Product description

LightFi’s Occupancy-Sensing IoT Hardware & Demand Control Ventilation (DCV) Platform is a cutting-edge solution designed to revolutionize building energy management. The core of this innovative system is the Base Pro device, a modular hardware platform that integrates seamlessly with various sensors to provide real-time occupancy data for demand-based HVAC control.

The Base Pro device measures floor-level WiFi occupancy and serves as a gateway for other sensors like Sahara for CO₂ and PM₂.₅ levels, Alpine for humidity/temperature monitoring, and X1 for desk-level presence detection. These sensors work together to collect live data, which is then transmitted to the LightFi portal or directly to a building’s BACnet-based Building Management System (BMS).

By leveraging this data, the platform enables automated ventilation control, adjusting airflow to increase fresh air in occupied spaces and reduce it in empty rooms. This dynamic approach not only leads to significant energy savings but also improves indoor air quality and reduces occupant complaints.

In addition to the hardware and software components, LightFi offers customized HVAC consulting services and ROI projections based on client metering data. The system is GDPR-secure and certified to Cyber Essentials standards, ensuring robust hardware security for enterprise-grade applications.

Targeting a wide range of commercial spaces such as offices, airports, retail establishments, and universities, this solution delivers tangible sustainability benefits and operational comfort with minimal installation complexity.

About the Company

LightFi is a UK-based cleantech startup founded in 2016 in London. The company offers wireless IoT sensors and building automation solutions that dynamically monitor space occupancy and indoor air quality. By integrating patented long-range WiFi-based occupancy sensing with environmental data (CO₂, temperature, humidity, particulate matter), LightFi enables smart HVAC automation through existing building management systems. This reduces energy usage by 10–25% and typically provides a return on investment within 9–24 months. LightFi’s lightweight sensors—including Base Pro, Alpine, Sahara, X1, and Hoth—are designed for plug-and-play deployment, requiring no rewiring. Its cloud-connected platform and BACnet/IP compatibility enable real-time data visualization, demand-control ventilation strategies, and predictive analytics. Trusted by clients such as Transport for London, British Gas, Heathrow Airport, and universities, LightFi supports healthier indoor environments and improved operational efficiency for buildings worldwide.
