Should scent start before guests or when they arrive? Before. Fragrance needs a little time to settle and spread evenly, so schedule it to begin roughly an hour before guests rather than at the moment they walk in - that way the scent reads as background warmth, not a fresh spray. On the SOSA Vaayu you set this once from the app or a timer preset.
Can one machine fragrance a whole party floor? One SOSA Vaayu covers an open floor of up to about 1000m3 (roughly 2000 to 3000 sq ft), which is most living-and-dining party spaces. A multi-storey home runs one machine per floor, and a very large or double-height great room steps up to the Angaan.
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 best hosts do not rush around at 6:55. They let the house get itself ready - lights warm, room cool, and the whole place already smelling clean and welcoming - so that by the time the bell rings at seven, all they do is open the door.

How do you automate a home before guests arrive? Put each part of the room on its own schedule so they are all ready at the same time: lights on a timer, cooling started early, and fragrance running ahead of the door. A cold-air scent machine like the SOSA Vaayu (Rs 11,999) uses its own Bluetooth app and built-in 1h/4h/8h/24h timers, so you can schedule it to start about 45 to 60 minutes before guests and the home is evenly, gently fragranced by the time anyone arrives. Each device runs on its own schedule alongside the others, not through a single hub. Made in India.Should scent start before guests or when they arrive? Before.

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 I get my home guest-ready automatically before people arrive?
Let the house prepare itself. Put each part of the room on its own schedule so everything peaks together at seven: lights on a timer, cooling started ahead, and - the part most people still do by hand - fragrance running before the door. A SOSA Vaayu cold-air diffuser (₹11,999) makes the scent automatic: you schedule it once from its Bluetooth app, or use the built-in 1h/4h/8h/24h timers, to start about 45 to 60 minutes before guests. By the time anyone rings, the whole floor is evenly and gently fragranced - background warmth, not a fresh spray. It is controlled by its own app and timers rather than wired into a smart-home hub or voice assistant, so it simply runs on its own schedule alongside your smart lights and speaker. One machine covers an open floor up to about 2000 to 3000 sq ft; a multi-storey home runs one per floor. Not sure of your size? A quick consultation sorts it.
Put lights, cooling and scent each on their own schedule so all three are ready together - and start the Vaayu about an hour before guests so the scent settles evenly.
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 automate a home before guests arrive
Automating a home for guests is really about timing three simple things so they land together. Here is how each one works, and where fragrance fits.
1
Start the scent early
About 45 to 60 minutes before guests
Fragrance needs a little time to spread and settle. Schedule the Vaayu to begin roughly an hour before people arrive, and by seven the room reads as gently, evenly welcoming rather than freshly sprayed.
Tip: schedule the scent to start about 45 to 60 minutes ahead, so it settles into background warmth.
2
Keep it at background level
Welcoming, never overpowering
A party is warm bodies, food and conversation, so you want scent as a quiet layer, not the loudest thing in the room. A moderate setting that fills the floor softly is far more elegant than an intense one.
3
Everything on its own schedule
Aligned, not integrated
Set your lights, your speaker and the Vaayu each to come on around the same time. They run in parallel on their own schedules rather than through one hub, which is all a guest-ready room actually needs.
Tip: set each device to the same start time so they align, each running on its own schedule.
The SOSA principle
A guest never notices the effort you put in before they arrive - they only notice how the room feels the moment they step in. That feeling is worth automating.
Lights and cooling set the comfort; scent sets the welcome. When all three are already in place at the door, hosting stops feeling like a scramble.
Scheduling and sizing the Vaayu for hosting
Setting it up takes a minute, and sizing simply follows the volume of your party floor. Here is how it maps out.
The SOSA scent edit
How to schedule and size it for hosting
| Scent | Why it suits the mood |
|---|---|
| Schedule (app or timer) | Set the Vaayu from its Bluetooth app, or a 1h/4h/8h/24h timer, to start about 45 to 60 minutes before guests arrive. |
| One open party floor up to ~2000-3000 sq ft | One SOSA Vaayu (Rs 11,999) covers it; a multi-storey home runs one per floor on the same start time. |
| A very large or double-height great room | Step up to the Angaan (Rs 25,999) for a bigger volume of air; a consultation sizes it. |
If your entertaining space is very large or spread over floors, run one Vaayu per floor set to the same start time, or step a big open volume up to the Angaan (₹25,999). The Vaayu ships with four hotel-inspired oils, so you can settle on your signature and schedule it 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.
You automated the lights so no one walks into a dark house. Automate the scent so no one walks into a home that does not already feel like a welcome.

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.

|---|---|---|---|

|

|
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 early should I start the scent before guests arrive?
About 45 to 60 minutes before. Fragrance needs a little time to spread and settle, so schedule the SOSA Vaayu (Rs 11,999) to begin roughly an hour ahead and the home reads as gently welcoming, not freshly sprayed, by the time anyone rings the bell.
Can I really automate my whole home before guests?
You can automate the parts that matter for a welcome. Put lights and cooling on their own timers and schedule the Vaayu to run ahead of the door, and the room is ready together - each device on its own schedule, running alongside the others.
Does the Vaayu connect to Alexa, Google Home or a smart-home hub?
No. The Vaayu is scheduled through its own Bluetooth app and built-in 1h/4h/8h/24h timers, not through voice assistants or a central hub. It runs on its own schedule next to your other smart devices, which is all you need for automatic fragrance.
What intensity should I use for a party?
A moderate, background level. You want scent as a quiet welcoming layer rather than the loudest thing in a room full of food and conversation, so set the Vaayu to fill the floor softly rather than at full intensity.
How much space does one machine cover?
One Vaayu covers an open floor of up to about 2000 to 3000 sq ft (1000m3), which suits most living-and-dining party spaces. A multi-storey home runs one machine per floor, and a very large or double-height room steps up to the Angaan (Rs 25,999).
