How Do I Keep Fragrance Consistent Across Double-Height Living Rooms and Open Staircases?

This is the single most common arithmetic mistake in a villa scenting plan: measuring the double-height living room on its own, forgetting that the open staircase attached to it is not a separate room at all - it is more of the same connected air.

Do the sum properly, in two parts. First, the room itself: length times width times height, divided by 35.3. A 700 sq ft double-height living room at a 20ft ceiling comes to about 396m³ - already more than the same footprint at a normal 10ft ceiling would give you. Second, add the staircase and landing it opens onto, because that volume is genuinely connected to the room below through the open stair: a modest landing and stairwell can easily add another 250-400m³ to the total. Put those together and a real double-height living room with an open staircase often lands at 650-800m³ of genuinely connected air - inside the range of one SOSA Vaayu (₹11,999), placed on the air-conditioning return rather than tucked into a corner, since consistency across a tall, open volume depends on placement more than on the number on the machine's dial. Where the room is larger, taller, or the landing itself is generous, the combined total can pass 1000m³, and the honest step up is a SOSA Angaan (₹25,999) on the HVAC rather than turning one Vaayu higher.

Consistency here is almost entirely a placement question, not an intensity one: never put the machine in the direct path of a supply vent or a fan, because that scatters the fragrance unevenly exactly where you need it steady. None of this connects to a home automation system - it is measured once, placed once, and scheduled once, on site.
