Support Xenocam A1TT via G2 Gateway (Bluetooth)

Currently, the Xenocam A1TT smartlock only reports status and battery levels in Hospitable when connected via direct Wi-Fi. However, many users prefer using the G2 gateway (Bluetooth-to-gateway) to save energy. We need Hospitable to support this connection method so that the lock status and battery levels sync correctly without requiring a direct Wi-Fi connection.
