Well... there is no decent review for this device, so I will say a few more things (Prepare).
First of all, regarding the device, as others have said, it is a Chinese rebranded one. It is not of high quality, nor is it very sturdy. The external sensor has a screen for humidity/temperature, which I think is not easily found, but for some it may be unnecessary.
The internal unit has a large screen and you can see everything at a glance, without having to press buttons. In terms of viewing angles, when we talk about left-right, everything is readable, you have to look at it completely from the side to say that you can't see anything. Now, regarding up-down, there is an issue. I placed it on a countertop that was about 1 meter high, and when I sat 2 meters away on a chair, I could hardly see anything, but note that when you use the stand, it tilts backwards, which makes things worse. If it is hung on the wall straight, I don't think there will be a problem, but either way, standing up, I could see everything from everywhere. On the top of the device, there is a sensor where if you wave your hand over it, it changes the brightness to the maximum for a few seconds (if it is not already adjusted). It can also be used to snooze the alarm.
The brightness increases quite a bit, but don't compare it to those with only a black screen, they have no illumination at all and you can see everything (and the batteries last for years). In this one, if you turn off the illumination, you can't see ANYTHING, unless you have 20/20 vision and stick your nose on it. In addition to this, I will add something else that no one mentions anywhere: If you want to use it only with batteries and not with a power supply, the WiFi will NOT work (meaning the reason you paid 60 euros). With batteries, only the temperature and humidity work for indoor and outdoor.
Now let's move on to the setup... Here I will mention that the instructions are as if they were written by monkeys in English... and in Greek, it's like you took the text from the monkeys, threw it into Google Translate, and copy-pasted whatever came out. In short, you can't make sense of it, everyone complains for the same reason, and I will try to give the steps that I believe I have put in the correct order because I struggled for quite some time and lost my way.
0) We put batteries in the external sensor, switch it to position "1", select Celsius/Fahrenheit degrees with the corresponding button, and leave it aside.
1) We download the "WeatherSense" app (FuZhou EMAX) on our mobile phone (yes, the one with 2/5 stars).
2) We register an account and log in.
3) It asks us which device we have (it has 2 options), we select the first one that says "001" (here they probably have the Chinese models, but they renamed it to "WES-401", so good luck figuring it out).
4) We plug the device into the socket (WiFi only works with a power supply, not with batteries) and it automatically goes into AP Mode (it flashes "AP" on the top left, if it doesn't enter automatically, hold down the WiFi Button for 3-4 seconds).
5) On our mobile phone, it tells us to select a network, we select our home WiFi (the manual says it does not support 5GHz networks) and enter the password, then press next.
6) It connects, we press Confirm, and it shows us a map with our location (it gets it from GPS if we accepted when it asked us).
7) We confirm or drag the map to set the correct location if it's wrong, and press the button on the top right that says "Complete" if I remember correctly.
8) Now either it works and you rate the review positively, or I made a mistake and you curse at me.
The two most serious problems I encountered were:
1) On the first mobile phone, it didn't pair with me, it constantly showed errors with the functions we mentioned. I don't know why, maybe some security app blocked it because I have various ones, it worked directly with another mobile phone (after pairing, I logged in and saw the information normally from both phones).
2) When I was exploring the application trying to figure out how it works, it crashed frequently (After the setup, it didn't present any problems again).
Through the application, you can see temperatures/humidity inside and outside wherever you are, and all the other information that the device has. You can also set it to send you notifications for extreme values and it has graphs showing the temperature/humidity trends for a day/month/year.
I don't know how often the Chinese will update the website where the device gets its data from, and how often they will release updates for the mobile application. Time will tell.
Some people complain that it doesn't synchronize the network data sometimes, etc. I have only had it for 4 days, but it works perfectly. Overall, for what it offers at this price, I believe it is worth it because you can see everything at a glance (Temperature/Humidity inside and outside, barometer, date/time, and from the Wi-Fi, wind direction/wind speed/feels like temperature/visual representation of current weather/forecast for the next 4 days with higher/lower temperatures and visual representation). If these features are not enough for you, you should probably look for something more expensive.
Something similar with a color screen at this price, I don't think it exists, if it had proper instructions, I believe it would have a much higher rating (both the device and the application), even I, who deal with technology, had difficulties. Since it was set up, everything works correctly, the temperatures are almost the same as with 3 other thermometers I tested, so they should be quite accurate, and I am satisfied.
If anything else comes up in the future, I will update. If not, it means that everything is working as it should.
tl:dr.... there isn't one! You have to read it ALL! Or at least the steps for the setup if you want to maintain your peace of mind.

Now I have had it for over 9 months and I have never had the slightest problem/desynchronization.
The weather forecast is generally good but not perfect. The worst thing I noticed, for example, was this summer when it was raining all over Greece for a period of time.... but not in the area where I live! The weather forecast showed storms everywhere for a week and I had sunshine outside. I double-checked that I had set the correct location/coordinates, I even tried other nearby areas for testing and it showed rain everywhere. I don't know from which meteorological station it gets the data for my area and how close it is.
Apart from this isolated case, everything is fine! Let's not forget how many times we hear the "experts" on television warning us about floods and then we have sunshine, or vice versa! There is no 100% accuracy, but for household use, in my opinion, it does its job honestly. If I needed another meteorological station at this moment, I would choose this one.
