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

Works just as it's supposed to. I'm confident they're accurate as well. I'm using them for personal use, so I doubt I would ever send them for calibration, but compared to the "pro" unit in the Quality lab where I work, these things are spot on.They were super simple to setup. They seem very sensitive - I breathed on one and the temp/humidity reading clearly reacted. I have one in my crawlspace where my water heater is, so I can monitor the winter temps to watch for freezing pipes and I can easily take a reading at any time. I had left one in my vehicle when I parked at work and checked on it during the day, hooked right up. They're also really handy to use in the tented booth for my 3D printer, tobacco humidor, and dry boxes.Great quality, highly recommend.

Bought a few more to put on all floors including the attic and basement. Easy to set up without signing on. Work fantastic. Helping me keep the house thought evenly warm and perfectly humid throughout the year.Easy to set and adjust preferences in the app, too.Very happy ⭐️⭐️⭐️⭐️⭐️💯/\ update againRepurchased a two-pack because the first detector has worked so great.These dual additions are working as well.Quick set up in the app without signing in. Mentioning this because of complaints about personal info.It's very easy to name each device depending on the room.Once set up it's very simple to set the temperature and humidity range alert. Meaning the blue numbers mean desired and the red beware.This is important to me for guitar management and pet support. Plus, maintaining humidity helps deter dry lips and skin in colder months. Warmer help me set safe humidity for daytime animals inside and sleep temp and humidity.Because we're outdoors often like more humidity and higher temp indoors during summer and cooler in winter. Makes adjusting outdoors easier. But always require a higher humidity in winter for the guitars.These help me know when to turn on the ac for the pets or individual room heaters. A few have temp guides so this helps.In a house from 1900 central air doesn't work because the house isn't designed for it. Or heat. It’s cold in the summer in most rooms due to the design pre ac. But the humidity is a pain to follow. If I'm out for the day want to ensure it's safe for the fur farm. Like, when to set the portable ac in each room to maintain 75% humidity.I'm adding details to emphasize how these little detectors can help in large older vintage houses that aren't built for modern equipment.This modestly priced device makes ensuring comfortable humidity for instruments to animals and plants plus people perfect, in my opinion.These device readings all in one app for me are very helpful in this larger house four-story building to maintain ideal humidity and temp any time of the year./\ updateI've used this detector for a few years. It works very well. Back to buy more for other rooms. There are more expensive versions. For me, find this works just fine.As long as it's not attacked as a toy by the cat 😁 Even so it reassembled and kept working.As long as it isn't hanging where a playful kitten can access it all will be well.In regards to the security comments, I use the detector with the app but do not have it set for a location unless I'm checking the humidity. It works fine to get a reading on the app.Go to settings on the phone and click while using the app. See pic for what I mean if you're tech-challenged.For those concerned my encouragement is don't be in Amazon either. Have no email or any online accounts. Close the bank accounts, house payments, and stop visiting the doctor. Etc etc.Unless you're John Connor from Terminator your info is accessible. Is accessed.Amazon kicks back reviews when I pitch other recommendations. So all I can say is there's a book by a guy that talked about the art of invisibility. The way to set up without being hacked or tracked.Using this all isn't going to end the world as you know it. Adjust the location setting and minimally you'll get a temp and humidity reading.For me, this is important for guitars and to maintain comfort especially in winter. Of warmer months for the pets. Helps me know when to use the air for them. Plus close the windows for better sleep if it's too humid. Works great while traveling, too.Humidity or lack there up isn’t easy to detect naturally, but when it’s absent or higher then is comfortable could hurt guitars and fur fam when I’m gone for the day or were traveling and the instruments are home.Enjoying the outdoors prefer natural weather vibes inside. Except when it’s too much or too little.This little priced right device is just right, in my opinion⭐️⭐️⭐️⭐️⭐️💯

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).
