The station is perfect, it does everything it promises. Where do I start? The screen is excellent, the graphics are perfect, and the weather forecast is always accurate. I don't know where it gets its updates from, but it has its own mobile application where you can see the temperature inside and outside, as well as the historical data. It has 20 different icons for weather prediction, wind speed in kilometers or miles, and 3 levels of brightness. The batteries it uses are extra, so even if there is a power outage, it won't lose its settings. I recommend using both the external sensor and the lithium alkaline batteries to avoid any issues with liquids. I truly have no words, it's worth buying.

UPD: So, on Friday, 16-12-2022, this particular station suddenly stopped receiving data in the afternoon. I checked if it was due to my home's Wi-Fi, but everything was fine. I was ready to return it, but yesterday, on 20-12-2022, it started working again. This station receives data from the internet, so if there is no connection, the only thing it displays correctly is the indoor and outdoor temperatures with its sensors. So, for those experiencing network errors or the station not receiving data, these are temporary problems caused by the server of the station. It obviously retrieves data from a website in China. Don't rush to return it, first make sure that the Chinese server is not down, or wait a few days

I have had the device for a little over a month and I can say that I am very satisfied with the purchase. I read the comments and ended up with this one, and I believe it is a good purchase in its category. The quality is not the best, the plastics creak, but it is a beautiful device and the screen is very good for color, although you have to be in a straight position to see the indications clearly. All weather forecast information is from the internet except for the temperature, which is wirelessly received from the external sensor. So far, I have been pleasantly surprised by the accuracy of the predictions, even though I understand that they come from some Chinese site and not from a well-known European or American one. The connection with the mobile phone is very easy with the weathersense, there are instructions in Greek, and it is useful as it keeps temperature, humidity, and pressure in data that you can download in an Excel file. One downside is that you cannot find an external sensor in Greece; I found one from China for 6 euros. Another strange problem, if I can call it that, is that the wind speed, which is supposed to be in km/h or mph, I noticed that mph corresponds to the Beaufort scale, at least it matches mine (I don't know if the firmware of the device has been modified for Greek devices). Finally, so far there has been no disconnection from the Wi-Fi. If there are any changes in the future, I will update.

1) It does not work with 5Ghz internet.
2) On 2.4Ghz, it tells me that I cannot enter numbers in the wifi password, even though I don't enter any. All of this happens in case someone wants to connect it with an extender, it works fine with the internet coming from the router.
3) If someone puts batteries in it instead of connecting it to the adapter and tries to connect it with wifi, it doesn't work because from what I understand, when it operates with batteries, it is simply to maintain it and not for many functions, which is why the wifi button and other basic functions do not work.
4) Its quality is quite good, but I noticed a sensitivity on the screen and on the plastic feet on which the station stands.
5) As for the external unit, it disconnected a few times even though it was quite close to the internal one. Apart from that, it works quite well when it is outside because if someone wants to place them side by side to see if there is any difference, it will show a deviation of 1 to 2 degrees, but I believe this happens due to some interference because when you use them normally, they work quite well.
Summary: It is a weather station with quite accurate measurements that, if you exclude the above-mentioned problems, in my opinion, someone can spend many years with it.

Update: Do not clean the screen and do not touch it too much because it scratches quite easily

15/12/24....It still works great...I haven't encountered any problems....and the mobile app works just fine....
21/3/23 The weather station continues to work without any problems. And the mobile app works just fine whenever I open it.

18/12/21. The weather station continues to function perfectly without disconnections or anything. And the new external sensor is working just fine.
AGRINIO 19/9/21. The weather station works great as well as the new external sensor works just fine.
14/1/20. I have had this particular weather station for about four months. The screen is quite good depending on the angle from which you view it, which has all the functions with nice graphics. The package includes instructions in Greek for the setup. Personally, I didn't have any difficulties at all. I downloaded the app on my phone, followed the instructions, and the app worked normally, as did the connection of the weather station with the router's Wi-Fi. Since then, it has been working normally. I have never experienced a Wi-Fi disconnection, and the app works just fine on my phone. I haven't encountered problems as other friends have mentioned. The forecasts for the coming days are reliable for the area I live in since all the information is from the internet. I am very satisfied with the device.
27/6/20.
The weather station continues to function perfectly. It hasn't had any disconnections, and the mobile app works just fine.
26/9/20. The weather station continues to function very well. And its forecasts are very good.
26/1/21/
The weather station continues to work as it did on the first day. It has never lost synchronization, it always downloads data, and the mobile app responds every time I open it throughout the day. Since I set it up on the first day, it hasn't given me any issues. It must have very good wireless internet in the area where it is placed.
29/3/21
The weather station continues to work just fine. For those who say it doesn't receive updates, do the following. Press and hold the Wi-Fi button next to it, and it will reconnect. Or unplug it from the socket and remove the batteries for about a minute, then plug it back in along with the batteries and wait a few minutes for it to download updates. Another solution is to turn off the Wi-Fi from the router for about a minute and then turn it back on; it will connect immediately. However, it has never frozen on me. It normally receives data.
30/4/21
For the past few days, the external sensor has been stuck. The red light is constantly on, and it displays nonsense on the screen. I removed the batteries and left it for a while, but nothing. I left it an entire day without batteries, but nothing.
15/5/21
I finally found a solution for the external sensor. Here in Greece, I couldn't find it anywhere. Just so you know if you ever have a problem with the sensor. We open the sensor and unscrew the three small screws to release the board. On the side where the screen is, there is a number right above it. With that number, we search the internet, and it brings up various sites from abroad that have the board. It costs around 12 euros.
16/6/21
In the end, the sensor from abroad never arrived. The order was canceled. But after a lot of searching, I found the sensor on a well-known site and they sent it to me for 6.5 euros please, not 12 which was the cost from China just for the board.

17/2/22
For me, it still works perfectly. With accurate forecasts and regular updates. And the mobile app works perfectly too. Also, the external sensor is doing very well.

I have purchased the product here for 1 month. All of its functions are completely useless. First of all, its internet connection constantly freezes. The weather forecast is interrupted and the controlling application is problematic. I have read and tried all the setup methods from various users, but the problems persist. In the 1 month that I have had it, it only worked for 4 days, during which I had to manually update the weather information by toggling the wifi and resetting the device (turning the power on and off). In the Play Store, all users are disappointed with the WeatherSense application. Even though I bought it with a 2-year warranty from a well-known Greek store, when I contacted them to return it because it doesn't actually work, they replied that it's not their fault but the fault of the Chinese who developed the application! So now I have spent 60 euros to buy something that only shows me indoor and outdoor temperature, something that I could do with less than half the price! It's a shame that products like this are sold, which in practice don't work due to lack of support, and people are being fooled. ALSO! The screen is completely unreadable when viewed from an angle from above or below. At a distance of less than 1 meter and with minimal angle deviation from above or below, nothing can be read! At night, with the lights off, you can't distinguish anything at a distance of more than 1 meter, the light is not visible no matter how much you increase the intensity. Buy something cheaper to do the same job. What a shame. I should have been more careful.

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.

23/12/2019:
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.

Does anyone know how to help?? I bought this product from abroad (for 36 euros) and today, on the morning of 14/01/19, it arrived in my hands. Of course, its name is FanJu, but it is the exact same product. The user manual is in English and I downloaded the Greek one so that I wouldn't struggle with it since my English is like that of a caveman. I've been struggling with it since morning. The setup without using the app, with simple indications of internal-external temperature, was simple and easy to do. However, when I tried to download the app, which was the reason for buying this, my problems started. What I encountered is not mentioned anywhere and I don't know if someone can help. This specific product does not accept the 802.11 protocol of our wireless network, but the 5GHz. I even reached the point of entering the password of my wireless network for the app's login and parallel synchronization with my phone, but I always received the gift of an open palm. Is there a solution?? And if so, can someone help or did I just waste my money as I suspect?? Even if I can gain something extra from its capabilities, it will be to my advantage. Thank you and be careful to those who want to buy it from abroad.
