Chess and Mahjong Room Operations and Device Linkage Solution

The solution uses the free and open-source RoomCtr local management system as the operating core, then combines Zhenming network relay controllers and optional energy acquisition to connect room opening, billing, members, payments, lighting, air-conditioning, main power, reports and audit logs.

Four Core Capabilities

Room OperationsRoom states, opening, pause, extension, settlement and cleaning reminders.

Billing and MembersFlexible billing, multiple payments, balances, points and member pricing.

Room Device LinkageLighting, AC and main-power channels follow start-room and settlement events.

Local and TraceableLocal database, backups, reports, exports, permissions and operation logs.

Application Overview

Connect business events with field equipment

A room-opening action creates the order and activates configured equipment. During use, the operator can pause, extend or adjust the order. Settlement completes the payment record and runs the configured room shutdown action. Reports and logs retain the business and operation trail.
