The SK-RCU18P is a modular Guest Room Control Unit (RCU) independently developed by Dingshengwei. It enables intelligent control of air conditioning, lighting, curtains, room occupancy sensing, and other in-room devices, while supporting energy management and customized scene modes. The system can be managed through both local and cloud servers, allowing remote control, firmware upgrades, debugging, configuration, and centralized management of front-end smart devices. Through intelligent energy management, the SK-RCU18P helps reduce carbon emissions and operating costs. Its smart control capabilities also enable hotels to provide guests with a more personalized, comfortable, and efficient in-room experience.

The SK-CP021 Card-Operated Power Switch utilizes high-frequency 13.56MHz Radio Frequency Identification(RFID) technology. It supports an RS485 communication interface and dry contact output. It works in conjunction with the Room Control Unit (RCU) to manage power usage within the guest room.
