Do I have to switch it on each day? No - that is the point. Once you set the daily schedule from the app or a timer, it comes on by itself every day at the times you chose. There is no daily button-pressing, spraying or refilling.
Will it run every day without me topping it up? Yes - 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 daily schedule for weeks before a simple refill.
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 home habits are the ones you never have to keep. A scent machine that comes on by itself, at the same time, every day, without a reminder or a refill, is exactly that kind of habit - one you set once and simply enjoy.

In this guide
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
Can a scent machine really turn itself on every day, unattended?
Yes. Once you set a daily schedule on the SOSA Vaayu (₹11,999) - from its own Bluetooth app or a built-in 1h/4h/8h/24h timer - it turns on by itself at the same times every day and fragrances your home, with no daily effort from you. You set it once and it simply repeats. It runs unattended for weeks, too: it ships with 400ml of oil, and a 400ml tank lasts up to about 75 days depending on intensity and hours. The schedule lives on the machine's own app and timers, not a smart-home hub or voice assistant, so nothing else has to be running for it to keep its daily rhythm. One machine covers an open floor up to about 2000-3000 sq ft. A quick consultation sizes a large or multi-storey home.
Yes - set a daily schedule once on the Vaayu's app or a built-in timer, and it turns on by itself at the same times every day.
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 daily automatic running works
Three things make a daily automatic run trustworthy: the schedule holds, the oil lasts, and it does not depend on anything else. The Vaayu has all three.
1
The daily schedule holds
Same times, every day
You set the daily times once from the Bluetooth app, or a 1h/4h/8h/24h timer preset, and the machine keeps to them day after day. It does not need re-setting each morning - a daily rhythm is exactly what it is built for.
Tip: set the daily times once and the machine keeps them every day, unprompted.
2
The oil lasts weeks
Up to ~75 days a tank
An automatic daily run is only useful if it does not run dry quietly. The Vaayu ships with 400ml, and a 400ml tank lasts up to about 75 days depending on intensity and hours - so it runs its daily schedule for weeks before a simple top-up.
3
It runs unattended
Its own controls, no hub
Because the schedule lives on the Vaayu's own app and timers, nothing else has to be on for it to run. No hub, no Wi-Fi routine, no voice assistant. It keeps its daily rhythm alongside your other devices, entirely on its own.
Tip: nothing else has to be running - the daily schedule lives on the machine itself.
The SOSA principle
A daily luxury only feels effortless if it truly asks nothing of you. The test of an automatic scent machine is whether you forget it is there - and still notice the home the moment you walk in.
Set the daily run to your own rhythm and, within a week, you stop thinking about home fragrance at all. It has simply become part of the house.
Setting the daily run and sizing the machine
The daily run is set in a moment. The only decision that carries weight is sizing the machine to your space.
The SOSA scent edit
Setting the daily run, and sizing it
| Scent | Why it suits the mood |
|---|---|
| Set the daily schedule | From the Vaayu's Bluetooth app, or a 1h/4h/8h/24h timer - it then turns on by itself at those times every day. |
| It runs for weeks | 400ml ships in the box; a 400ml tank lasts up to about 75 days depending on intensity and hours. |
| Size to the floor | One Vaayu (Rs 11,999) per open floor up to ~2000-3000 sq ft; one per floor of a multi-storey home. |
Set the daily schedule once and one Vaayu handles an open floor up to about 2000-3000 sq ft on its own. A very large or double-height floor steps up to the Angaan (₹25,999), and a multi-storey home runs one machine per floor on the same daily schedule. It 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 best things in a home are the ones you set once and stop noticing you set. A scent that arrives every day, unasked, is one of them.

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.

| Machine | Best for | Why it works | From |
|---|---|---|---|

 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.
