i-Cube in the spotlight: Siol.net tests the cube that measures air where you breathe
Slovenian tech portal Siol.net took the i-Cube home for a first-impressions review — a small, portable cube that turns i-Vent ventilation into a system that knows when to work harder and when to save energy.
Measured where people live
Most air-quality sensors sit next to a wall or a ventilation duct, where the air can be quite different from the middle of the room. The i-Cube is light and battery-powered, so it goes where people actually are — the living room by day, the bedroom at night.
It tracks four values that say a lot about indoor air: humidity, temperature, CO₂ and volatile organic compounds from paints, cleaning products, furniture and cooking.
It acts — or asks first
The cube connects wirelessly to the i-Vent system and gets its own tab in the i-Vent app. Every 15 minutes it checks the air and, when something drifts out of range, adjusts the ventilation — automatically, or after the user confirms. Once the air is back to normal, it returns the system to its usual mode.
- One i-Cube can steer up to four i-Vent ventilation units
- Outside temperature is taken into account, so summer heat and winter heat loss are kept in check
- Charged over USB-C for several days of cordless operation
What comes next
The review also brought useful feedback. Clearer low-battery warnings and adjustable sensitivity for the VOC sensor are planned for an upcoming firmware update — exactly the kind of input we build products on.
