Very good for Xiaomi devices. I have connected many devices and it works perfectly. It notifies you if it loses connection or is generally offline (e.g. power outage).

If you want to connect ZigBee or Bluetooth devices to Xiaomi Home, this is the only solution. It only connects Xiaomi Mi devices, not Aqara or IKEA.

Currently, there is the 2nd version, so it's better to get the newer version.

I would give it 4-5 stars for as long as it worked, but my experience with it lasted less than 24 hours. The same night I bought it, it stopped working, as it now only turns on a yellow light that turns blue after a few seconds but does nothing else. It no longer connects to the internet, doesn't connect to my phone, doesn't connect to Xiaomi thermometers, and can't be reset even with a 10-second long press or 10 taps that theoretically only reset the WiFi. It practically does nothing, it's either for return or throwing away. I will get another BLE gateway, but definitely not Xiaomi.

Average, construction quality is decreasing, I had to buy 2 in order to connect the xiaomi buttons and xiaomi sensors. It connects very easily and quickly. Its range is relatively ok. The response to the sensors and buttons is fast as long as they are at a good distance from the hub

It connects with Bridge cameras, etc. but it does not perform automations, you need to get another hub where the app will recognize it, if it is compatible if it is in China Singapore area... it still needs work

4 stars because when there is a power outage, it loses the devices and you have to reset them one by one for them to work properly... The problem was solved as soon as I put it on the UPS.

Generally, through Xiaomi Home, automations either don't work often or are very slow due to Xiaomi servers, which is why I gave it 4 stars. Now I use it for Home Assistant as a Zigbee adapter through ZHA with AlexxIT's integration on GitHub, and it has also been tested as a zigbee2mqtt adapter with AlexxIT's integration. I have 13 connected zigbee devices, and it also controls supported Bluetooth devices, such as the Mi Temperature and Humidity Monitor 2. It is quite reliable, as long as the 2.4GHz channel on WiFi is not congested. I had tried the SONOFF CC2531 and it was terrible, with a small range of only 5-6 devices and frequent restarts.

Connected with 8 door/window sensors, 4 motion sensors, and 2 thermometers. Works flawlessly, without any disconnections. With the Aqara m1s hub, set up to connect to the mi home app, I have more options for notifications and alarms in terms of sound. Perfect.

For anyone struggling to connect the device to wifi. After 3 days of trying with various wifi access points, changing names and mobiles, I realized that the smart hub fails to connect if you have disabled tkip in the wifi settings.

For the past 3 days, I haven't been able to connect it to the application. It shows that it detects the wireless network but it doesn't proceed to the 3rd stage of the connection with the mi home application. In the end, it was the router's fault. With a change, it connected directly!

Reading the reviews and comments about disconnects, I want to share my experience because I believe it will help some people.

The hub connected instantly and very easily with the devices, and for now it is connected to 14 Bluetooth devices and works flawlessly. In some instances, I also noticed some disconnects, and after many tests (power supply strength, interference from the router, etc.), I found that if the bandwidth of the line is occupied by other services (downloading/streaming) and there is no available bandwidth, it can lead to disconnects because the hub cannot communicate with the Xiaomi cloud.

For those who experience disconnects, check if something like this is causing it.

Although it is mentioned as compatible with HomeKit, it is not clear anywhere which child devices it supports in Apple's home. The reality is that it only displays Zigbee devices in HomeKit and not Bluetooth devices. As a result, Bluetooth devices only work through the Xiaomi application. However, the response is immediate and without problems for Zigbee devices (Xiaomi door and window, motion sensors, wireless switch). If it stated that it is only compatible with HomeKit for Zigbee devices, I would give it a 5/5, but because I spent and learned, I rate it 3/5

You will find it incredibly difficult to connect the hub to the network - and when you finally manage to do it after about 30 attempts and go to sleep peacefully, you will wake up the next morning and it will have disconnected - there are many complaints online - unfortunately, I hadn't read them before buying it - stay away from Xiaomi in this particular category of gadgets

I bought it to connect some other Xiaomi accessories that I have purchased (smart plug, thermometers, etc.). Although I already changed it once, thinking that I was unlucky with the initial Hub, ultimately the second Hub continued to disconnect repeatedly and WITHOUT reason. To save my mental peace, I eventually returned it. Stay away.....

It works fine for me so far, it doesn't disconnect like some people claim. I don't know, maybe I was lucky. It does the job for its price. I have many peripherals from Xiaomi, so it's perfect. I recommend it if you are a fan of Xiaomi.

It works fine, without any problems with the door sensors. Since I had plugs and cameras before, I don't understand how they are connected to the hub. I mean, in the mi home app, the cameras and plugs were already there, and everything works fine, but do I need to do something like reinstalling from scratch so that everything works through the Hub?

In a few words..
1 star because it is one of the very few Xiaomi products that I would not want to belong to the brand.
Many disconnections.
I bought it to replace a Chinese kit. I wanted to transfer the traps to go to a European server but it's not worth it.

For those who have similar concerns, try checking out the app in the video description of a well-known video platform ("you tube" ;) )
With the title "region free mihome - unlocked app!"
Simply, the reliability of the application is a small risk if you want to get it since it is not the official application.

Small in size. Does exactly what it describes. Very easy to connect all your devices. The package does not include a charger. Only a cable.

It works correctly, it has never crashed after several months of use, and it connects to Bluetooth thermometers on two floors up and down. Although I don't particularly like Xiaomi's ecosystem that forces you to use only mobile apps, you can do a great job with the scenarios and automation. Absolutely no complaints.

A great device. I don't know much about what I read, that devices don't connect, that it's slow with notifications, but what I have to say is that it works perfectly for me without any issues, all notifications come through instantly. It doesn't freeze, doesn't turn off, doesn't disconnect, I have it next to the router and it's perfect. It has plenty of accessories to purchase along with the hub, so you won't miss out on any functions that most people want. Just keep in mind that only Xiaomi and Aqara products can be connected to the Xiaomi hub, it doesn't recognize the others

I connected all the devices I had to the Aquara hub, the only thing that doesn't connect is Aquara bulbs. Body Sensor, cameras, temp sensors, switch, and everything else I had, it picked up. (I selected them as Xiaomi and not the Aquara ones that were actually there). Also, I'm using it with Google Home Assistant without any issues for now. Satisfied with its value for money.

The notifications sent to the mobile arrive after an hour. Do not buy anything from the mi home series, they do not work properly.

It has a very weak sound and no option for sound selection. It has that classic annoying "beep beep" and the automations react quite slowly and sometimes not at all... Nevertheless, it functions relatively well, it doesn't disconnect, and it has good range between connected devices. A mediocre product

It works perfectly after 2 months. I also bought a second one and connected it to the Aqara water leak sensor! Although I couldn't connect the Aqara water leak sensor to the new Xiaomi YTC4044GL Smart Home Hub through the Mi Home App, I finally managed to do it by pressing the mi hub three times (activating the search for a new device) and then long-clicking on the water leak sensor for 5 seconds, which automatically pairs the devices and the sensor finally appears in the Mi Home App! Luckily, I didn't need to buy an additional Aqara Hub!

I bought it to connect humidity and temperature sensors to HomeKit. And a wireless switch. It's good, but sometimes it doesn't catch the switch click on the first try. Also, the devices that can be connected to it are limited in variety.

The 1 star is lost for the sounds and the fact that it is not compatible with Google Assistant. It is worth its money, it does everything that its predecessors did and it has not given me any issues with disconnections, neither with the wifi nor with the connected devices (bluetooth & zigbee). It is worth it to create any automations you have in mind. Not even for a security system

I have had it for a long time and I had disconnections every day, I put it in a voltage stabilizer and I calmed down. I have 25 devices on it.

Very easy to install.
It was mainly purchased to connect several Xiaomi temperature & humidity monitors 2 via Bluetooth.
They were immediately recognized and work perfectly through the Xiaomi Home application.
It also immediately recognized a Zigbee door sensor.
Unfortunately, these devices are not connected either to Homekit or to Google Home.
