What does a Hotekey hotel RCU project include?

Per-room RCU, floor bus, Hotekey Cloud aggregation and PMS integration, plus anti room hopping and energy-saving logic.

Can Hotekey RCU integrate with an existing hotel PMS?

Yes. Every Hotekey RCU connects to Hotekey Cloud and exposes room status, energy and fault data to major hotel PMS platforms through a standard interface.

Does Hotekey support anti room hopping for hotels?

Yes. The PMS compares card-in events across rooms; if one card drives two rooms, the RCU and PMS flag it in real time.

Mongolia Hotel RCU Project: PMS-RCU Integration & Anti Room Hopping

A overseas hotel RCU deployment by Hotekey — real-time PMS integration, energy saving and anti room hopping on every guest floor.

Start Your Hotel RCU Project

Project Background

Local project experience builds trust with Central Asia & Mongolia hotel owners

The owner's pain points

The hotel needed a guest room control system that (1) talked to its existing hotel PMS for room status and check-in/out automation, (2) prevented revenue loss from room hopping (one guest card powering two rooms), and (3) survived harsh continental climate with stable, low-maintenance wiring.

Many suppliers could ship panels, but few could guarantee a clean PMS-RCU integration with anti room hopping and local support. Hotekey delivered both hardware and the integration layer.

Hotekey RCU Solution Topology

One RCU per room, one bus per floor, one cloud for the whole hotel

How the system is wired

Per-room RCU: a Hotekey RS-485 / Modbus (or KNX) room control unit manages lighting, AC, curtain, service buttons and the door display.
Floor bus: rooms share a safe low-voltage bus back to the floor aggregator, then to the hotel network.
Hotekey Cloud: aggregates every RCU, normalises data and exposes room status, energy and alarms to the hotel PMS through a standard interface.
Anti room hopping: the PMS compares card-in events across rooms; if one card drives two rooms, RCU + PMS flag it instantly.

Results & Takeaways

PMS live room status

Housekeeping and front desk see real-time room occupancy and DND without extra hardware.

Revenue protected

Anti room hopping closed a recurring leak the previous system could not detect.

Lower energy bill

AC and lighting follow card-in / PMS schedule, cutting empty-room consumption.

Local proof

A deployed Mongolia case gives Central Asia owners a reference they can trust.
