The steps on the PC side are as follows:
1. Click the network icon in the bottom right corner of the system desktop.
2. Click [Network and Internet Settings] in the pop-up box.
3. Click WLAN on the left-hand side.
4. Click [Hardware Properties] under [WLAN].
5. Then you will see information about network band.

Android：
Different brands of Android phones are different. Take Huawei mobile phone as an example. You can click on the connected Wi-Fi name in the Wi-Fi list, and the corresponding information will be displayed, including the frequency.

iOS：
1. Download the AirPort tool in the App Store
2. Turn on the Wi-Fi Scanner in ""Settings - Airport Tools""
3. Open the App and click on “Wi-Fi Scan” in the upper right corner. Channel 1-13 band is 2.4G, and larger than 13 is 5G.
Note: How to configure separate Wi-Fi SSIDs for 2.4 GHz and 5 GHz bands?

Step1: Put device into Pairing ModeLong press the menu button for 5 secs to factory reset the device or long press the two navigation buttons for 5 secs to rest the Wi-Fi. The Wi-Fi indicator flashes to indicate that the device is ready to pair.

Step2: Tap""+""button on App to add deviceOn the ""Add Device"" page, select the category of the device and select the Wi-Fi type.

Step3: Connect device to home networkSelect a 2.4Ghz Wi-Fi at home and enter the Wi-Fi password to connect the device to the network.
Wait for 2 minutes, and the device will be added.

If the device pairing failsYou can retry as follows：
1. Reset the device and reconfigure the network. See the first step for the reset operation.
2. Move the device close to the Wi-Fi router to connect the network.
3. Confirm whether the Wi-Fi type is 2.4G. If it is 5G Wi-Fi, you need to switch the Wi-Fi to 2.4G.

Please troubleshoot in the following ways:

1. Please check whether the device is normally powered on or whether the battery has sufficient power. The device may have been powered off for possible reasons.
2. Please check whether the Bluetooth of the mobile phone is turned on. The Android mobile phone must also open the location permission of the App, otherwise the Bluetooth device in the App will be offline.
3. Whether the mobile phone is too far away from the Bluetooth device. If the mobile phone is directly connected to the Bluetooth device without using the Bluetooth gateway, the distance should not exceed 3 meters.
4. Another person has logged into your App account to control the Bluetooth device. Without using the Bluetooth gateway, the Bluetooth device cannot be shared and can only be controlled by one mobile phone. For example, two mobile phones log into the same App account. When one mobile phone is controlling the device, the app of the other mobile phone will show that the Bluetooth device is offline.
5. The device is too far away from the Bluetooth gateway or the gateway is offline. When the gateway is connected, the distance between the Bluetooth gateway and the Bluetooth device should not exceed 3 meters.
6. Check whether the firmware is the latest version, the App side check path: Home page—click the device icon—click the upper right button-check for updates.

If your device is offline for a long time, you can only manually reset the device to pairing mode, and then manually add the device again. The function of remotely resetting the device is not supported.

If your device is offline for a long time, you can only manually reset the device to pairing mode, and then manually add the device again. If your device is always offline, please check the following:
1. Check whether the router is powered off or disconnected from the network. If so, the router will take some time to recover. Wait for two minutes and then check whether your device is online.
2. Check whether the router has been replaced, or the Wi-Fi name or password has been changed. If so, remove your device and then add it to the network again.
3. Please confirm whether the device has just updated the firmware. The device will be disconnected from the network when the firmware is updated, and will automatically connect to the network after the update is completed. However, if your network is unstable, it will appear that you cannot connect after the firmware update is complete. The device needs to be removed and added again.
4. The Wi-Fi signal of the device is too poor (for example: there are several walls separated from the router; the device is surrounded by a metal shell or there are metal objects nearby; nearby high-power appliances such as air conditioners and refrigerators interfere).
5. The location of the device is too far away from the router. Ensure that your device is not more than 10 meters away from the router to ensure stable connection.
6. Check whether the firmware is the latest version. To check this on the App, choose Home—tap device icon—click the top right button—go to Device Info—check for device update.
7. If the device goes offline after a period of use but returns to normal after restarting the router, it indicates that the router is overloaded. You need to replace it with a more powerful one or reduce the number of devices connected to the router. Due to the low bandwidth characteristics of the 2.4 GHz network, it is easy to go offline when there are more than 7 online devices on the 2.4 GHz network.
8. You can also use a phone hotspot to check whether there is a problem with the network.
If your device still fails to connect to the network after the preceding steps, place your device in a network environment with strong and stable signals and connect it to the network again.
If your device still fails to connect to the network after the preceding steps, place your device in a network environment with strong and stable signals and connect it to the network again.
If your device or its indicator light keeps flashing for no reason, please troubleshoot as follows:
1. Please confirm whether you have removed the device from the App. Some devices will automatically enter pairing mode after being deleted. If the device or device indicator flashes continuously, it means that the device has entered pairing mode.
2. Please confirm whether you have frequently opened and closed the device in a short period of time, or accidentally long-pressed the power button of the device. Due to the operations above, some devices will be reset to pairing mode, which causes the device or device indicator flashing constantly.

Firstly, you need to make sure that you are connected to a 2.4GHz network. If you are not sure what your network is, you can follow this:If your router supports both the 2.4 GHz and 5 GHz bands, but only one Wi-Fi name is displayed on the Wi-Fi search page of your mobile phone, perform these steps:

1. Go to the wireless page of the router. (The entry address is usually provided on the label attached to the back of the router).
2. Go to the 2.4 GHz setting page, and set the Wi-Fi name (SSID) to XXX—2.4G, where xxx indicates the Wi-Fi name. Save setting.
3. Go to the 5 GHz setting page, and set the Wi-Fi name (SSID) to XXX—5G, where xxx indicates the Wi-Fi name. Save setting.When the preceding settings are complete, the new Wi-Fi names will appear on the Wi-Fi settings page of your mobile phone.

Note: After the Wi-Fi names are changed, you need to reconnect the devices that use this wireless router. The password remains the same if it has not been changed.It is recommended that you use the AP mode (the AP mode will automatically select the 2.4GHz network for connection), and then add it again. If you can connect to the device but have problems, you can provide us with the device ID. Thank you for your understanding and support!

Please check the following:
1. Pairing a Bluetooth device needs to be added in our App, not the Bluetooth-adding interface of the phone.
2. Make sure the Wi-Fi switch of your phone is on, and the router is working normally.
3. Your iPhone must be connected to the network when paring a Bluetooth device (because the Bluetooth device needs to be registered on the cloud server to be added successfully).
4. If you use an Android phone, you must open the App's location permission.
5. The device may have been added. It is recommended to reset the Bluetooth device and add it again.
6. Whether the distance between the Bluetooth gateway and the Bluetooth device is moderate (less than 3 meters), it is recommended to be as close as possible (if there is no Bluetooth gateway, you can skip it, just connect to the phone directly).
7. Check whether there are other users around using the Bluetooth device (the Bluetooth device can only be controlled and used by one user at the same time due to its characteristics, and it will be offline when other users are using it).
8. The Bluetooth device you added is not our product. Bluetooth devices have certain private protocols, so other brands of Bluetooth devices cannot be added to our App (even if they are added successfully, they cannot be controlled)."
