How hotel automation works, which subsystems it covers, how it saves energy with occupancy-linked scenes, and how occupied hotels retrofit without re-cabling — explained by a China-based manufacturer.
Start a ProjectA hotel automation system is the layer that makes hotel operations run themselves: guest rooms, public areas and back-of-house equipment are monitored and controlled automatically, so routine actions (welcome scenes, energy-saving modes, housekeeping status) happen without staff walking the floors.
In practice it combines a guest room control system (RCU per room), a cloud management layer and interfaces to the hotel PMS. HOTEKEY (Guangzhou Hotekey Electronics Co., Ltd.) has delivered such systems since 2013 and is a national high-tech enterprise based in Guangzhou, China.
A HOTEKEY hotel automation project typically covers lighting, air-conditioning, motorised curtains, door locks and access, energy management and service calls — in guest rooms and extendable to public areas.
Scene-based lighting with dimming (0-10 V) and relay control in every room.
Thermostats and FCU modules; AC gateway protocol conversion for major brands.
Motorised open-close and quiet curtain tracks, wired or Zigbee.
RFID / BLE hotel locks on the same Mifare-1 one-card platform.
Occupancy-driven energy-saving scenes and per-room energy reports.
Room status, service buttons and maintenance alerts to the front desk.
The main saving comes from occupancy-linked scenes: when the room is vacant or the keycard is removed, the system switches off lighting and sets the air-conditioning back automatically — and the cloud platform turns every saved kilowatt-hour into a per-room, per-month energy report.
Because the RCU knows real occupancy (keycard, door sensor, PMS status), energy-saving scenes fire reliably instead of relying on guests to behave. The AC gateway capability lets the system control inverter and split AC units from major brands over RS-485 / Modbus.
Yes. Wireless BLE Mesh room control (J26 series) is designed exactly for this: the Zhuangduo Hotel Xintang Guangzhou project retrofitted 92 rooms with no re-cabling and opened in August 2026, and the Mehood Lestie Hotel project covered 121 rooms including voice control.
Wireless retrofits replace walls panels and add RCU nodes on the existing electrical layout, so guest rooms stay sellable floor by floor during the rollout.
Yes. Guests use scene panels, knob thermostats or the mobile interface; one action ("Read", "Sleep", "Leave") drives lighting, curtains and air-conditioning together through the RCU.
Up to 16 thermostats can be served by one RCU, so suites and connected rooms stay on the same control logic.
Yes. Front desk and engineering staff get real-time room status from the PMS link, service-call alerts and maintenance notifications, so fewer walks are needed to check a "do not disturb" or a stuck AC unit.
The Xicheng Hotel Apartment Shenzhen project runs 249 keys across 13 room types on one modular RCU architecture precisely to keep back-of-house management simple.
Send the room count, room types, target market and whether the building is new or occupied; HOTEKEY proposes the wired / wireless architecture, a bill of quantities per room type and a delivery plan through local integrator partners.
The working model is a China head office plus local system integrators — for example the Luang Prabang Wanda Meihua Hotel project in Laos — so on-site installation and after-sales stay local.
