Dear Customer, Thanks for your reaching out. There is something misunderstanding on my side，I do apologize，now all the firmware and hub are under test stage. As far as I know，it will be updated successfully before mid of December at latest or at fast at the end of November，the screen-shooting I attached is from our test engineer's phone. They have updated to the latest update one for testing each and find any bugs or not. I will keep you posted while ready to publish，thanks for your understanding.OωO

Your device has been added to our database.Pls try to re-add it via searching Brand：Harman Model： Kardon AVR-1600.

Sorry for the inconvenience The macro key can control multiple devices. In reality, one key is directly accessible, but the macro only supports infrared devices and does not support Bluetooth devices. The key assignment changes the device to achieve different inputs.

Thank you for your suggestions. I will feed back to our engineers. API functions are already available. You can download the latest application in the APP Store to use it.

Please plug the hub into the power supply before the remote control can synchronize with the hub. If it still doesn't work, let the hub complete the setup of the new hub, and then restart pairing in me -- x1 settings pair with a new X1 Remote. If it still doesn't work, you can send the failure video and your Amazon account to our mailbox，SofaBaton@outlook.com.

Pls exit(kill) the app at first, and then open the app, when you are updating the firmware of the remote, pls wake up the remote and brighten its screen Then check if it could update successfully or not. FYI, When upgrading, please put the hub and the remote together to avoid too far to upgrade. too slow to fail.

Thank you for your sharing, and we will continue to optimize our equipment,tks.

Recently, we are testing the new version, which is expected to be released in late November or early December. Thank you for your patience.

Would you please tell the Specific Model of your device? thanks :) such as: Brand:LG Model: 60UF7300 Because the remote control of each device is different, knowing the specific model of your device, we can better test and solve the problem. If the database is not complete, we can update it for better use.Could you send it to our email address?SofaBaton@outlook.com.

You can create an Activity to realize the mutual linkage between multiple devices. Activity supports the creation of multi device scene linkage (games, cinemas, etc.), which is controlled by one button through the remote control. I send you a video, hoping it can help you，https://www.youtube.com/watch?v=TFUja-P0TAM
