Moen 920-004 Flo by Moen Smart Water Detector, 1-Pack

App (Flo By Moen) not available in UK on IOS or Android to operate the device. This is a shame because the device looked to be well made. At least the seller gave a full refund.

Received the product only to find the iOS application is not available in the UK rendering the product a pile of useless plastic and metal. Without the app you cannot creat and account to monitor the devices. Strongly suggest if UK based and on IOS you find another solution that will work. This will not and pointless. Now wasting my time to return the item. Adding it took 10 days to arrive.

The setup was easy and it's showing me room humidity, room temperature and no leaks.

I purchased 4 of these devices: The first 2 paired without issue and appear to be working fine. The battery on the first one died within a few days, and the 2nd one lasted about 2 weeks before dying. These use CRA123 batteries which do not come cheap. I was never able to pair the 3rd one, no matter what I tried; it always failed once I connected to the wifi network. I tried adding the network manually, I tried resetting the router, I tried changing the AP name, I tried manually connecting to the network, every single attempt failed, and customer service is of absolutely no use. The 4th one paired, and despite having a brand new battery (not the one provided) it reported the battery at 43%. I took out the battery, and the app never informed me that the device was offline, I even waited 20 minutes to see, and still nothing, it was reporting the same 43% battery level and offline. Bottom line: I would not trust these things to alert me in case of a water leak. Given the cost of each device, I would have expected it work flawlessly, but I'll be returning them and going with either Honeywell or pretty much any other brand. If your devices all appear to be working, I highly recommend doing a test to see if they are reporting correctly, dip the sensor in water, try taking out the battery, and see if the app reports it.

Doesn’t work, I tried to returned but need to send to USA and costs a lot. Not compatible with app

No instructions re setting up in box. Finally got it working after search youtube. Stopped working when wifi ( as a result of nbn outage) and haven’t been about to get it going since. Assuming battery supplied was depleted and can’t make any further suggestions until I purchase a battery - not a common one you have around the house so buy a few for future replacement

I finally caved and got some "smart" sensors for my home after being away during a cold snap and being unsure of the condition of my house. Having your heat go out or an undetected water leak is awful so while these detectors are a little pricey, I think it's a worthwhile investment especially if you're away from home regularly. I will say that the setup app and pairing process was way fussier than it needs to be. I bought an ecobee thermostat and that was way easier to set up, and I had to wire that thing to a furnace. I consider myself very technically inclined and the amount of pairing errors I got trying to set up four of these things made for a nightmarish afternoon. This is a single-instance pain point, though, and ever since these things have just been quietly monitoring. Battery life seems great - virtually no change in the last three months - and it's nice that the app reports a more precise reading than just "good" or "low". The configurable alarms are nice too so that you don't get nuisance alerts for high humidity in a bathroom when someone takes a shower. It'd be nice if using the remote sensor didn't block the ability to use the base unit's sensors so you could monitor a wider area, but the cable on the remote sensor is long enough that you should be able to find a good monitoring position. Overall, I'd recommend these to pretty much everyone. The earlier you can respond to an emergency, the less damage you'll likely have to deal with.
