How long before guests should a scent machine run? About an hour ahead is ideal. A short run an hour before lets the scent spread evenly across the floor and settle into a clean signature, rather than being too strong at the door and thin further in. A well-aired room then holds it through the evening.
Can I set it to run for a party automatically? Yes - schedule the run on the app or start a 1h or 4h timer as you prepare. It runs on its own schedule, so you are not fussing with sprays while guests arrive. It is controlled by its own app and timers, not a voice assistant or hub.
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.
The first thing a guest experiences is not what they see - it is what they smell in the first three seconds. Scheduling that moment in advance is the quiet difference between a house and a welcome.

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 do you schedule home fragrance so it is perfect before guests arrive?
Run it about an hour ahead. On a SOSA Vaayu (₹11,999) schedule a run for the hour before guests are due from the Bluetooth app, or simply start a 1h or 4h timer as you begin getting ready. That hour lets a clean, hotel-inspired scent spread evenly across the whole open floor and settle, so the home smells considered from the doorway to the far corner by the time the bell rings - not too strong at the door and thin inside. You are free to focus on the food and the flowers instead of spraying room to room, and a well-aired room holds the scent right through the evening. It is scheduled directly on its own app and timers, running alongside your smart lights and speakers rather than through a hub. One machine covers an open floor up to about 2000-3000 sq ft; a larger gathering space or a multi-storey home may want one per floor or the Angaan (₹25,999). A quick consultation sizes it.
Set the Vaayu to run about an hour before guests, on the app or a 1h timer, so the whole floor is evenly fragranced hands-free.
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 to schedule fragrance so the home is ready before guests arrive
Getting the welcome right is about timing and evenness, not strength. Three things make the pre-guest run land perfectly.
1
Run it an hour ahead
Let the scent settle
A run about an hour before guests gives the scent time to spread across the whole floor and settle into a clean signature. Running it as they walk in makes the door too strong and the far room too faint; an hour ahead makes it even.
Tip: schedule the run about an hour ahead so the scent spreads evenly and settles before the doorbell.
2
Even across the floor
Doorway to far corner
A cold-air machine carries a fine, dry scent across a large open floor, so guests meet the same clean signature at the door, in the living room and at the table - the mark of a considered host.
3
Hands-free while you host
Set it and get ready
Schedule the run on the app or start a 1h timer as you prepare, and it runs itself. No last-minute spraying, no cover-up - just a home that was ready before you were. It runs on its own schedule, not through a hub or voice assistant.
Tip: start it on the app or a timer as you get ready, and it handles the welcome on its own.
The SOSA principle
A guest forgets what you served long before they forget how your home felt to walk into. Scent is the first note of that welcome, and it is the easiest one to prepare in advance.
The most gracious hosting looks effortless because the invisible things - light, temperature, scent - were all quietly scheduled before anyone arrived.
Timing the hosting run and sizing the Vaayu
Timing the hosting run is quick, and sizing follows the volume of the gathering space. Here is how to set it up.
The SOSA scent edit
Timing fragrance for guests
| Scent | Why it suits the mood |
|---|---|
| About an hour before | Schedule the run or start a 1h timer so the whole floor is evenly fragranced and settled by the time guests arrive. |
| A longer evening or party | Use a 4h timer, or a second scheduled burst partway through, to keep a big, busy room feeling fresh as it fills up. |
| A very large gathering space | Size to the volume of air - a very large or double-height entertaining floor may want the Angaan rather than one Vaayu. |
For most homes one Vaayu fragrances the whole entertaining floor up to about 2000-3000 sq ft; a very large or double-height space steps up to the Angaan (₹25,999), and a multi-storey home runs one per floor so upstairs guest areas are welcoming too. It ships with four hotel-inspired oils, so you can choose the signature your guests will remember. 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.
Guests will never mention the scent. They will only say your home felt lovely to walk into - and that is precisely the point.

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 do I schedule home fragrance before guests arrive?
Set the machine to run about an hour before guests are due, so the whole floor is evenly fragranced by the time they arrive. On a SOSA Vaayu (Rs 11,999) you set a run on the Bluetooth app or start the 1h timer as you get ready.
How long before guests should the scent machine run?
About an hour ahead. That lets the scent spread evenly across the floor and settle into a clean signature, rather than being too strong at the door and thin further in. A well-aired room then holds it through the evening.
Will it be too strong by the time guests arrive?
Not if you run it an hour ahead on a moderate setting - it settles into a subtle, even signature. Avoid running it as guests walk in, which concentrates the scent at the door.
Can I keep it fresh through a long party?
Yes - use a 4h timer or a second scheduled burst partway through to top up a big, busy room as it fills. It runs on its own app and timers, so you are not spraying during the evening.
How much space does one machine cover for hosting?
One Vaayu covers an open entertaining floor up to about 2000-3000 sq ft. A very large or double-height space steps up to the Angaan (Rs 25,999), and a multi-storey home runs one per floor.
