Does the Vaayu use Wi-Fi, a hub or voice control? No - it is controlled directly by its own Bluetooth app and built-in timers. It does not connect to Wi-Fi, a smart-home hub, or voice assistants like Alexa, Google Assistant or Siri. It runs on its own schedule alongside your other smart devices.
What does 'automatic' actually mean for the Vaayu? It means you set the schedule once and the machine keeps it - running at your chosen times, idling otherwise, for weeks per tank. The automation is the schedule plus the self-contained cold-air mechanism, not an integration with other systems.
Shop Vaayu ₹11,999
Facts verified August 2026 (SOSA Vaayu product page): The Vaayu is a waterless cold-air diffuser priced at ₹11,999, and each machine ships with four SOSA Hotel Collection fragrance oils of 100ml each (400ml total, about one full tank). It atomises alcohol-free, water-free fragrance oil into a dry nano-mist covering up to 1000m3 (about 2000 to 3000 sq ft), with a 400ml tank that lasts up to about 75 days depending on the intensity setting and daily run hours, and under-38dB operation. Its automation is via Bluetooth app control and built-in 1h/4h/8h/24h timers: you schedule when it runs directly through its own app or timer settings. It is not a hub-integrated, Wi-Fi, or voice-assistant device, and SOSA does not claim it connects to third-party smart-home platforms, voice assistants (such as Alexa, Google Assistant or Siri) or automation hubs; where it appears "alongside" a smart home, that means it runs on its own schedule next to other devices, not integrated into one system. Fragrance is sized to the volume of air, so a very large or double-height floor may need the larger Angaan (₹25,999, ~8,000-10,000 sq ft) or Meenar (₹38,500, ~12,000-18,000 sq ft), and a multi-storey home generally needs one machine per floor - scent does not travel up a staircase on its own. A signature scent enhances a clean, well-ventilated home; it does not remove a musty or closed-up smell, and SOSA makes no medical or air-purification claims. The hotel-inspired scents are SOSA's own original interpretations; SOSA is independent and not affiliated with, or endorsed by, any hotel named for reference. Prices and availability are subject to change - see the live product pages.
If you are weighing up the Vaayu, the honest question is simple: how, exactly, does it automate fragrance? Not vaguely - mechanically. Here is precisely what it does, what controls it, and where the automation stops.

You already automate the invisible parts of the day - lights, curtains, temperature. Fragrance is the one most people leave manual. The SOSA Vaayu automates it: set a schedule once from its Bluetooth app, or use the built-in 1h/4h/8h/24h timers, and your home fills with a clean, hotel-inspired scent on its own - before you arrive, before guests, every day. It runs alongside your other smart devices, each on its own schedule (it is controlled by its own app and timers, not wired into a central hub). One Vaayu covers an open floor of up to about 1000m3 (roughly 2000-3000 sq ft); a multi-storey villa runs one per floor. A quick consultation sizes a large home.

Straight answer
How does the SOSA Vaayu automate home fragrance, exactly?
Through two controls it carries itself: its own Bluetooth app and built-in 1h/4h/8h/24h timers. You set a daily schedule from the app, or pick a timer preset, and the Vaayu (₹11,999) atomises hotel-inspired oil into a dry, waterless cold-air mist at those times - filling an open floor of up to about 2000-3000 sq ft - then idles between runs. You set it once and it repeats on its own, for weeks per tank. That is the whole of the automation, and it is worth being precise about the edge: the Vaayu is controlled directly by its own app and timers, and does not connect to Wi-Fi, a smart-home hub, or voice assistants like Alexa, Google or Siri. It runs on its own schedule alongside your other smart devices, which is all automatic fragrance needs. A quick consultation sizes a large or multi-storey home.
The Vaayu automates fragrance via its own Bluetooth app and built-in 1h/4h/8h/24h timers - schedule it once and it runs itself.
For most homes the answer is one SOSA Vaayu - a waterless cold-air diffuser that carries a clean, hotel-inspired signature scent across an open floor of up to about 2000-3000 sq ft, on a timer, from one discreet machine. A multi-storey villa is one machine per floor, and a very large or double-height floor is sized up to the larger Angaan. It ships with four hotel-inspired oils, so you can find your signature from day one.

How the Vaayu automates fragrance, in detail
The Vaayu's automation has three parts working together. Understanding all three is what makes it clear why you never have to touch it again after setup.
1
The app and timers
Where you set the schedule
You schedule the Vaayu from its own Bluetooth app - daily times it runs and rests - or with built-in 1h/4h/8h/24h presets on the machine. This is the control layer, and it lives entirely on the machine, not on a separate hub or Wi-Fi service.
Tip: the schedule lives on the Vaayu's own app and timers - self-contained, no hub needed.
2
The cold-air mechanism
How it fills the space
At the scheduled times it atomises the oil into a dry, waterless nano-mist - no water, no heat, no residue, under 38dB - and the cold-air throw carries it across an open floor of up to about 2000-3000 sq ft. This is what turns a schedule into a fragranced home.
3
The idle rhythm
Why it lasts weeks
Between scheduled runs the Vaayu rests. That intermittent rhythm keeps the scent fresh rather than heavy, and stretches a 400ml tank to last up to about 75 days. The machine manages this rhythm itself once the schedule is set.
Tip: it runs, then idles - a rhythm that keeps the scent fresh and the tank lasting weeks.
The SOSA principle
Good automation is honest about its own edges. The Vaayu automates fragrance completely on its own terms - a schedule and a self-contained machine - without pretending to be a whole-home ecosystem it is not.
You do not need it wired into everything. You need it to run at the right times and rest the rest - and that is exactly what it does.
Scheduling it and sizing it
The automation is the same at any size; only the machine scales to the air. Here is how it maps out.
The SOSA scent edit
How the Vaayu automates, and how to size it
| Scent | Why it suits the mood |
|---|---|
| The control | Its own Bluetooth app and built-in 1h/4h/8h/24h timers - you set the schedule directly, no hub or Wi-Fi. |
| The reach | One SOSA Vaayu (Rs 11,999) fills an open floor up to ~2000-3000 sq ft; one per floor of a multi-storey home. |
| The rhythm | Runs at your scheduled times, idles between - a 400ml tank lasts up to about 75 days. |
The automation scales cleanly: one Vaayu per open floor up to about 2000-3000 sq ft, a very large or double-height floor stepped up to the Angaan (₹25,999), and a multi-storey home on one machine per floor - each scheduled the same way from its own app and timers. The Vaayu ships with four hotel-inspired oils to run from day one. A quick consultation sizes a large or multi-storey home.
Set it once, forget it
Schedule it once from the app or a timer and the SOSA Vaayu fragrances your home on its own - ₹11,999, Bluetooth app + 1h/4h/8h/24h timers, ships with four hotel-inspired oils.
The Vaayu does not promise to run your whole home. It promises to run one thing perfectly, on its own schedule - and that one thing is the first you notice at the door.

The SOSA automatic-scenting edit
Whichever you choose, every SOSA machine here is made in India and sized to a real volume of air. One signature scent across the whole home, a Vaayu for an open floor up to ~2000-3000 sq ft (one per floor of a villa), and the Angaan or Meenar for a very large or double-height floor. A scent works alongside good ventilation, and the simplest way to size a large or multi-storey home is a quick consultation. Here is the full edit.

One signature scent, scheduled from the app - a Vaayu per open floor, more for a very large or double-height floor
| Machine | Best for | Why it works | From |
|---|---|---|---|
 SOSA Vaayu
|
One open floor up to ~2000-3000 sq ft (1000m3), or one per floor of a villa | Waterless cold-air machine with app & timer - one machine for the whole open floor | ₹11,999 |

|
The signature scent itself (for the Vaayu) | Hotel-inspired, water-based oils - a clean, five-star signature; the Vaayu ships with four | ₹299 |
 SOSA Angaan
|
A very large or double-height floor | HVAC nebulising diffuser for a very large volume of air | ₹25,999 |
 SOSA Sukoon
|
A single closed bedroom, study or pooja room | Ultrasonic cool-mist diffuser for one small room off the main floor | ₹1,899 |
 SOSA Meenar
|
A very large multi-floor residence (12,000-18,000 sq ft) | Commercial HVAC scenting for the biggest homes | ₹38,500 |
How to automate and size it: the Vaayu is scheduled from its Bluetooth app or built-in 1h/4h/8h/24h timers - set it once to run before you arrive, before guests, or on a daily rhythm, and it is hands-free from then on. It runs on its own schedule alongside your smart lights and speakers rather than wired into a central hub or voice assistant. On sizing, fragrance is about the volume of air: one Vaayu fills an open floor of up to about 1000m3 (roughly 2000-3000 sq ft), a multi-storey villa runs one machine per floor (scent does not climb a staircase on its own), and a very large or double-height floor steps up to the Angaan. A closed bedroom or study can take a compact Sukoon. One honest note: a scent enhances a clean, well-aired home and works alongside good ventilation - it is a luxury, not a cover-up. Unsure? A quick consultation sizes it.

A note from Sonal
If you have already automated your lights, your curtains, your AC, you understand the real luxury of a smart home: the best things happen without you thinking about them. Fragrance is the one part almost everyone still does by hand - a spray here, a reed there - and it is the easiest and most rewarding thing to automate. A home that greets you with a clean, hotel-inspired scent the moment you walk in, every single day, without a thought, is a small daily luxury you never tire of.
That is exactly what the Vaayu does. You set a schedule once from its Bluetooth app, or use the built-in 1h/4h/8h/24h timers, and it runs itself - before you get home, before guests arrive, on whatever rhythm suits your day. It sits happily alongside your smart lights and speakers, each on its own schedule, so an arrival can feel genuinely five-star.
One honest note on how it works: the Vaayu is controlled by its own Bluetooth app and built-in timers - you schedule it directly, rather than wiring it into a central smart-home hub or a voice assistant. And size it to the space: one machine per open floor up to about 2000-3000 sq ft, one per floor of a multi-storey villa. A scent enhances a clean, well-aired home; it is a luxury, not a cover-up. Everything is made in India, and a quick consultation sizes a large home.
Frequently asked questions
How does the SOSA Vaayu automate home fragrance?
Through its own Bluetooth app and built-in 1h/4h/8h/24h timers. You set a daily schedule or a timer preset, and it atomises oil into a cold-air mist at those times, filling an open floor up to about 2000-3000 sq ft, idling between runs. Set once, it repeats on its own.
Does the Vaayu use Wi-Fi, a hub or voice control?
No - it is controlled directly by its own Bluetooth app and built-in timers. It does not connect to Wi-Fi, a smart-home hub or voice assistants like Alexa, Google or Siri. It runs on its own schedule alongside your other devices.
What kind of mist does it produce?
A dry, waterless cold-air nano-mist - no water, no heat, no residue - at under 38dB. The cold-air throw carries the scent across a whole open floor rather than pooling in one corner.
How long does it run before a refill?
A 400ml tank lasts up to about 75 days depending on intensity and hours, and the Vaayu ships with 400ml of oil - so it runs its schedule for weeks before a simple top-up.
How large an area does one Vaayu automate?
One Vaayu covers an open floor up to about 2000-3000 sq ft. A multi-storey home runs one machine per floor on the same schedule, and a very large or double-height floor steps up to the Angaan (Rs 25,999).
