SensorFlow Hotel Energy Management (SmartREM, SmartARC)

SensorFlow Pte Ltd is a Singapore company at Vanguard Campus, Kallang Junction, that provides AI-powered energy management for hotels. It targets air conditioning in guest rooms, which runs in empty rooms and is one of the largest energy costs for hotels in hot climates such as Southeast Asia.

The product line includes SmartREM, a retrofit HVAC-only room energy management system; SmartARC, whole-room control of HVAC, lighting, curtains, occupancy, door sensing and socket-level power over existing wiring; SmartGRD, granular real-time metering of electricity, water and gas; and SmartBEA, free building efficiency analytics on utility data. A wireless gateway links PIR occupancy sensors, door sensors, a smart thermostat for FCU, split, VRV/VRF or chiller systems and a room interface unit to the SensorFlow Cloud, which runs automation and syncs check-in, check-out and room status with major property management systems.

• SmartREM: Retrofits guest-room HVAC control with occupancy-based automation.
• SmartARC: Controls HVAC, lighting, curtains and socket power over existing room wiring.
• PMS integration: Syncs check-in, check-out and room status with major hotel PMS platforms.
• Broad HVAC support: Works with FCU, split, VRV/VRF and chiller systems via a smart thermostat.
• SmartGRD metering: Measures electricity, water and gas in real time at granular level.
• Verified savings: Tracks savings per room with third-party verification available.

A beach resort in Da Nang or Phu Quoc can retrofit guest rooms to switch off air conditioning when rooms are empty. A city business hotel can connect room automation to its PMS to precondition rooms at check-in. A serviced apartment operator can meter electricity and water per unit to support green building reporting.

SensorFlow reports typical guest-room HVAC savings of 20 to 30%, measured room by room against an IPMVP-aligned baseline, and a payback of about two to three years from HVAC savings alone. SmartARC installs in about 90 minutes per room between check-out and check-in, so hotels stay open. The company reports more than 23 million kWh saved and 11,636 tonnes of CO2 avoided.

Hotel brands face rising energy tariffs and sustainability reporting demands, and regulations such as Singapore Green Mark and Vietnam's Decree 30/2026, cited by SensorFlow, are pushing properties toward in-room energy control. Retrofit wireless systems let existing hotels cut cooling costs without rewiring or closing floors.
