How Should I Plan Airflow, Electrical Points, Scent Zones, Machine Placement, Fragrance Schedules, Bedrooms, Double-Height Living Areas and Whole-Home Scent Automation Alongside Lighting, HVAC, Curtains and Audio?

Start by defining automated honestly, because every other decision depends on getting this right first. Vaayu and Angaan do not join your control system. There is no wifi, no cloud account, no Alexa or Google Home skill, and no Control4, Crestron, Lutron, KNX, Matter, Zigbee or Z-Wave integration - naming those systems here is only to be precise about what is not present, never to claim compatibility with any of them. What they do have is a repeating clock-based schedule, set once on the machine's own Bluetooth app or its onboard programming, that runs every day with nobody touching a switch. Say that plainly to your integrator and your client before specifying anything - a home built on the promise of "everything in one app" needs to know fragrance is the one system that sits outside it. What automation genuinely delivers here is different, and still valuable: both machines hold a repeating daily schedule - 1h/4h/8h/24h timers on the Vaayu, programmable schedules on the Angaan - set once and run every day with nobody touching a switch. There is a reason a scene-triggered burst would be the wrong model even if SOSA's machines could take a trigger. Lighting changes in milliseconds and blinds move in seconds, but a room's air takes roughly twenty to forty minutes to reach an even, settled fragrance level, and just as long to clear - a "welcome home" button that fires fragrance the moment a door opens is physically too late, and if the level is set high enough to register in that first moment, it is already too strong by the tenth minute, because a fresh nose notices a change and then stops registering it within a few minutes while the room keeps accumulating. The arrival effect people actually want is produced by a fresh nose walking into a room that has already been held at a low, settled level for the last hour - which is exactly what a schedule does and a trigger cannot. That is worth internalising before the rest of the plan, because it means every zone below should be designed around a schedule, never around a hoped-for trigger. Second, the design-stage checklist, and this is the part that has to happen while the ceiling void and wall cavities are still open, not after handover. Decide the mount for each machine - the Angaan connects to the HVAC or wall-mounts, the Vaayu can be freestanding, wall or HVAC mounted - and choose the exact position for each. Run a discreet 5W power point to that position while wiring is exposed; 5W is a trivial electrical load, so this is purely a placement and joinery-timing question, never a capacity one. And choose a position clear of any supply vent's direct path, in coordination with whoever is drawing the HVAC layout, since a machine sitting in an air vent's airflow disperses unevenly. All three of these are cheap now and visibly compromised later - a machine on a shelf where a recessed mount belonged, a trailing cable across finished skirting, a position chosen for convenience instead of airflow. Third, measure volume, not floor area, floor by floor. The arithmetic is simple and worth doing honestly for every distinct volume in the house: square footage times ceiling height, divided by 35.3, gives cubic metres. A normal-height room at 10 ft is straightforward; a double-height living room at 18 or 20 ft holds far more air than its floor plan suggests, and this is exactly where floor-area shortcuts mislead a whole-home plan. Work out each floor's connected volume separately, since different air-conditioning zones behave as different fragrance zones too. Fourth, treat any open staircase as a chimney, not a corridor. Warm air and fragrance rise through an open stairwell the way smoke rises through a flue, which means a machine placed only at ground level under-serves the ground floor and over-serves the landing and upper corridor above it. Plan the stairwell's volume into whichever floor's machine is closest to it, and expect the upper landing to need less direct scenting than the ground floor that is actually feeding it. Once volume and zoning are settled, the machine choice follows directly: one SOSA Angaan (₹25,999, up to 3,000m³) for the main double-height volume or for a floor already running one central ducted AC system, and one SOSA Vaayu (₹11,999, up to 1000m³) per normal-height zone elsewhere in the house. Fifth, the bedroom exception, which is the one place in this whole plan where the honest answer runs against the instinct to make everything consistent. A bedroom is small, fully enclosed, and occupied for roughly eight hours by someone who cannot leave, often shared with a partner who did not choose the scent - so bedrooms should run lighter than the living areas, or clear, and the main house machine should never be positioned to feed a bedroom directly through its supply air. A flameless reed diffuser on a bedside chest is very often the genuinely better answer for a bedroom specifically, and it is worth saying so rather than defaulting every room in the house to the same automated system just because the rest of the house has one. Sixth, schedule the whole system rather than trying to trigger any part of it - start each zone's run 30 to 60 minutes before the household's typical activity there, at a low, considered intensity, using the same fragrance throughout the home so the transition between floors and rooms reads as one house rather than several decisions bumping into each other. And finally, build in the discipline that keeps an automated home from over-scenting itself, because this is genuinely the easiest way to get this whole plan wrong: run hours, not all day - a few hours morning and evening beats a 24-hour continuous run, uses less oil, and stays where a visitor would find it pleasant rather than where residents have simply stopped noticing it. Judge the level from outside: walk out for ten to fifteen minutes and come back in, or ask someone who does not live there, since residents adapt to a constant smell within days and become the worst possible judges of its strength - this is precisely why nobody catches an over-scented automated home from the inside. If a guest ever comments on the fragrance, unprompted, it is too strong; turn it down. And when the whole system is first commissioned, start lower than feels right and hold that setting for a week before changing anything, because the temptation to turn it up on day one, before anyone has adapted, is exactly how automated homes drift toward too strong within the first month. Ask for a home scenting plan and send your complete drawing set, with ceiling heights and the AC layout marked floor by floor - we will build this whole plan with you rather than hand you a single number for the entire house.
