Bluetooth Hygrometer Thermometer, Wireless Thermometer, Mini Humidity Sensor with Notification Alert, Data Storage and Export, 262 Feet Connecting Range, 2 Pack

We purchased three of these mini Govee Bluetooth hygrometers to monitor humidity while running the air-conditioning, which had been drying out my husband’s skin. Our target is around 48% humidity, and these sensors have been spot-on across multiple rooms. Setup was simple since we already use the Govee App. This model connects via Bluetooth only, which works well for our home layout. At the time of writing, the product listing incorrectly says no battery required - it actually takes a CR2477 battery, which is included. The battery compartment is secured with three small screws, a thoughtful safety feature that prevents children or pets from accessing the button cell. Performance has been reliable and consistent. The temperature and humidity history in the app makes it easy to spot trends and adjust the environment. For the price, it’s excellent value+ simple, safe, and accurate.

Had my for 9 months and works flawlessly. Mine is Bluetooth and always gives accurate feedback on the temperature and humidity. I just threw mine in my Humidor and it just works. Give it a couple hours and everything reads correctly and accurately. For me I did not have to calibrate either… very happy

Good thermometer for a great price. I use it to monitor medication in my mini fridge that needs to stay between 36-46F. Very accurate and always matches the analog thermometer I have sitting next to it. Tiny and compact, easy to set up, and wireless with good Bluetooth connectivity. The app is pretty nice with a decent interface, the ability to set an alert if the temperature drops or rises outside of a preset range, and a graph that allows you to go back quite far to track temperature fluctuation. The only downside/weird thing is that it’ll randomly send a notification that the temperature is crazy high (between 1000-2000F) which obviously isn’t the case, but opening the app displays the correct temperature and the spike isn’t even recorded in the chart. It happens maybe once every few days and just seems to be weird app bug. Otherwise, great device and definitely worth the price.

We love this Govee thermometer and hygrometer. It works great and provides accurate temperature and humidity readings through the app with no issues. The Bluetooth range is more than enough for our needs, and the alerts are very useful for keeping an eye on conditions. The small size makes it easy to place anywhere. Definitely a great purchase.

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.

Worked for about a week. Would not connect. Deleted device from app. Attempted to reinstall….couldn’t be found. Determined the battery is dead. Ordered a new battery. Hopefully this cures the problem. Will update review later. Update: battery not dead after all. It would not connect because it was connected to my iPad. Lesson learned. 5 stars

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.

Very useful

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.
