Govee Bluetooth Hygrometer Thermometer, Wireless Thermometer, Mini Humidity Sensor with Notification Alert, Data Storage and Export, 262 Feet Connecting Range

Dog owners should all invest in these. Easy to hook up to phone to monitor temp in crates in the car. In AZ heat it helps so I can run air and get temp down before putting dogs in car for a trip. I’ve found it to be accurate and functional, gives real time updates and it is a good investment.

Highly recommend. I'll start off with noting one of the most useful things that happened within a month of owning this freezer thermometer. The power went out but it happened while we were not home. I was able to look at the temperature readings to get an estimate of how long the outage lasted and if any food was affected. I love having the temperature graph to see if the temps dipped higher or lower than they should. It's very easy to read and keep track of. It also shows you the battery life which is great. Not a product issue but a phone issue is that my widget for the Govee Home App displays an outdated temperature and to get a current accurate reading you do have to open the app to update. I've had no issues with connecting to the app from any location thus far.I had bought a different brand before but didn't realize it required a hub to function. Not the case with this freezer thermometer. It is a small cute size so doesn't take up much space and has worked well. I do have a manual thermometer to compare against for temperature accuracy.It says it handles down to -4 degrees Farenheit which is true. My freezer dips below that frequently maybe up to -9 degrees and the thermometer is still kicking. But again it's only been a month so we shall see how long the battery lasts being pushed.

I got this sensor to create a simple "information center" out of an old iPad, for use in my RV. This just involves setting up the "home screen" of the pad with widgets from various apps like weather, calendar, etc. Using iOS widgets lets me make a flexible, easy-to-read display that's user friendly without any special software or setup. Importantly, it uses BT instead of WiFi, since I don't have a router in my RV. It mostly gets the job done and for the money it's hard to complain. It could be a little better, though.WIDGETSI chose the Govee over all others because it was the only option I found that offered iOS widgets. The widget has Dark and Light mode versions, which is nice. There are small, medium, and large sizes. The small can display one sensor; the other two display multiple sensors. You get sensor name, date and time, picture of the device, temp readout, and humidity readout...which is actually too much.This does meet my needs, but I'm disappointed that the most important info -- the temp and humidity -- are very small and hard to see due to sharing space with all that extra info, and especially the picture of the device, which is *pointless since it never changes*. Widgets should display whatever the app specializes in ONLY, not a whole cluster of the same redundant info I can get anywhere else. It's like having the clock on the wall, on the microwave, on the DVD player, on the coffee maker...I'd prefer to see only device name and measurements. The smallest widget would ideally (for me) show just one user-chosen measurement, allowing very customizable and easy-to-read layouts. The other widget sizes are better suited to fitting in more measurements and/or more sensors. I hope Govee will add easier-to-read widget options in a future app update.PERFORMANCEAside from this, the device itself performs fine. I have no "calibrated" thermometer to compare it with, but the numbers agree with various other devices and they update often. If I pick it up in my hand I see the temp go up pretty much right away. I'm happy with how compact it is.Setup was fast and easy. No registration or signup required to add the device to the app, and connecting to the sensor went smoothly. I The instructions are written in a way that seems like you can add a sensor directly from the app, but in iOS at least you need to pair to the sensor in Settings (the conventional way) before the app will see it. This is plenty easy.I have my sensor in an exterior compartment that's enclosed in metal. It's only about 10 feet from my pad but there's quite a lot of obstructions between them, and I have no trouble with the connection.INSTALLATIONThe device itself is surprisingly small; only a little larger than its widget displaying on my iPad! This makes it easy to slip into just about any spot. The only physical change I suggest to the case is a second mounting hole, which would make it much easier to secure against movement and vibration. The hole is located on a face that's angled so if you try to (lightly) secure it with a screw, it doesn't sit flat - the beveled edges of the case make it "wheelie". A second hole (or simpler case design) would help with that.BATTERYThe batteries are CR2477 coin cells, which are a rather large and totally unfamiliar size of coin cell for me in the US. One cell is about the size of 4 US quarters stacked up. These are tough to find in local stores (though of course AMZ has them) but their energy capacity is almost 5 times that of a common CR2032 so I expect they will last quite a while -- though I haven't had it long enough to say. I don't know if it sends a "low batt" message to the app/widget (but that'd be a nice feature).

It works, even installed inside of a stainless steel refrigerator!I originally purchased the thermometers for the refrigerator & freezer for our RV and initially installed them in our stainless steel refrigerator at home for testing. I liked them so much, will likely order another set for our house. Bluetooth connectivity is great, am able to read the devices ~40 feet away without any problem. What I also like, is if it loses connectivity, it will tell you, (via loss of signal from within the application) vs. other wireless devices that I've used simply report the last known reading.Initially, it would only recognize 1 device so I had to contact Tech Support which was very responsive and after following their instructions, (turn Bluetooth setting to Always and reboot the phone) they now both work. They are small, so are perfect for RV applications.

So far I absolutely love this I've only had it for a day. I'm not seeing anything about a subscription yet like reviews complain about. This thing is awesome and accurate from what I'm seeing. I have it in my ball pythons terrarium item came recommended by multiple ball python owners and snake owners. Puts my mind at ease with the issues I've had since getting her. I don't have to run back n forth anymore or cut time in half when we're doing things away from the house to go check her temps and humidity. It's worth every penny I plan on getting a few more. I will give an update once I've had time to fully test the product but overall very happy well worth the money.

Bought for my motor home to keep an eye on what the temperature is like throughout the day and night. Works pretty great for what I need. I only wish that the range of what it reached to read the temperature was further.
