Continuously measure building occupancy to optimize energy use for HVAC and lighting

LightFi’s IoT sensors uses WiFi from mobile phones and smart algorithms to detect live room occupancy, reacting automatically to ameliorate conditions.

Buildings are responsible for 30% of final energy consumption, but upgrading their energy efficiency is complicated and expensive. LightFi is an easy-to-install retrofit solution that requires no rewiring and can connect to existing Building Management Systems. It’s sensors detect occupancy through WiFi radio to create responsive lighting and eating, Ventilation and Air Conditioning (HVAC), optimized to improve indoor air quality while reducing energy consumption. Furthermore, the sensors communicate via cellular networks, removing security risks involved in connecting through private/corporate Wifi network.
