Modern professional Curtain Smart Switch platforms typically offer open API interfaces, which serve as the technical foundation for integration:
① Integration with PMS (Property Management System)
Via API, the PMS can sync real-time room status (e.g., vacant, occupied, checkout pending cleaning, DND mode) with the curtain control system. The system then executes tailored strategies, such as:
- Vacant rooms: Enforce “deep energy-saving” mode (curtains closed, wider thermostat range).
- Guest check-in: Switch to “comfort mode”, activating standard automation based on light/temperature.
- DND mode: Pause automated adjustments to respect guest privacy.
② Integration with BMS (Building Management System)
This enables bidirectional data exchange for smarter operations:
- Data sharing: The BMS provides comprehensive environmental data (e.g., zone-specific temperatures, HVAC status, outdoor weather station inputs) to optimize curtain control strategies.
- Coordinated control: The curtain system shares its status (e.g., shading percentage) or actions with the BMS, allowing HVAC adjustments (e.g., raising setpoints or reducing cooling output when curtains block strong sunlight). This enables cross-system energy efficiency optimization.
③ Implementation
Typically handled by the supplier’s technical team or the hotel’s IT/system integrator, using standard protocols (BACnet, Modbus, MQTT) or custom API connections. Choosing a supplier with mainstream protocol support and proven hotel integration experience is critical.
