This thermometer/hygrometer displays its data (temperature + humidity) in a large readable font. It is more accurate than many, thanks to its Swiss sensor.

I'm reviewing the SwitchBot Meter Plus two-pack which I bought on September 28, 2022. They come in nice boxes and 2 AAA batteries each are included. They have a magnet on their backs and come with metal stickers so they can be mounted to non-magnetic surfaces. Downloading the app and connecting them with Bluetooth was uneventful. After six weeks the battery levels were 97%. I am using them to monitor a refrigerator/freezer and they are working well for this. They connect even when the doors are closed which surprised me. Once they sync, the app shows graphs for temperature and humidity that can be zoomed in and out. It shows the high, low, and average temperature/humidity for the time period you choose. I don't have the hub so they have to synced manually which takes a while. If you just want to check them as needed the hub isn't necessary, but if you want to see the graphs of past values, the hub sounds like a good idea. Very impressed for the price.

I got this thermometer to help gauge the temperature, and humidity in the area for my plants and it has been very helpful! My plants now have the perfect temperature for them to thrive, especially in the winter. I've used this throughout summer, and it even helped me see how warm it was at home before I got home allowing me to turn on the AC remotely so the home is more tolerable before stepping in.

I have one in my attic. Was having trouble with high heat and discovered my attic fan was not cutting on. Once I replaced the fan I put the unit up there to keep an eye on the temperature and humidity. I put the other unit in the basement. Very helpful to gain insight as to how much humidity changes with weather.

Got up and running quick and easy on the app. I use it in conjunction with the Hub Mini to control my mini-split. Works well in setting the range to keep cool/warm my rooms. Also love to see the data recorded.

I love this huge screen and accuracy! have few other brand sensors over my house, but this one is most accurate when checking side by side with digital thermometer. also big screen is amazing, i can see numbers from far and don't have to move closer to check... also this is the only smart thermometer which actually works with my Alexa. would by more for every room for sure

Bought this initially to prove to my HVAC technician that my AC was not cooling evenly throughout the house during the night. They would come and use their thermometer and always say everything is good. With this, i was able to show them the data in different rooms during multiple nights and compare it with the set temperature in my thermostat and found out that indeed during the night the AC was not working as expected. Anyways, great product. does what it says it does and works amazing. I've been using it for almost a year and the batteries are still around 80%.

I bought one and then two more because I like them so much. The three read within +/-0.1 C and within 1% humidity of each other when placed side by side. This is very very good - even better than the specifications. They compare very well to other trusted temperature and humidity devices I have. The display is large and readable provided there is some light.
The best thing about them is that they are recognized by Home Assistant immediately after taking out the battery isolation tab! Set up in Home Assistant is painless and slick.
I don't bother with the app.
