YoLink Hub

  • Question: Why I cannot connect the hub to WIFI?


First, YoLink Hub only supports 2.4 GHz WIFI, it does not support 5.0 GHz WIFI, you will need to switch to 2.4G SSID.

You can refer to the following video for WIFI connection guide https://youtu.be/2ibCmgKW9yA

Second, do you have a wired ethernet connection in your home? You can connect YoLink Hub to your wired internet cable.

When the middle blue light shows solid blue, it means the Hub goes online. The WiFi can be set after the Hub goes online with the internet cable.


  • Question: after couple of days testing the set up, the hub dropped the connection three times


Please kindly confirm the using environment of your network. Are there any restrictions? Is there a network administrator? How does it work in normal use?

Any question, please kindly contact us at email service@yosmart.com.


  • Question: why i cannot conect my hub to the internet?


Could you please kindly confirm the following information?

1, When the YoLink Hub is connected to the router port through a network cable, does the indicator light at the network port of YoLink Hub work normally (green light is always on, yellow light is flashing)?

2, If the green light is always on, yellow light is flashing, please kindly power off the YoLink Hub, and re-connect it to the power and the router. After re-start, does the YoLink Hub connect to the internet?

Any question, please kindly contact us at email service@yosmart.com.


  • Question: How many sensors could one hub accommodate?


One YoLink Hub supports 200 YoLink devices in real test.

And you can add one or more YoLink Hub to expand signal coverage.


  • Question: Can I have more than one hub per account?


Yes, you can have one or more YoLink Hub in one account. Each hub must be configured with a network (wired/2.4G WiFi).

And with multiple hubs, you can easily manage devices in multiple locations on the same YoLink APP account.


  • Question: Can i use other manufacturer zigbee sensors or devices on the hub? Or Will the yolink sensors connect to another lora gateway?


YoLink is based on LoRa and YoSmart, it is an independent smart home system. YoLink Hub is the only central controller gateway for the rest of YoLink devices.

YoLink Hub does not work with other brands of sensors, and YoLink devices cannot be used with other brands of gateways.

We will support API connection, which can make other platforms compatible with YoLink series products.


  • Question: I just purchased a YoLink Hub. I am out of Ethernet ports. What kind of splitter adaptor to I need to connect the device? Will a simple cable splitter work or do I need a Network Switch?


Any splitter can work, or you can use the 2.4G WiFi connection for the Hub. Check the following link for the splitter from Amazon https://www.amazon.com/dp/B00A128S24


  • Question: Does the YoLink Hub has MAC address?


YoLink Hub has a MAC address. You can find the Device EUI of your YoLink Hub within your YoLink APP account, remove the number 1603, you will get the final Mac address of your YoLink Hub.

For example, the device EUI of one YoLink Hub d88b4c1603000011. You need to remove the number 1603 from the EUI. Then the mac address for this YoLink Hub will be d88b4c000011. 


  • Question:…EVERY sensor was offline…


Relating to YoLink Smart sensors offline, please do not worry, they are functional.
Among YoLink devices, the YoLink Hub is the only one connects to internet. The rest of devices automatically connect to the hub by kind of “Shaking Hands”.

In order to save energy, the smart sensors only send signals to hub once a while(for different sensors, the spacing interval is different. for example, it is every 4 hours the water leak sensor sends signal to the hub; for smart plugs, it will report data in every 30 minutes), as they don’t detect any status changing.

But once they detect anything happening, they immediately send the signals to the hub.

The reality is YoLink sensors and plugs don’t need and never directly connect to internet. That is why some YoLink devices can work and have automation even without internet once they are set up by Yolink control.

The reason that it shows “offline” is only meant to remind you that the hub doesn’t connect with the internet now or before.

If you don’t like that it displays offline as it may be confusing, please press the set button on the device once, and then the Offline text will be gone, it will change the status and be online immediately.


  • Question: What will happen when my daughter turns off the hub?


First, you need to charge the YoLink Hub using the supplied power adapter to the power outlet; and you need connect the hub to the router by Wired or 2.4G Wi-Fi connection.
Second, if the hub is powered off or loss the internet connection, the YoLink Hub will display “OFFLINE” in YoLink APP. And the YoLink App will push the hub is offline message
Third, when the hub is offline, you cannot use YoLink APP to control or monitor other YoLink Devices, and you will not receive notifications.


  • Question: What port(s) does this device use? My firewall is blocking it from connecting to the outside world. Is this device unable to function on LAN only? Not sure why it’s necessary to connect to WAN and send my personal info to your servers…


First, the port is 80/443(HTTP); 8001(TCP)

Second, the YoLink Hub needs a network (WAN) to work properly; and the local area network (LAN) cannot work properly.
The functions of APP remote control, Alexa/Google Assistant/IFTTT Integration, YoLink APP Notification, Email Notification, SMS Notification are all based on the network.
Except for account registration, we do not collect other private information of users. The hub is only based on WAN transmission and encrypted device communication data.
