Smart Bluetooth Thermometer Hygrometer, Mini Humidity Sensor 2 Pack

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 again Repurchased 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. /\ update I'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 love these. I have been using these Govee sensors for nearly three months now. I have 9 of them set up in my reptile/amphibian enclosures. I think they work for what they are, but they aren't perfect. Removing the battery tab and setting them up is really easy. You need to have their app. It walks you through setting them up. I had a problem ONE time with a sensor not turning on. These units are not sealed shut. You can open them with little effort (i pulled it apart with my fingers). The board inside is not adhered in. You can pull it out and adjust the battery with no problems. Once I did this, the unit worked fine. I have checked the accuracy by comparing the temperature with 2 standalone temp/hygrometers. One from accurite (commonly recommend by reptile groups) and one from La Crosse Technologies. What I found is that the sensor is accurate within 3 +/- degrees and 1-5% humidity. They do take some time to update. For example....if you spray your tanks, it can take 3-4 minutes for the adjustment in humidity to reflect on the app. The connection is via Bluetooth. You will not get readings while you are "away", but you will get data from when you were gone when you connect. The biggest problem that I have with these is that the information does not always update in the background or when opening the app. Sometimes, I will show readings on the home page from 2 different days. I have to click on each individual device for it to connect and update the information to current. This tends to be a problem maybe 2 times a week. The app has some features that are kind of social in nature. They have testing offers, promote products, do giveaways, etc. I don't really use this.... I don't really care what Stanger I've never met named Steve in California did to his van with the strip lights that Govee sells. Happy for him if he's happy, but otherwise I just don't care. I needed to contact support one time because the app offers coupon codes from time to time. When I attempted to use the code, it would not let me. I contacted support. They were... not super helpful. The communication seems to be a language barrier. If I had problems with the units themselves, I can see this being a big issue. Overall, pretty happy with these. I bought my first one at full price but have gotten the rest on sale. I recommend waiting for sale prices.

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).

This is an excellent product. I monitor my NoBo 20.3 Travel Trailer that is 7 miles away to assure Temperature and Humidity are ok. I am hooked into the WiFi of the Storage Facility with the Item and I can see the information from the Govee anywhere. I was checking in on things from California when my trailer is in Washington. Worked perfect. You can also just Bluetooth it to you iPhone as well, but you cant see information from more that about 100 feet. I now have 3 of the small Govee Units, and One of the Larger ones. The App is Free and simple to use. 8o)

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.

Works well. Bluetooth connects over 30 feet away through walls. Good monitoring of temperature and humidity. Keeps an internal log between downloads.

This device is easy to use, accurate and convenient. It is however, not built with your security in mind. This is the reason for one star. First, it requires the use of their "Govee Home" app, and only their app. This would be fine if the app provided some semblance of being secure, but it does not. First, it wants to know your location, the app will not start without that "vital" connection. Why? Who knows for sure, but the second requirement is the kicker. Even though this device is a Bluetooth transmitter, THE APP WILL NOT RETRIEVE THE BLUETOOTH TEMPERATURE DATA UNLESS YOU ARE CONNECTED TO THE INTERNET via WiFi or cell data connection! That's right, a BlueTooth-only device - that only transmits temperature and humidity readings, that's it - needs to talk to the internet through your device for some odd reason. This is without signing up for an account on their system, which they want you to do to get the CSV data for a spreadsheet. If you have one of these little gems, you can test this requirement by using a tablet for the app and turning off your WiFi connection for an hour or so, then try refreshing the temperature data. It will give various errors including "Network not available...". Upon turning your WiFi connection back on, refreshing the graph in the app will *instantly* show all the data since you turned it off, up to the minute you turned it on. Yes, BT was on the entire time, and other devices could be seen over that BT while the WiFi was off. So what is it that is so important for the app to do that it needs to talk to the mothership before I can get a temperature reading from my attic, which is all I bought the device for? Thankfully I use this app on a cheap, old factory-wiped tablet with a dummy account, that has no other uses anymore. I suggest that if you, like me, decide to keep this device, and thus are forced to use their app, you should do something similar with an old (factory wiped) phone, etc.

I’ve had the H5074 for three years or more, so I figure I owe a review. Unlike a lot of the reviews I see here, I have a very limited — but important — use for this thing. I have a large free standing cigar humidor in my upstairs study. But we live downstairs. And since I’m now retired, I am rarely upstairs checking on the humidity in the humidor where many scores of cigars reside. I say scores, but it has to be a couple hundred cigars. They mean a lot to me even though I do not smoke many any more. But it’s nice to know they’re there, waiting for me to smoke them or to provide them to a guest. Anyway. the point is that I easily keep track of my cigars’ health with this Govee. It is very reliable and well worth the expenditure. I highly recommend it

Very useful

Funciona muy bien. La aplicacion es facil de usar y si me dio la opcion de que nadie mas se pueda conectar al sensor. Lo puse en el refrigerador y me ayuda a estar al pendiente de la temperatura. Puse la alarma de temperatura alta y si me avisa cuando pasa del valor que le puse.

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.
