The technical department reported that this device could not be added. Please confirm whether the original remote control of J: COM LINK is controlled by infrared or Bluetooth. If it is infrared control, it is recommended that you add this device separately through the learning function after updating the app and firmware. For Bluetooth control devices, please refer to the following steps: Add Bluetooth device: first, add the corresponding Bluetooth device in the APP (if you can't find your device, you can try to select ''other''), then use the original remote control to control your device, enter the Bluetooth search menu, find the SofaBaton X1, and then click Connect. We updated the firmware of APP, HUB, and Remote on April 11th and fixed some bugs. Please download the latest APP version V3.1.8 and upgrade the firmware.
