my diapers. So, when brushing my teeth before bed I’d guzzle a bunch of water. By the time I was about nine or ten, the diaper love got strong, so I had more reason to have a need for diapers. And here I am today. Never been married and happily live alone. So all is cool.

Sure is a creative bunch here. The Smart Diaper unit appears to use both temperature and humidity in combination to detect a wetting event. My guess is it triggers not based on a specific level of humidity or temperature, but on the amount of increase from whatever it measures when you reset it and put it in place. I’ve seen it trigger around 85 for both measures, and other times wait until they are above 90. You can set the sensitivity in the app, but it’s just a slider with no numbers. With the Govee unit, you set the upper limits in the app when you want it to go off. Carry on.

Wow, now that’s a project! As far as the detector, there are wifi or bluetooth water detectors that used to send an alert if there’s water on the floor, or wherever you put it. Amazon has one where the transmitter is separated from the little sensor by about 36” of wire. So you would not have to put the whole thing in your diaper. Not sure how that would interface with what you’re building. Anyway, good luck!

Well, I think you just put the last piece in place. Send the output of the phone or tablet to powered external speakers, put a timer on the power cord set to turn them on when you want to be notified if still dry, and set the Govee to sound if temperature or humidity are below 85, and you’ve got the “bedwetting sensor inverted” the OP was looking for. It’s not as elegant as a custom programmed app, but it should work. if you haven’t wet, the alarm will be sounding, but you won’t hear it until the speakers get power. If you have wet, the alarm will stop sounding, and when the speakers come on there will be no sound. Thanks for the help!

Back to the problem this thread was originally supposed to solve — sound an alarm if still dry after a specified amount of time, or at a specified time. The Govee allows you to set upper and lower alarm levels for temperature and humidity. So, you could set the high alerts so high they will never be triggered, say 100 deg F for temperature and 100% for humidity. Then set the low alerts so they are constantly triggered until your diaper gets wet. From experience, try setting both temperature and humidity for the low alert at 85. If you’re dry, you’ll be below those and the alert will be triggered. If you have wet your diaper, you’ll go above, and presumably the alerts will turn off. I believe you can configure the Govee app to send an email when triggered if you register the thing on line and set up an account. It does throw banners up on the screen and play a sound if you have those turned on. The last puzzle piece to make this work is disabling those audible alerts on your computer until the time you want to be alerted if you are still dry. Well, it’s an idea, anyway. Peculiar problems sometimes require peculiar solutions —- from peculiar people.

That could be. I picked the Pampers because the Smart Diaper sensor is supposed to be attached to the outside of a disposable. Placing it against my skin inside the cloth diaper does mean it gets wet fast and stays wet. Maybe a cloth wrap around the sensor would let the wetness disburse making detection of subsequent wettings possible? Worth a try!

Here’s the short answer: Both the Smart Diaper sensor and app, and the Govee temperature/humidity detector work great for recording the time of the first diaper wetting of the night. They work better than I expected for subsequent wettings. So much so, that I’ve got a pretty good idea of when I wet in my sleep the past two nights. To recall, I affixed the Smart Diaper sensor to the back of a Pampers 7 and put it down the front of my cloth diaper, sort of cupping myself like a jock strap. The Govee sensor was put in the lower front of the plastic pants against the heavy overnight diaper briefs. Here are two graphics. The clock is the Smart Diaper app. Red lines signify a wetting, and the blue line shows when I hit the button to reset it after a diaper change. It shows about 11:30 am today, but I actually was up before that and got changed — 11:30 is just went i remembered to hit the “diaper changed” button. It shows two wettings. The graph is the time the Govee sensor picked up a wetting — I think — that the Smart Diaper didn’t. It looks like the 5:45 am wetting took longer to register which figures since the diaper was already wet. The Smart Diaper app missed that one, assuming it actually happened. Something happened to cause a rise in temperature and humidity. In fact, the Govee graph shown is very similar to the ones I got when awake and testing the thing. It’s similar to the two Govee graphs of the two events the Smart Diaper app picked up. So, there you have it. My guess is I wet in my sleep three times last night. The results show two times the previous night. It does explain why I’ve gone to bed heavily diapered forever. I’ll gladly answer any questions, and hope this has been of interest to some of you. I sure has been to me!

Wow, it’s cool to see the interest. Here’s some further information and observations. Cloth diapering can get really thick — at least it needs to with me to avoid saturating the diapers and me. That works against the sensor since it takes longer for temperature and even humidity increases to reach it and trigger it. However, I found a work-around that works great. Just take a Pampers, attach the sensor to the outside like you’re supposed to, fold it back and around to cover the back of the sensor tabs, and shove it in the front of your cloth diaper right next to your skin — with a guy, it would sort of cradle your, well you know what I’m talking about. It gets the works immediately when you wet and the alarm gets triggered in a couple of minutes, depending on how sensitive you’ve set the app. And there as been no problem with the sensor getting too wet. If I’m awake, which I have been while testing this, I can watch the temperature and humidity go up as soon as the Pampers gets wet. Kind of exciting. I don’t know how much weight is given to each measure in triggering the thing. Mine went off with both just shy of 90 degrees and 90%. Again, you can adjust the slider in the app to change the trigger point. When I’m awake, I’ve kept the sound on. When I diaper up more heavily and get ready to go to sleep, I turn the sound off. So after I’ve been asleep and wake up in the morning, I can look at the app and see when I have wet myself. I don’t have a solution yet to the number of times per night. It might be that while the Pampers will stay just as wet after the first wetting, it is likely that the temperature will drop as the diaper cools down. Another wetting would send the temperature up. Would that trigger the app? Working on that. I do have a Govee temperature/humidity wireless sensor designed to be used outside. It’s about one inch square by 1/2 inch thick. Unlike the diaper sensors which only record events and times, the Govee app records data continuously and produces graphs of temperature and humidity. Maybe it would show a bump up in the temperature followed by a fall after each wetting? I could test that by wearing a thicker diaper while awake, dropping the thing inside the plastic pants and outside the cloth diaper brief, and wearing it through two wettings while sitting and reading or fiddling around on the computer so as not to disturb the test with movement. I do have two of the diaper alarms that both connect to the same app, so I can try placing the second one somewhere that doesn’t normally get wet with just one wetting. With plastic pants, I’d imagine the humidity stays constant throughout as it’s all contained, so that might not work. Worth a try. Anyway, I realize that this started out with the goal of creating an alarm that goes off after a specific amount of time if you are still dry. I’ve done nothing to help with that, unfortunately, and have largely taken the ball and run in a different direction — the quest to know how many times per night I wet myself. If that interests you, I’ll have more. If not, well, just ignore my posts! For some crazy reason, this is a lot of fun. There’s a good idea! I will say that the diaper sensor/Pampers combination is pressed close to the skin. So, even dry, it registers about 87 degrees with humidity around 65%. Within a couple minutes of getting wet, both are slightly above 90 with the alarm triggered. However, the Govee when placed outside the cloth diaper and touching the plastic pants starts out much cooler and warms up when the diaper gets wet. So — its temperature may fluctuate up then down after each wetting enough to indicate a second wetting has occurred. Something else to test. By the way, if somebody figures out how to create the original project — the “reverse” wetting detector — I hope something I’m doing helps.

Here’s the update — so far. First, a clarification on “soiled.” The thing is made in Taiwan, and this is a translation issue. By a “soiling event” it means wetting the diaper. It works. I’ve been wearing a Rearz cloth training pant diaper with plastic pants over it to try it out in the evening — like now. I placed the sensor in the lower front with the opening facing the cloth and the back against the inside of the plastic pants. When the diaper gets wet, it triggers the app. If you have sound/vibrate on, you get that. If not, the thing just logs the event and displays “Craig has a wet diaper!” After you change your diaper, you enter that in the app and it resets, logging how long it took for you to get changed and reset the thing. It keeps all this data I think for a month. Overnight, I wore a Babykins pullon over a Rearz training pant with plastic pants over that. Put the sensor between the two instead of next to the plastic pants to be sure it would register. It did, at about 2:45 am. It’s now in the app’s log. Since the alarm is set to silent, I didn’t get changed for another six hours. What I do not know is whether I wet more than one time, something I’m eager to find out. You’re not supposed to get the sensor wet. However, I’ve had no problems. My guess is that as long as you change before you are so drenched that pee is leaking out, you’re fine. I sleep on my back or side, so with the thing in the front, I don’t see a problem. The opening for the sensor is maybe 1/16”. It comes apart to install the battery, so you could blow any moisture out. If you’re going to use it with a breathable/cloth-like disposable, you’d put in on the outside with the sensor opening facing the diaper and would be using it as designed. For disposables, I go with non-breathable plastic, but only during the day when I wouldn’t be using the thing anyway. I’ve realized that if you have plastic pants on, the humidity slowly rises inside. Temperature and humidity are triggers for this thing. Happily, there is a slider on the app that lets you determine at what point you want the thing to trigger. It’s just a slider without numbers, so you have to play with it. I have mine set high now — meaning it takes a large change in temp/humidity from when you first put it on for it to trigger. When I had it set to trigger much sooner, I got false alarms. Again, you just have to fiddle with it I guess. Nothing’s perfect. Also, again, if you are using it as designed — attached to the outside of a breathable disposable — I doubt the “creeping humidity” would be an issue. I did get carried away and bought two of the things. The app lets you connect to up to six I believe. I think what I’m going to do overnight is place one where I have been — in between the training pant and the Babykins pull on — and place the other somewhere that rarely gets wet. Since it detects humidity and temperature, and not wetness directly, I’m not sure how that will be work. It is fun experimenting. Now if you want to go further, there are temperature/humidity detectors that are water resistant and designed to be used outdoors and connect to your device by Bluetooth. They are about half the price of what I’m testing and seem small enough to be comfortably placed inside a disposable or inside your plastic pants with cloth. The things record those two variables continuously for review. Could you use that and review the results overnight for multiple sudden jumps in temperature/humidity? Just a (crazy) thought. I’ll keep fiddling with these, and report back after a few nights of experimenting. Happy to answer any questions. I realize the original idea of this thread is to get notified if you are still dry after a specified amount of time. I also realize I have not helped that cause. However, maybe one of the outdoor temp/humidity detectors (plenty on Amazon) could be used with the app hacked to do just that? I’ll leave that discussion and project to someone else! Have fun! Sounds similar to me. We went through a lot of unsuccessful attempts off an on over a few years. Then I hit that familiar point when diapers became fun and exciting, so I worked against any training so I could still get diapers. You know, when you brush your teeth before bed, sometimes you accidentally drink a whole glass of water…. So I’m not sure if I would have eventually stopped or not. I was still wetting the bed at least couple of times per week when I was around 10 I guess, and the diaper love hit along with my sabotaging of any efforts to get me to stop. Crazy life, huh?

Got one of the bedwetting alarms mentioned above. First, it’s designed for use on outside of a disposable diaper, not where it will come in contact with liquids. I’m going to put it inside my plastic pants and over my cloth pull-on and see what happens. The app is very comprehensive in the data it records — temperature and humidity. I’m guessing it works best with a breathable disposable if it measures humidity? There’s an adjustment for how sensitive you want it to be before the alarm goes off. I have that silenced, so I’m just recording data — I think. The app shows alerts for wetting and soiling as separate events, however I have no idea how it would detect the latter — and I don’t think I want to know. Clearly if you wanted it to go off if you are still dry after a certain amount of time or at a specific time, you’d have to get into the app and reprogram it, assuming that’s even possible. Not a goal of mine. I’m interested in how often and when I wet in my sleep. This may do it of I don’t wreck it from getting the sensor wet. The app will connect with up to six of these Bluetooth transmitters — for what that info is worth. Will report back in a couple of days.

Here’s a different thought. It’s not real clear from the website that this thing records each time a diaper gets wetter, just records the time when it gets wet at whatever level you set the app? Hopefully I’m wrong. However, you could get two of them, connect each one to a different app on a different device and set them to different trigger levels and/or place them in different places in the diaper? Then you’d capture two different wetness levels for sure. Anyway, I’ll volunteer to buy one and test it out!

Do I understand that every time you wet, this thing somehow detects that and records it? I get where it could detect when a diaper got wet, but can it detect when it gets wetter? With disposable and cloth? I’d be interested in it as it is if it recorded whenever I wet myself in my sleep. Would be interesting to know when and how many times per night. As far as “reversing” one of those alarms that just detects wetness and sounds a buzzer, wouldn’t you just need a component that intercepts the signal to the buzzer and sounds it only when dry? Then put a timer on the thing so it only turns on and buzzes only at the time you want to know if you are still dry?

Very true for me.

Thanks a whole bunch! Great stuff!

“Now you are probably still interested in how I have already almost reached OAB - I have already described this in my own blog here” I don’t see a link to your blog you mention about developing OAB. Where would I find it? Sounds very interesting. Thanks!
