Management Functions

Room Console: Centrally monitors basic room information (room number, status, type, AC mode, service info, messages), main unit status, and other devices; enables remote control.

Control Overview: Real-time status check of each RCU, including lights and AC.

Room Type Management: Create and edit room types, manage floor plans and device naming, configure the smart control panel interface.

Room Management: Manage room creation, grouping, and centralized control of bound devices.

Guest Room Management: Batch processing of room parameter settings (mainboard, room type, IP/MAC address, etc.); configure room status, keycard delay, seasonal mode, etc. Supports import/export. Real-time device control based on room type. Preset AC modes based on room status, set scene modes by room type, and assign them to specific rooms.

Doorplate Management: Manage doorplate devices, support import/export, batch upgrades, and upgrade package management. Supports custom doorplates, setting display content, recognition duration, and volume. Register guest info, view information and door opening records.

Media Asset Management: Upload and manage multimedia resources with flexible storage path adjustment.

System Configuration: Supports cloud data backup. View energy consumption analysis, operation logs, service events, RCU online/offline logs, RS485 device online/offline logs. Configure whether the doorplate captures an image when someone rings the bell and displays a prompt on the in-room TV or smart control panel. Features include host search function, control restoration package management, and linked device settings.
