Thank you for contacting us regarding Alexa's inability to synchronize Check two points first to ensure there are no issues 1. Alexa can only synchronize Activities, not Devices Please ensure that the activity has been created 2. The account used for Alexa's account linking needs to be the same as the Sofabatonapp account. The account used when setting up a new hub. If there are still problems, they can be investigated and handled through the following methods 3. First open the sofabaton app, Me - API interface, turn on the switch, and check if there is an API link corresponding to the activity. 1) If there is a link and it is online, it indicates that there is no problem with the device networking. It is an Alexa synchronization exception. Open the Alexa app, disable skill first, then click Enable again, and repeat the account linking to see if it is OK after the update 2) If the information in the API is blank and there is no link, it indicates that the Hub is not connected to the internet or the login to the cloud account is abnormal. Please use your current account to complete the setup new hub process again and have the hub reconnect to WiFi to ensure verification is successful. This process will not affect the devices and activities that have already been added, but will only allow the hub to log back in to the cloud, facilitating the synchronization of activities information to the cloud After the API check synchronization is successful, go to Alexa to discover scenes

There are several reasons why devices may not turn on or off properly. You'll need to follow the corresponding steps based on the specific issue. CEC function causing confusion: Disable the device's CEC or similar function. CEC may conflict with activity operations, causing issues with turning devices on and off. Incorrect power state: Press the Off button on the remote control to close all activities. If any devices are still on, manually turn them off (always use the remote control or X1 to switch to device mode to turn off the device). Ensure that the power state of the devices matches what is recorded in the activities. Then, reopen the activities, and things should return to normal. Incorrect power key in the code library: On the device control page in the app, click on the "..." icon and review the command list. Test the power button to see if it works. If the power key works, it means there is no problem with the power key. Look for other solutions. If the power key doesn't work, repair the command. Wrong power setting: On the device control page in the app, click on the virtual power button to manually confirm if it works. If the power button works, it means there is no problem with the power setting. If the power button doesn't work, check if the power state and power command are set correctly in Edit > Power Settings. Refer to the article on Power Settings or the video tutorial for help.

Thank you for contacting us We suspect that the inconsistency between the device status and the record in the activity is causing it. We suggest the following: 1. Press the remote control to turn off all activities. If any devices are not turned off, please manually turn them off. Make all device states consistent with the activity. Then open the activity again to see if it is working properly. 2.Sometimes CEC may also cause device switch status conflicts. It is recommended to turn off the CEC function of the TV. Avoid sending commands to the TV through HDMI when other devices are turned on/off, as this may duplicate activity commands and result in abnormal control

Sorry for the inconvenience caused to you Please check if the TV has turned on the CEC function, and if so, please turn it off. This may be a functional conflict
