Can fragrance be included in a Guests Arriving trigger like lighting and music? No. SOSA Vaayu and Angaan have no wifi, cloud or smart-home integration, so neither fires on a scene trigger. The honest and better approach is a scheduled baseline that is already running before guests arrive, which produces the effect a trigger never could.
How far ahead should fragrance start before guests arrive? One to two hours, at a low intensity, using the Vaayu's app timer or the Angaan's programmable schedule. This gives the room time to reach an even level, so guests meet a space that already smells settled rather than one reacting to their arrival.

Facts verified 24 August 2026 against the live SOSA product pages: the SOSA Vaayu (₹11,999) is a waterless cold-air nebuliser rated to 1000m³ (about 2,000-3,000 sq ft), with a 400ml refillable tank lasting up to about 75 days depending on intensity and run hours, a Bluetooth app and onboard buttons with 1h/4h/8h/24h timers and adjustable intensity, operation under 38dB, freestanding or wall/HVAC mounting, auto-stop, key-lock for public spaces, and CE, RoHS and SGS certification. The SOSA Angaan (₹25,999) is an HVAC nebulising diffuser rated to 3,000m³ (about 8,000-10,000 sq ft) with an 800ml reservoir, metal body, programmable schedules and operation under 42dB, connecting to the building's HVAC or running standalone wall-mounted. Neither machine has wifi, a cloud connection, a voice-assistant integration, a smart-home protocol integration, occupancy or door sensors, geofencing, or automatic intensity ramping, and neither responds to a scene trigger of any kind. Scent enhances the ambience and perceived quality of a space; it works alongside proper ventilation and cleaning and is not a substitute for either, and SOSA makes no claim that fragrance alone influences a purchase decision. The hotel-inspired scents are SOSA's own original interpretations; SOSA is an independent brand and is not affiliated with, or endorsed by, any hotel named for reference. Coverage, fragrance usage and running cost depend on the space, settings and hours of use, and are confirmed on a consultation. Prices and availability are subject to change - see the live product pages.
A genuinely good Guests Arriving scene has two different mechanisms hiding inside it, and knowing which is which is the whole trick: lighting and music can fire the instant the gate opens, and fragrance cannot - it has to already be finished by then.

How do I create a multisensory Guests Arriving scene at home? Build it in two halves. Let your lighting and music scenes fire the moment guests arrive, since both can genuinely respond that fast. For fragrance, start the SOSA Vaayu (₹11,999) schedule one to two hours ahead instead, at a low intensity, because a room needs twenty to forty minutes to settle and cannot be triggered on arrival the way light and sound can.Can fragrance be included in a Guests Arriving trigger like lighting and music?

The short answer
Short answer: in two halves - let lighting and music fire on arrival as usual, and start the SOSA Vaayu (₹11,999) or Angaan (₹25,999) fragrance schedule one to two hours ahead instead, since fragrance has no scene trigger and needs that time to settle.
The pick: the SOSA Vaayu (₹11,999) started an hour or two ahead for most homes, stepping up to the SOSA Angaan (₹25,999) for a whole villa reception run on HVAC.

Straight answer
How do I build a Guests Arriving scene that includes fragrance?
Split it honestly into two halves. Your lighting and music can genuinely be part of a scene that fires the moment a guest arrives - both change fast enough for that to work. SOSA's machines do not connect to scenes. There is no wifi and no cloud account, no voice assistant such as Alexa, Google Home or Siri, and no integration with Control4, Crestron, Lutron, KNX, Matter, Zigbee or Z-Wave. There are no scene triggers and no occupancy, door or geofencing sensors. A Vaayu will not appear as a device in anyone's control system and will not fire on a button press. That is not really a gap, because scene-triggered fragrance is the wrong model to begin with. Fragrance is the one layer of a smart home that cannot respond on a trigger the way lighting or blinds can. Lights change in milliseconds; a room's air takes twenty to forty minutes to reach an even, settled level, and just as long to clear. A scene that fires fragrance the instant a door opens is physically too late to be the thing anyone actually smells at that moment. And if the level is set high enough to register instantly, it is already too strong by minute ten, because a fresh nose adapts within minutes while the room keeps accumulating behind it. The model that genuinely works is a low continuous baseline on a schedule: the effect people want is not produced by a machine firing on arrival, it is produced by a fresh nose walking into a room that has already been held quietly at a low level for an hour. That is also exactly why a well-run hotel lobby holds a constant low level rather than triggering anything at the door. So the fragrance half of a Guests Arriving evening is not a trigger at all - it is a schedule you start one to two hours before your guests are due, at a low intensity, on the SOSA Vaayu (₹11,999) or, for a whole villa reception run, the SOSA Angaan (₹25,999) on the HVAC. By the time the doorbell rings, the room has already reached a settled level, and your guests - arriving with fresh noses from outside - register it in a way you, having been in the house all evening, no longer can. That asymmetry is actually the whole point: the host's adapted nose and the guest's fresh one experience the same room differently, and the schedule is built for the guest. A portion of every order supports girl-child education through Nanhi Kali.
Let lighting and music fire on arrival - they can. Start the fragrance schedule one to two hours ahead instead, because it cannot be triggered and needs the time to settle.
The SOSA Vaayu holds a repeating 1h/4h/8h/24h schedule you start one to two hours before guests arrive, so the room is already settled by the time the doorbell rings. Waterless, under 38dB. ₹11,999.

Building the scene - what can fire on arrival, and what has to be ready already
A Guests Arriving scene is really two scenes stitched together at different speeds. Here is how to build each half properly.
1
Let lighting and music do what they do
Both can genuinely fire the moment a guest arrives
There is no honesty problem here - lighting scenes and music can absolutely be set to trigger on a doorbell, a gate sensor or a tapped button, and they will respond instantly. Build that half exactly as your integrator normally would. The only layer that needs a different approach is fragrance.
Tip: do not hold back the parts that genuinely work instantly.
The Vaayu is simply not part of that instant-trigger half of the scene, and should not be asked to be.
See SOSA Vaayu →
2
Start fragrance one to two hours early
It has to be finished, not fired, by the time guests appear
Set the Vaayu's app timer or the Angaan's programmable schedule to begin one to two hours before your guests are expected, at a low intensity. This is the single most important practical fact in this whole guide - skip it and the fragrance is either absent or, worse, switched on in a panic right before the door and noticeably fresh rather than settled.
For a whole villa reception, the Angaan's schedule can be set once for every event rather than adjusted each time.
See SOSA Angaan →
3
Trust the guest's fresh nose
You will stop noticing it before your guests even arrive
As the host you have likely been in the house for hours and will register the fragrance far less than someone walking in from outside. That is not a failure of the schedule - it is exactly how it is supposed to work. Do not raise the intensity because you personally cannot smell it anymore; ask a family member who just came home, or trust the low setting.
Tip: if you can still smell it strongly as the host, it is probably too strong for your guests.
A second, lighter Vaayu zone for a terrace or secondary reception area keeps outdoor spaces from over-accumulating.

The SOSA principle
A Guests Arriving scene is not one moment. It is a room that was quietly prepared for the last hour, met by lighting and music that fire in the last second.
Two different speeds, two different mechanisms, one evening that feels seamless to the guest who never sees either.
Vaayu for most homes, Angaan for a whole villa on HVAC
The machine choice is about how large the reception area is - both hold the pre-arrival schedule equally well.

A quick word on choosing: build the lighting and music half of the scene to trigger on arrival as normal, and treat fragrance as a separate schedule started one to two hours early. One honest note - the two halves never speak to each other technically, and that is exactly why the evening works. A free scenting plan will help time it to your typical guest list.

A note from Sonal
The clients who get the most out of a Guests Arriving scene are the ones who stop trying to make fragrance behave like their lighting. Once they accept that it runs on a completely different clock, planning it becomes simple rather than frustrating.
My advice is always the same: build the lighting and music trigger exactly as your integrator normally would, since both genuinely can respond the instant a guest arrives. Then treat fragrance separately - start the Vaayu (₹11,999) or Angaan (₹25,999) one to two hours before the first guest is expected, at a level you can barely notice yourself by the time they walk in. That is not the schedule failing to keep up. That is the schedule working exactly as it should.
The nicest thing about this approach is that you, the host, are the worst judge of whether it is working - you have been breathing that air for hours and stopped noticing it, which is precisely the point. Trust the low setting and the early start. Everything is made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
How do I create a multisensory Guests Arriving scene that includes fragrance?
Build it in two parts. Let your lighting and music scenes trigger on arrival as usual, since both change fast enough to respond instantly. For fragrance, start the SOSA Vaayu or Angaan schedule one to two hours before guests are expected instead, at a low intensity, so the room is already settled by the time they walk in.
Can fragrance be triggered at the same moment as the lighting scene when guests arrive?
No. SOSA Vaayu and Angaan have no wifi, cloud account or smart-home integration, so neither can be included in an instant scene trigger. Fragrance takes twenty to forty minutes to reach an even level, which is why it has to be started well ahead of time rather than fired on arrival.
How far ahead of a guest arrival should the fragrance schedule start?
About one to two hours, at a low intensity. This gives the room time to settle so guests, arriving with a fresh nose from outside, notice a room that already smells considered rather than one that smells freshly switched on.
Why can't I smell the fragrance as strongly as I expect when guests arrive?
Because you have likely been in the house for hours and have adapted to the smell, while your guests have not. This is expected and correct - do not raise the intensity based on your own nose; a lower setting than feels satisfying to you is usually right for a guest walking in fresh.
Should an outdoor terrace used for guests follow the same fragrance schedule as the indoor reception rooms?
Use a separate, lighter zone for outdoor or semi-outdoor areas rather than the same schedule as the indoor rooms. Outdoor air moves and dilutes fragrance differently, so a second Vaayu at a lower intensity usually reads better than extending the indoor setting outward.
