Is home scenting an automation-integrator's decision, since it is part of a smart home? Not primarily. Neither SOSA machine connects to a control system - no Control4, Crestron, KNX or Matter - so it is not a decision that lives inside the integrator's usual scope of work. It is an airflow and placement decision, which sits with whoever plans the HVAC and the interior finishes.
Should the architect be the one to decide where the scent machine goes? The architect sets the layout and ceiling heights that the decision depends on, but the actual placement - clear of a supply vent, near the return air - is a more detailed call best made by the HVAC consultant and interior designer once those drawings exist.

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, a DC 12V/1A power draw of about 5W, dimensions of 165 x 80.5 x 215mm at 0.9kg, freestanding or wall/HVAC mounting, auto-stop, key-lock, 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 integrates with a smart-home protocol, a control system, sensors or voice assistants - both are scheduled standalone machines controlled from an on-site Bluetooth app. 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.
Every trade on a luxury project has a reasonable claim to this question, and the honest answer flatters none of them: it belongs to whoever owns the air handling, working with the interior designer, because scenting rides the air rather than the network.
Quick answers — read this first
Who should plan home scenting - the architect, interior designer or automation consultant? Whoever owns the air handling, working with the interior designer - usually the HVAC consultant, since a SOSA Vaayu (₹11,999) or Angaan (₹25,999) is placed by where the air moves, not by which control system runs the home. The automation integrator is involved because they are already coordinating services on site, not because scenting is a control-system decision.Is home scenting an automation-integrator's decision, since it is part of a smart home? Not primarily. Neither SOSA machine connects to a control system - no Control4, Crestron, KNX or Matter - so it is not a decision that lives inside the integrator's usual scope of work. It is an airflow and placement decision, which sits with whoever plans the HVAC and the interior finishes.
Should the architect be the one to decide where the scent machine goes? The architect sets the layout and ceiling heights that the decision depends on, but the actual placement - clear of a supply vent, near the return air - is a more detailed call best made by the HVAC consultant and interior designer once those drawings exist.
The short answer
Short answer: the HVAC consultant and interior designer, together - because placing a SOSA Vaayu (₹11,999) or Angaan (₹25,999) is an airflow decision, not a control-system one; the automation integrator is involved for coordination since they are already on site, not because it is their decision to own.
The pick: the SOSA Vaayu (₹11,999) placed by the HVAC consultant and interior designer, or the SOSA Angaan (₹25,999) for a home on central HVAC.

Straight answer
Between the architect, interior designer and automation consultant, who should actually plan home scenting?
The honest answer is the HVAC consultant and the interior designer, together - and the reason is worth being precise about, because it is not a status judgment on any trade. A SOSA Vaayu (₹11,999) or SOSA Angaan (₹25,999) is placed correctly by understanding where the air actually moves: clear of a supply vent's throw, near the return path, accounting for an open stairwell's chimney effect. That is HVAC knowledge, not control-system knowledge or purely aesthetic knowledge, which is why the HVAC consultant is the closest natural fit - working alongside the interior designer, who owns the mount position within the room's finishes and joinery. The architect's role comes earlier: the layout and ceiling heights that make the airflow calculation possible in the first place are theirs to set, even though the detailed placement decision usually lands later, once HVAC and interior drawings exist. The automation integrator is genuinely involved, but for a different reason than most people assume - not because scenting is a control-system decision, but because the integrator is already coordinating electrical points and low-voltage runs across the project, and the scent machine's power point is one more item on that same coordination list. Neither machine speaks to a control system. There is no Control4, Crestron, Lutron, KNX or Matter driver, no wifi, no cloud account, and no voice-assistant skill. Vaayu is operated from its own on-site Bluetooth app with 1h/4h/8h/24h timers; Angaan runs its own programmable schedule. Both are scheduled and standalone, which is exactly what makes them simple to specify and simple for a homeowner to run once the project is handed over. It would be flattering no trade, and inaccurate, to hand this decision entirely to any single one of the four. The honest structure is: HVAC consultant and interior designer decide placement, architect sets the conditions that decision depends on, and the automation integrator coordinates the practical connection alongside everything else they are already running. A conversation that includes your HVAC consultant and interior designer together is the fastest way to get this right the first time. A portion of every order supports girl-child education through Nanhi Kali.
The HVAC consultant and interior designer, together - because placement follows airflow, not the control system. The architect sets the conditions; the automation integrator coordinates the point, but does not own the decision.
Placing the SOSA Vaayu is an airflow decision, so the HVAC consultant and interior designer are the natural owners - not the automation integrator, since the machine has no control-system driver to configure. ₹11,999.

Why this is an airflow decision, not a control-system one
Four trades, four legitimate claims, and one honest way to divide the actual decision between them.
1
The architect sets the conditions
Layout and ceiling heights, decided earlier in the project
The architect's drawings establish the ceiling heights, room volumes and stairwell arrangement that make an airflow-based placement decision possible in the first place. That is a genuine contribution, even though the detailed placement call - exactly where the machine sits - typically comes later, once HVAC and interior drawings exist to work from.
Tip: sets the stage; does not usually make the final placement call.
The Vaayu's placement depends on room volumes the architect has already established, which is why the timing question in this cluster keeps returning to the architect's drawings.
See SOSA Vaayu →
2
HVAC consultant and interior designer own it
Airflow expertise plus finish and joinery knowledge
Placement is decided by where the air moves - clear of a supply vent, near the return, accounting for a stairwell's chimney effect - which is HVAC expertise, paired with the interior designer's knowledge of where a mount can sit within the room's finishes and joinery. Together, these two have the actual information the decision needs.
For a home on central HVAC, the Angaan connects directly into the HVAC consultant's system, making their ownership of the decision even more direct.
See SOSA Angaan →
3
The automation integrator coordinates, but does not own it
Involved because they are already on site, not because it is a control decision
The integrator is usually the one running electrical and low-voltage coordination across a project, so the scent machine's power point naturally becomes one more item on their list. That is a real and useful role. It is not the same as owning the decision, because neither SOSA machine has a driver, scene trigger or protocol for the integrator to actually configure into the home's control system.
Tip: coordinates the point. Does not program the machine into anything.
The Vaayu's complete independence from any control platform is exactly why this role stays limited to coordination rather than ownership.
See SOSA Vaayu →
The SOSA principle
This decision has no natural owner among the trades that usually claim smart-home questions, precisely because it rides the air rather than the network. That is an honest answer, not a diplomatic one.
The question is never which trade is most senior on the project. It is which trade actually has the information the decision depends on.
One Vaayu per zone, one Angaan for a home already on central HVAC
The machine choice does not change who owns the decision - a Vaayu placed by airflow logic for most homes, an Angaan tied directly into the HVAC consultant's system for a home already on central HVAC.

Once ownership is clear, the practical steps follow the rest of this block directly: how interior layout and airflow affect placement covers the physics the HVAC consultant is applying, and when an architect should plan scenting covers the earlier timing question the architect owns. The pillar guide on automating home fragrance is worth sharing with an automation integrator specifically, since it states plainly what the machines do and do not connect to.

A note from Sonal
I get asked this question most often by automation integrators themselves, and they are usually relieved by the honest answer rather than disappointed by it. Scenting is one of the few decisions on a smart-home project that genuinely is not theirs to own, and saying so plainly saves everyone a misplaced expectation later.
My structure for any project team asking this is straightforward: the Vaayu or Angaan is placed by whoever understands where the air moves - usually the HVAC consultant - working with the interior designer on where the mount sits within the finishes. Neither machine speaks to a control system. There is no Control4, Crestron, Lutron, KNX or Matter driver, no wifi, no cloud account, and no voice-assistant skill. Vaayu is operated from its own on-site Bluetooth app with 1h/4h/8h/24h timers; Angaan runs its own programmable schedule. Both are scheduled and standalone, which is exactly what makes them simple to specify and simple for a homeowner to run once the project is handed over. The automation integrator's real job is coordinating the power point alongside everything else they are running, which is valuable, but it is not the same as owning the placement decision.
No trade in this list is more or less important for not owning it - the decision simply belongs where the relevant information lives, which happens to be airflow rather than automation. Everything is made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
Who should plan home scenting - the architect, interior designer or automation consultant?
The HVAC consultant and interior designer, together, since placing a SOSA Vaayu (Rs 11,999) or SOSA Angaan (Rs 25,999) is an airflow decision, not a control-system one. The architect sets the layout and ceiling heights the decision depends on, and the automation integrator coordinates the power point because they are already on site, not because it is their decision to own.
Is home scenting an automation integrator's responsibility, since it is part of a smart home?
Not primarily. Neither SOSA machine has a Control4, Crestron, KNX or Matter driver, so it does not sit inside the integrator's usual control-system scope. Their genuine role is coordinating the power point alongside other services already being run.
Why is the HVAC consultant the closest fit for this decision?
Because correct placement depends on understanding where the air actually moves - clear of a supply vent, near the return path, accounting for a stairwell's chimney effect - which is HVAC expertise rather than a control-system or purely aesthetic judgment.
What role does the interior designer play if the HVAC consultant owns placement?
The interior designer decides where the mount can sit within the room's finishes and joinery once the HVAC consultant has identified where the air moves - the two work together, since airflow and finish both constrain the final spot.
Does the architect need to be involved in this decision at all?
Yes, earlier in the project - the architect's layout and ceiling heights are what make the later airflow calculation possible. The detailed placement decision itself usually comes after those drawings exist, once HVAC and interior design can work from them.
