Govee Smart Bluetooth Thermometer Hygrometer, Mini Humidity Sensor 3 Pack

With rising home cooling costs and a roof that has no shade, I need to find affordable options that will reduce heat in my attic and help the hvac system from overworking to cool the second floor. I put 2 of these monitors in the attic and the third in the room that is the furthest from the hvac system in the attic. The results are very telling. These are Bluetooth and although the paperwork says they can be checked 262ft away on the app on my phone, because of walls I guess, I have to go up stairs to check the one that is the furthest away-no problem. Govee makes great products. I have WiFi water sensors that I am glad to have under every sink and behind every commode. If there is a leak and a drop of water hits any of them, it will sound off and a message pops up on my phone. A leak can be detected and the issue resolved quickly. The app also alerts me if a battery is low. The leak alerts have AAA or AA and the thermo/humidity sensors have lithium batteries. The app is easy to use and all mine have names the state their location.

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 Not a product issue but a phone issue is that my widget for the Govee Home App displays an outdated temperature and to get a current accurate reading you do have to open the app to update.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. WIDGETS I 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. PERFORMANCE Aside 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. INSTALLATION The 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. BATTERY The 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).

I got the two pack. Set up was trivial and they work as intended (tracking temp and humidity). Not much more to say - it's nice to have something simple that just works. The app is more complicated than it needs to be, but the extra functionality doesn't get in the way.

I use this to connect to the Govee app to control my Govee humidifier. It tells you the temperature in the room how much humidity is in the air and can also be used to trigger my humidifier. It connects via Bluetooth to the Govee app. It could be used to control other devices that you might have. It can keep up to three weeks of logs on the temperature and humidity in your room or in its location. It comes with its own little battery that you activate by pulling out the tab and it’s so small you can hang it on the wall and not even notice it. I’ve had mine for several months and I have not had any to replace the battery. It doesn’t have a display.

These do a nice job and they were much smaller than I had expected which was nice. I knew they were bluetooth but didn't think about the fact you need to be nearby them to read/update and this is also a manual process, so you have to go into the app, and into each of the sensors to get the updates. Not a big deal and I guess I should have know this being bluetooth, but wanted to share in case you are not thinking about it. Overall I like the sensors, the app and the results.

As the title says, I bought this to replace some non-bluetooth hygrometers that never really agreed with each other for my humidor. For the price I paid, this device is excellent value. The one I got seems to be reasonably accurate (much more so than the $10 cheapie digital ones that come with a lot of inexpensive no-brand humidors available). Bluetooth connectivity works from anywhere in the house, and I don't have to open the lid to check in on it. Has historical tracking in the app. The app itself is interesting. Govee appears to be trying to establish itself as an actual brand that a consumer might intentionally seek out, and the app is more extensive than a lot of the apps that accompany inexpensive electronics. It seems plausible to expect support to be more robust than one-device-only apps. It still manages to do a relatively good job at surfacing only devices you actually own, which is also nice. Additionally, for this device, it provides all the functionality one would hope for. In addition to historical tracking, it has an alarm function which allows setting any range you'd like. I haven't tested that thoroughly yet. Hopefully the alarm is in the form of a notification than an audible alarm from the device. Which brings us to one issue with the device/app, it has been indifferently translated. It's generally easy to understand what they were attempting to say, but that's about it. At any rate, I like this device enough that I bought one of their more expensive wifi models for a different, remote application. Update: After six or so months one of the three I bought no longer reads humidity correctly. They’re still cheap and convenient enough that I like them, but I updated the score to reflect that they’re only ok-ish.

TLDR: Small, light weight, very accurate and outstanding support. Pros: It is small and easy to place wherever you may need it, ie humidor. Accurate measurements of temp and humidity out of the box without needing calibration. Easy to obtain and export data from the app and see trends over different time scales. Stores multiple days of data so if you don't open the app every day you can still see the trends/readings. Excellent customer support. Cons: Bluetooth only so you do need to open the app every couple of weeks to see the data (they have a Wi-Fi model however). After a year the accuracy began to fall so I would recommend confirming accuracy every 6 months or so - though I will add that this is better than any other thermometer/hygrometer I've used. My experience: I've been using this for 15 months now and am very pleased. I checked the accuracy of both the humidity and temperature when it arrived and it was spot on. After a year of constant use in my humidor it finally gave me an error and stopped working. When I contacted Govee they immediately sent me a replacement. I checked and the second one was just as accurate as the first. I'll be purchasing more to monitor temps throughout the house so I can adjust HVAC vents.

Very useful

Bien

Compré este hygrómetro para monitorear la tempreratura de mi cuarto de fermentación (cervezas, sidras, hidromieles, etc...) y la verdad es que ha sido muy práctico ver el comportamiento de la temperatura, lo cual voy a poder correlacionar con algunos efectos en el proceso. El dispositivo en sí es sumamente pequeño y puede ser colgado en cualquier parte y olvidarte de él hasta que realizas la sincronización bluetooth, algo que estaba buscando ya que en ese lugar no existe una conexión a internet.

Pros - Very responsive. Feels robust. The app is great with big Temperature display and customisation has widgets. Updates every hour. Can set alarms if the temperature falls for increases. It can be recalibrated. Meh - Value for money. (could be cheaper) Cons - links to only 1 device at a time. The white cover gets dirty easily. No reading on the device.
