5.0 out of 5 stars Great and seemingly accurate, with decent app for phone

The latest two being recently bought as a "two pack".The yare so simple to connect to a mobile device, needed if monitoring, recording, graphing and any offset needs to be applied. The mobile app can also update the firmware, if applicable, and has done so on more than one occasion with ours.The display for each unit is large and easy enough to read no backlight tho. There is a single button on the top, to switch between imperial and metric. Whilst you can read the RH and temp, along with mins and max of each, you will need to use the app for your phone connected to the device to read information like the dew point and to see graphically trends etc.If you buy more than one device at a time I strongly suggest just trying to set one up at a time. Especially when connecting and pairing it with the app on your phone. They do NOT have a MAC code for each device, so I set one up at a time, leaving the batteries out of the others, and when that one is connected we then place a label with its location on the back.If you try and connect all of them at the same time, and the yare grouped together, it is difficult to know which units display within the app relates to which unit.See my photos of what is contained in the "two pack" box and also how we have ours setup, and labelled.Looking at the graphical information we can see "averages" or set to show "highest" or "lowest" temperatures.The one noted as being in the rear garden is under a canopy and away from prevailing winds.The Bluetooth range is typical of what you would expect. We live in a larger house, so no one place can reach them all. That is not a big deal, it just means I will access and update the information in the app as I feel is appropriate.Remember these are not Wi-Fi, they are BT in their connection. So manual updating is necessary for the app to be updated. We can update ours from the rear garden, or the attached garage on the side of the house, through the adjoining wall, the one on the rear garden, from a window in the room adjacent to the garden.I have had several of ours and used them continually for a few years. The batteries last a long time, with an indicator within the app showing how much drain the batteries have.I did set an offset for the one in the kitchen, about -1.5c. That was so it would agree with the rather inaccurate Hive unit, that controls our central heating. Along with the one in garage, where our boiler is, we can ensure that the frost guard settings are working as needed. To protect the boiler and the sytem.The app on the phone is good, if a little bloated. Everything gets installed, meaning if you only have these Govee devices then you have to accept that it can be used to control so much more .Not a problem, just mentioning that.There is nothing that I can consider negative about these devices. Understanding the limitations of BT and its range etc, then all is good.Overall, I very much recommend them.I do hope that this review has been helpful.Happy shopping.

5.0 out of 5 stars Impressive IoT device even without their app

G. · 24 January 2022

I bought a pair of these after reading a blog where the bluetooth LE features were examined. One of the most impressive features is that they don't need to be paired with a phone or tablet - out of the box, they actually broadcast their readings every 2 seconds. So if you set a bluetooth device to receive broadcasts, you can just plug and play - no downloading privacy-infringing apps to your smartphone, no making accounts with the manufacturer for no reason. I adapted the code to do exactly that - receive the readings and store them in my own database (MariaDB), then I can use my existing Grafana setup to display the readings. No security concerns because they're bluetooth, not wifi. I have a Raspberry Pi receiving the broadcasts, processing the readings and then logging them.I have 6 of these around my house now. They respond extremely quickly - the changes in temperature and humidity are visible when I walk into each room. Their accuracy is remarkable for such cheap devices. The data helps me figure out how effective my heating is and where I can reduce it. The batteries also seem to be long-lasting. The LCD is big, easy to read and also updates as quickly as the broadcast readings.Any downsides? It would be nice if the bluetooth MAC address was printed on the devices. I had to figure out each device in turn, but that was a one-time labelling. Now I have labels on each sensor, I can tell room by room what's going on in my house.For the money they are ridiculously good. And bluetooth range is great in a 1-bed house. In fact, 6 devices broadcasting is enough to degrade my 2.4GHz wifi! I don't know if the range claims are accurate but they're perfect for my use case. Very pleased.

4.0 out of 5 stars Fantastic little smart temperature / humidity sensor for the price

A. · 1 January 2021

I have always had a fascination with knowing the temperature / humidity of a room so got myself one of these after seeing it on offer prior to xmas. I have used various temperature sensors over the years such as: Ikea Klockis, Ikea Filmis, various wireless weather stations so i like to think i know the general flaws these types of products suffer from. I liked this unit so much i got a second one for my conservatory and one for my dad as a gift after owning my first one for a month.Positives:- The LCD display is extremely clear and easy to read with big digits and great viewing angles. Normally these products tend to suffer from poor viewing angles or dim faint displays but this is not the case here which is fantastic. I also love that it displays the high and low values for each reading, this is a nice touch.- The unit comes with a nice looking yet discrete design and a nifty pull out stand. Build quality is high considering the price.- Pairing of the unit is very simple and range seems to be good and reaches across the entirety of my two bedroom house. The controls are simple and allows for reset of temp information as well as toggling between celcius and faranheight.- Temperature accuracy appears to be on par or superior to other units i have used, i got all of my other devices and placed them side by side to compare readings. The software allows for calibration adjustments if the readings are a little out.Negatives:- The app is functional and powerful but appears to be a re-skinned 'Smart Life' app so contains a lot of bloat with a cluttered design with adverts. A simplified clean professional design would be better here.

5.0 out of 5 stars Can’t fault it!! 5* Product

I’ve been using this for 2 years now and it’s still going strong and giving me well needed data for maintaining humidity in a damp room. Love the app, very useful so I can easily track stats over the months and years. Spot on readings that match our top brand dehumidifier

5.0 out of 5 stars Bargain product

For a Bluetooth this works really well for onside monitoring, works across 3 house levels pretty much all the time and the app is really well laid out with good visuals and easy set up. Would look atmore products from Govee in future.
