Della OS is an all-in-one smart-building operating system designed to unify property systems for integrators, operators, and residents. It allows building owners to onboard or off-board units in minutes, manage access control, smart locks, thermostats, intercoms, CCTV, and other building subsystems through a single platform. The dashboard offers integrations with property-management systems, branded resident apps, event and maintenance workflows, and packaged modules (such as leak detection, Wi-Fi HaLow connectivity, and smart-living features). The value proposition includes potential savings of up to 35% in HVAC energy consumption, reduced vendor fragmentation by centralizing platforms, and improved resident experience with one app controlling smart devices, amenity bookings, and building communications. With a focus on deployment speed, the system claims installation in minutes and supports roles from MSIs (mechanical/electrical integrators) to owner-operators to residents.
