Moat New S2 Wireless Temperature & Humidity Bluetooth Smart Sensor (iPhone/Android) - Thermometer/Hygrometer. Monitor Climate for Your Home Refrigerator Humidor Reptiles Guitar (Black 2 Sensors)

I received these today and they aren’t what I ordered, kind of. Yes, I ordered a two pack of these temperature sensors. However when I opened the Amazon shipping box, I immediately noticed the package was tampered with. Upon further looking I found a sticker that reads “refurbished.” I ordered and paid for new, not used. I looked at my order again to make sure and nowhere was refurbished written. Next, there was no literature in the package. No instruction manual, no nothing. I had to go online to figure out how they work, what app to download, and how to connect to them. I will say that once I was able to figure that out, they seem to work as advertised. I placed them side by side and their readings were almost identical. I then placed them in my fridge and freezer and they worked fine there too. So thumbs up to functionality (so far) but thumbs down on getting a used pair with no information.

This device was the easiest to set up. I use one in my newborns room and one in my milk chest freezer. Piece of mind that both are at the ideal temperatures. Super easy to navigate app and was able to label each one.

One would think that in an age of electronics, there would be dozens of brands of wifi temperature sensors. There isnt. Most are bluetooth which requires you to be close.I bought this because of periodic power outages at home. I wanted to not just be able to see the current temperature from outside my home, but also the historical temperatures. If power goes out for hours, food in a refrigerator could be spoiled but when the power comes back on, it could be a safe temp when you check at home.This product does its job. I have one sensor in each refrigerator and freezer. I calibrated them with an analog thermometer and they are within a degree or so. The analog could be the one that's off though.Setup was generally very easy but one of the four sensors I got had some difficulties. In the setup program it tells you with an arrow to put the sensor aside your phone. They really do mean right next to your phone.The phone interface is pretty good but could be better. It allows you to set optional alarms for minimum and maximum temperatures with a slider. The slider is somewhat imprecise, so up and down arrows or an input box would be better. One of my freezers supercools periodically for no apparent reason (-20°), so make sure you also set an alarm for the minimum temp in a freezer.The historical temp chart is ok but could be better. It appears to have automatic scaling between the relevant range of temps, but this doesnt always work. That is, while the temp in my freezer might stay close to zero degrees, the scale shows -43° to 96°. It should automatically narrow to like -25° to 25°. Because it does not do this, the history is sometimes hard to read.Another problem with the historical chart is that it does not show the date. That is, if it is currently April 3 at 7am, scrolling backward to 7am on April 2 and April 1 does not show those dates - just 7am. You have to keep track of the date in your head.There is also no way to clear the history.Fairly often when I check the temps, there is the spinning wheel of trying to refresh that seems to go on forever. I'm not sure why this is the case. Is it the sensor having problems? Bluetooth or wifi having connection problems?The settings frustratingly allow you only to change from Celsius to Fahrenheit. Theres got to be more user options.Overall the product works exactly as I intended it. While writing this review, it occurred to me that the wifi hub is plugged into an outlet, so in the event of a power failure, I might not get the information i need. I will have to check whether the hub has a battery backup. If not, I may need to add one. But my internet might also be out. The extent of this potential problem is that while I might not get alerts when I'm out of the home, at least when i get home I will have a consistent history to see if food was spoiled.I've seen no competing products at comparable prices that could be better, so I have very little buyers remorse.

I like the size of the sensors. Conflicting data on Amazon whether these use a CR2032 or the CR2477. Then Moat’s website says it is a CR2450, so who really knows what China junk they are sending out. I will not be opening one up to find out which battery though and will be returning them. The sensors were already live when I got them, even though they were in their sealed box. They tracked almost 2 months of data, but no telling how much longer they were on before I received them.The app is painstakingly slow to update. If you want to review past data, you have to fetch it for each individual sensor you're connected to, no way to mass update. Then, your app only shows the temp on the hour and you have no way to change it. If I want to log it every 15 minutes, it should be able to do so and then overwrite old data you haven't downloaded. I couldn't test the app before purchasing as it forces you to pair a sensor before seeing the layout and options. I would have saved myself a purchase and return.

Bought this little gadget to keep tabs on my cigar stash. Works awesome by telling me where my humidity levels are at. If the bovea pack is needing replacement this device will notify me! Great perchase.
