Friday 9th August 2025. All of the sudden, with no apparent reason, my so-far-perfectly-working Samsung soundbar HW-Q800D has disappeared from Smarthings. The WiFi and Bluetooth don´t work anymore. The WiFi status remains disconnected full time. Also the bluetooth. The device is undetectable. The bluetooth pair remote button doesn´t work either. Firmware update via USB hasn´t worked. Factory reset neither. Unplug and re plug the main power neither.
