YoLink Hubs are the gateway to the internet for your YoLink devices. As opposed to many smart home systems, the individual devices are not on your network or WiFI and are not directly connected to the internet. Instead, your devices communicate with the Hub, which connects to the internet, the cloud server and the app.

Your Hub requires a full-time internet connection. This can be provided by your WiFi and/or a direct connection to your internet/network equipment (also known as an Ethernet connection).

If using a WiFi connection, please note, like most IoT and home automation devices, your Hub connects only to the 2.4 GHz WiFi band. Nearly all residential WiFi routers have a 5 and a 2.4 GHz band. But your router may or may not display SSIDs for both bands or they may both have the same name.

If you know which SSID is your 2.4 GHz band, this is the one your Hub will connect to. With some exceptions, your router and the Hub will connect automatically via 2.4 GHz. Some routers may attempt to connect your Hub to 5 GHz. Additional setup support may be needed, for example, changing your router settings. Refer to the WiFi Considerations section for more information.

 🤔 “5 GHz” should not be confused with “5G” cell phone serviceYou can have multiple hubs, including a combination of this YoLink Hub and other YoLink hubs. While the YoLink wireless network has up to a ¼ mile open-air range, additional hubs may be required in large buildings, such as high-rises, and/or to support thousands of devices.

⚠️ Multi-step authentication WiFi networks, like hotel or airport WiFi, are not supported!

⚠️ If you experience difficulties scanning in a new device, ensure the code is not dirty or smudged, and that the camera has adequate lighting. If you are still unable to scan a device, please make a note of the serial number for our customer support staff. This is the number right below the QR code, a long number preceded by “S/N”YoLink Hub

G. Installation

You can, and you may find it more convenient to, set-up your Hub at a desk or table before placing it or installing it where it will be permanently located, but direct connection to your internet/network hardware (router, switch, satellite, etc.) via Ethernet is required for “plug, plug & play” set-up. You will connect the Hub to your internet/network equipment either using the included Ethernet patch cord, or another Ethernet cord.

And it is also worth considering that for larger homes and buildings, and/or if you will have devices outside of your home, it’s possible you may need to relocate the Hub to an optimal location, in order to cover your entire home, building or property. And should one Hub not be sufficient, you can add as many hubs as you want, later, to extended the coverage of the YoLink wireless network.

The Hub is USB-powered and it will require a dedicated AC outlet for the included USB power adapter, or it can be plugged directly into a compatible USB outlet.
The Hub does not have an internal battery, it must be constantly plugged into a suitable source of power, as noted above.
You may consider powering your internet/network equipment and the Hub from a UPS back-up power supply, with the purpose of maintaining full functionality in the event of a power outage and loss of internet connection. And, consider the use of our Control-D2D device-to-device pairing feature, which is outlined in the product user guides. Paired devices can work even with the loss of power and internet (battery-powered or backed-up devices, only).
Your hub is intended to be installed indoors, and kept clean and dry.
Do not place your Hub near sources of heat, like a space heater, as well as intense direct sunlight, either of which can damage the Hub.
Avoid placing your Hub inside, on or near metal, or sources of radio or electromagnetic energy or interference. Avoid placing your Hub under or on top of your WiFi router, satellites or any such RF signals transmission sources.

H. Connections & Power Up 

Diagram of usb cable, power jack, and hub

1. As shown, power up the Hub by connecting one end the USB cable (A) to the power jack (B) on the Hub, and the other end to the power adapter (C), plugged into an outlet

2. The green power indicator should flash:

Left most button (PWR) should be flashing green

3. It is recommended that you connect your Hub to the network/internet even if WiFi-Only is your intended format. Using the supplied Ethernet patch cord (D), connect one end (E) to the Hub, and the other end (F) to an open port on your router or switch. The blue Internet indicator should turn on:

Middle button (Internet) indicator should turn blue

4. In the app, the Hub is now shown to be Online, with the Ethernet icon green as shown

5. If you plan to connect your Hub to the internet via the Ethernet cable, only, and your Hub is online, proceed to section L, to complete the setup of your Hub.

⚠️ If your Hub is NOT Online after this step, please double-check your cable connections. Check LED indicators on the Ethernet jack on your Hub (refer to section D). There should be similar LED activity on your router or switch (refer to your router/switch documentation)

I. WiFi Considerations

Your Hub connects to the cloud via an Ethernet and/or WiFi connection. If an Ethernet connection is available, we recommend using it, and this is the “Plug, Plug & Play” method that will result in the easiest and fastest setup of your Hub. There are additional considerations, specific to using a WiFi connection with your Hub:

  • Changes to your internet provider, internet equipment may require updating the WiFi-related settings in the YoLink app again.
  • Changing your WiFi passwords or SSID name will require updating the WiFi-related settings in the YoLink app again

A WiFi connection, if optional, may not be ideal for you if:

  • Your WiFi is not dependable or stable.
  • You are not the owner/administrator of the network/WiFi.
  • You’ve forgotten or do not have the WiFi password.
  • Your WiFi has a second verification process or additional security.You’d rather not share your WiFi credentials with additional apps.

🤔 If you have a mesh and/or WiFi 6 type network, like a Google Nest, TP-Link Mesh, or Eero, you will most likely need to disable the 5GHz WiFi band while connecting your Hub. Helpful information can be found on the Hub’s product support page, or contact our customer support department. If your network requires opening ports or white-listing MAC addresses, helpful information can be found on the Hub’s product support page.

J. Mobile Device Settings

1. iOS phones only: if prompted, enable Local Network Access. (Search “iOS location services” for more information)

2. If prompted, grant access to your location. Tap Allow Once. This is required for the next steps.

To check or edit Location Services on your phone:


iOS icons of Setting to Privacy to Location Services

Go to Settings, tap Privacy, tap Location Services.

Ensure Location Services is on/enabled.

Scroll down to and tap the YoLink app.

Select While Using the App

Enable Precise Location


Android icons of settings to location

Go to Settings, tap Location. 

Ensure Location is On.

Tap App Permissions. Scroll down to and tap the YoLink app, then set permission to Allowed Only When in Use. 

Ensure you are logged into your WiFi:

1. In your phone, open WiFi settings (Settings, WiFi).

2. Identify your 2.4 GHz network, if possible. If there is only one SSID (network ID) you recognize, you will use that one.

3. Select the appropriate network and log-in, if needed.

4. If your SSID is hidden, you must manually log into it on your phone, by selecting “Other...” in Other Networks or Choose a Network

🤔 Some routers allow you to "white list" a device based on its MAC address. The MAC address for the Wireless LAN Driver can be determined by combining "D88B4C" with the last six digits of the EUI number. The MAC address for the Ethernet LAN Driver can be determined by combining "D88B4CFF/D88B4CFE" with the last four digits of the EUI number. The EUI number can be found on the device details screen.

K. WiFi Set-Up

1. If you are able to, but have not already provided your Hub with an ethernet connection, as explained in the Connections & Power-Up section, do so at this time.

2. In the app, from the Rooms or Favorites screen, tap the YoLink Hub icon.

3. Refer to WiFi icon, it should read “Not Connected” – tap this icon.

O. Adding Devices

Your Hub will be awfully lonely without some devices, like smart locks, light switches, water leak sensors or sirens to interact with. Now is the time to add your devices). You already know how to do this, because you added your Hub to the app; it is the same process of scanning the QR code that is on each device. Look again at part F for a refresher.

1. For each new device, refer to the instructions in the quick start guide* packaged with each product. It directs you to download the full Installation & User Guide, using the QR code in the "QSG". Refer to the full manual, and when directed, scan the device's QR code to add it to your system.

🤔 The quick start guide, or QSG, is a small and basic set of instructions that are packaged with each product. The QSG is NOT intended to guide you through the entire installation and user guide process, but it is only meant to be an overview. The full manual is too large to be included, plus, while the QSGs may be printed in advance, the manuals are always kept current with the latest updates to your products and app. Please always download the full Installation Manual & User Guide, to ensure the smoothest installation.

2. When directed in the manual, turn on your device (typically by pressing the SET button).

3. Always confirm your device is online in the app before proceeding to the next device. Refer to Figure 1, for an example of of online and offline devices.

P. Factory Reset

Factory reset will erase device settings and restore it to factory default settings. Doing a factory reset will not remove the device from your account and it will not harm the device, or lose any data or require you to redo your automations, etc.

Instructions: Hold the SET button down for 20-30 seconds, until the LED blinks red and green alternately. Then, release the button. (Holding the button down longer than 30 seconds will abort the factory reset operation)

Factory reset will be complete when the LED stops blinking

🤔 Only deleting a device from the app will remove it from your account. Factory reset will not delete the device from the app.

Q. Firmware Update

Your YoLink products are constantly being improved, with new features added. It is periodically necessary to make changes to your device's firmware. For optimal performance of your system, and to give you access to all available features for your devices, these firmware updates should be installed when they become available.

In the Detail screen of each device, at the bottom, you will see the Firmware section, as shown in the image below. A firmware update is available for your device if it says "#### ready now"

Tap in this area to start the update.

The device will update automatically, indicating progress by percentage-complete. You may use your device during the update, as the update is performed "in the background". The LED will slowly blink green during the update, and the update may continue for several minutes beyond the LED turning off.

S. Troubleshooting

Hub (Ethernet) is offline

Possible Solution

1. Check the LED behavior on the hub. If the LED blinks green, blue, and red alternately, the hub is in ATE mode. Repower the hub without pressing and holding the SET button during the process.

2. If the green LED is dimly blinking, try using another USB adapter and USB cable. Do not plug the USB cable into a USB extension cable, as it may reduce the power supply, causing the hub to malfunction.

3. If the LED blinks green only, check the Ethernet jack's LED lights. The yellow LED should blink, and the green LED should remain on

If the Ethernet LEDs do not work:

1. Try using a different Ethernet cable (RJ45).

2. If the Ethernet LEDs work properly, try another router port.

3. If the issue persists, restart your router.

4. If the issue still persists, whitelist the MAC address of the hub on your router's configuration page.

5. If none of the above steps resolve the problem, please contact YoLink Customer Support (see the contact info on the last page of this guide)

Hub (WiFi) is offline

Possible Solution:

1. Check the LED behavior on the hub. If the LED blinks green, blue, and red alternately, the hub is in ATE mode. Repower the hub without pressing and holding the SET button during the process.

2. If the green LED is dimly blinking, try using another USB adapter and USB cable. Do not plug the USB cable into a USB extension cable, as it may reduce the power supply, causing the hub to malfunction.

3. If the LED blinks green only, follow these instructions based on your hub's firmware version (you can view the firmware version in the Device Details screen):

For firmware 032X: Temporarily connect the hub via Ethernet, then go to the YoLink app > tap to select your hub > tap the Wi-Fi icon in the upper right corner, input your SSID and password, then unplug the Ethernet cable. If you're using a 2.4GHz Wi-Fi band, make sure your phone is connected to the 2.4GHz band before entering the password.

For firmware 035X or newer: Use the hotspot configuration method as instructed by the app. If you encounter a "Connect to device timeout" error, tap Close, pull down the notification panel on your phone, and select the notification about no internet access. Tap "Yes" to stay connected to the hotspot and continue. Alternatively, you can temporarily connect the hub via Ethernet and input the SSID and password on the Wi-Fi configuration page in the app.

If you're using a mesh network, search for a solution to temporarily disable the 5GHz band on your router forum or contact YoLink with your router brand and model for assistance. Temporarily disabling 5GHz will not disconnect your other devices.

Please ensure that you follow these troubleshooting steps and instructions for the proper connection of your YoLink Hub to Wi-Fi.
