Can head office monitor scent machine settings remotely across multiple locations? No - the SOSA Vaayu app is Bluetooth and short-range, on-site control only, with no cloud connection or remote dashboard. This is exactly why the SOP has to name a written setting per site rather than describe a sensation, because there is no way to audit a branch's actual setting from head office.
What should a multi-location scenting SOP include? A named fragrance, a named setting per site type, a map of scented and neutral zones by room, a named person per site who holds the app, a refill interval and who checks it, and a complaint route where one complaint ends with the fragrance switched off in that zone - plus a monthly check by someone who does not work at that location.

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, described by the manufacturer as approximately 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 with 1h/4h/8h/24h timers and adjustable intensity for on-site control only, operation under 38dB, freestanding or wall and HVAC mounting, auto-stop and key-lock, and CE, RoHS and SGS certification. The SOSA Angaan (₹25,999) is an HVAC nebulising diffuser rated to 3,000m³, roughly 8,000-10,000 sq ft, with an 800ml reservoir, metal body, programmable schedules and operation under 42dB, and also runs standalone wall-mounted or lay-flat. 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.
Growing from one flagship to fifteen locations is exactly the moment to formalise scenting - but the honest SOP is narrower and more specific than most brands expect, because the app that runs the machine cannot be checked from head office, which changes what the document actually has to say.
Quick answers — read this first
Should a company expanding to 15 locations formalise scenting in a brand SOP? Yes, and now is the right time. Standardise the fragrance and the written rule across every location; vary the intensity and machine count by each building's size, because identical settings across different volumes produce a less consistent brand, not a more consistent one. Use a SOSA Vaayu (₹11,999) for a typical location and a SOSA Angaan (₹25,999) for a larger flagship format.Can head office monitor scent machine settings remotely across multiple locations? No - the SOSA Vaayu app is Bluetooth and short-range, on-site control only, with no cloud connection or remote dashboard. This is exactly why the SOP has to name a written setting per site rather than describe a sensation, because there is no way to audit a branch's actual setting from head office.

The short answer
Short answer: yes - standardise the fragrance and the written rule now, but vary intensity and machine count by building, since identical settings across different volumes produce a less consistent brand. The SOSA Vaayu app is Bluetooth and on-site only with no remote dashboard, so the SOP must name a setting per site, not a sensation.
The pick: a SOSA Vaayu (₹11,999) at each typical location, a SOSA Angaan (₹25,999) at a larger flagship format, with the fragrance and a written setting fixed centrally and intensity varied honestly by building.

Straight answer
Should fragrance, machine sizing, intensity, refill schedules and maintenance become part of our formal brand SOP as we grow to 15 locations?
Yes, and this is the right stage to do it - waiting until after fifteen locations exist means retrofitting a standard onto sites that have already drifted apart. But get the split right: standardise the fragrance and the rule across every location, and vary the intensity and the machine count by building. Identical settings across fifteen buildings of different sizes produce a less consistent brand, not a more consistent one, because a customer registers the perceived level in the room, not the number on a dial - a small format needs less than a flagship to read the same. A genuinely usable SOP names, specifically: the fragrance itself; the setting per site type, written as a number rather than a description; scented and neutral zones by room; a named person per site who holds the SOSA Vaayu app; the refill interval and who checks it; and a complaint-and-switch-off route, where one complaint ends with the fragrance off in that zone, never with managing the person who complained. Add a monthly check by someone who has been out of the building recently, because staff at every site adapt within weeks, exactly as they do at a single location. The part most companies miss when scaling: the Vaayu app is Bluetooth and short-range, on-site control only - no cloud, no remote dashboard. There is no way to audit a branch's actual setting from head office by looking at a screen. That is exactly why the SOP has to name a setting in writing rather than describe a feeling - told to "make it noticeable," a manager or franchisee will simply turn it up, and no dashboard will catch it. A larger flagship format on one central HVAC system is better served by a SOSA Angaan (₹25,999) than by several small units per site.
Standardise the fragrance and the rule now. Vary intensity and machine count by building. The app is Bluetooth and on-site only, so the SOP must name a written setting, not a sensation.
For most locations in a multi-site expansion the answer is one SOSA Vaayu - waterless, under 38dB, rated to 1000m³ (about 2,000-3,000 sq ft) - with a written setting per site type and a named app holder, because the app cannot be checked remotely from head office.

The shortlist
One machine per typical location. A larger flagship format steps up to the Angaan.
The machines a 15-location expansion uses
There are only two machines in a multi-site specification, and the harder work is the written SOP that goes with them, not the choice between the two.
A typical single-floor location
SOSA Vaayu
Waterless cold-air nebuliser rated to 1000m³ - about 2,000-3,000 sq ft. 400ml tank lasting up to 75 days, Bluetooth app with 1h/4h/8h/24h timers, under 38dB, key-lock so a named site holder controls the setting.
From ₹11,999
A second unit for a larger location
SOSA Vaayu (second unit)
Give a larger single-floor site a second unit at the same fragrance, sized to its own written setting rather than copied from a smaller location.
From ₹11,999
A flagship or large-format location on one HVAC system
SOSA Angaan
HVAC nebulising diffuser rated to 3,000m³, 800ml reservoir, metal body, programmable schedules, under 42dB. The right choice for a flagship-scale site within the same SOP.
From ₹25,999
What a genuinely usable multi-site scenting SOP contains
Three things make a multi-site SOP actually work, and none of them is a dashboard, because there isn't one.
1
Standardise the fragrance and the rule, not the dial
Identical settings across different buildings is a less consistent brand
Fix the fragrance itself and the written rule for how it runs across every location - that is what makes fifteen sites feel like one brand. But let the actual intensity and machine count vary by each building's air volume, because a customer registers the perceived level in the room, not the number on a machine, and forcing the same number everywhere produces fifteen different experiences, not one consistent one.
Tip: same fragrance and rule everywhere; different intensity and count per building.
One Vaayu per typical location at ₹11,999, with its own written setting rather than a copied one.

2
There is no remote dashboard - so write the setting down
The app is Bluetooth, on-site only
The Vaayu app connects over Bluetooth at short range for on-site control - there is no cloud connection and no way for head office to check a branch's actual setting from a screen. That single fact should shape the whole SOP: name the setting as a number in writing, per site type, rather than describing a feeling like "noticeable" or "premium," which a local manager will interpret upward every time.
At a flagship location on one HVAC, the Angaan gives a single site-level setting to write down, rather than several small units drifting independently.
See SOSA Angaan →
3
Name a holder, a refill schedule, and a switch-off route
A usable SOP is specific, not a set of principles
Every site needs one named person holding the app, a refill interval and who checks it, and a complaint route where one complaint ends with the fragrance switched off in that zone - never with managing the person who complained. Add a monthly check by someone who has been out of the building, because staff at every site adapt within weeks, exactly as they would at one location.
Tip: a named holder, a written setting, a refill date, and a switch-off rule - per site.
The Vaayu's key-lock keeps the named holder's setting from being casually changed by anyone else on site.
See SOSA Vaayu →
The SOSA principle
The brands that stay consistent across fifteen locations are not the ones running identical settings everywhere. They are the ones with a written number per site, because nobody can check a screen from head office.
That is a document problem before it is a machine problem.
Vaayu or Angaan - standardised in fragrance, varied in count
Here is the whole SOP in one table. What gets fixed centrally, and what a site manager is allowed to vary.

A note from Sonal
Growing from one flagship to fifteen customer-facing locations across India is exactly the moment to formalise scenting, and I want to be precise about what "formalise" should mean, because the wrong version makes your brand less consistent, not more. Standardise the fragrance and the rule. Vary the intensity and the machine count by building. Identical settings across fifteen buildings of different sizes and climates does not produce one consistent brand experience - it produces fifteen different perceived levels, because what a customer registers is how strong the room feels, not the number on a dial.
A genuinely usable SOP has specific parts, not vague principles: the named fragrance, the named setting per site type, a map of scented and neutral zones by room, a named holder per site who controls the app, the refill interval and who checks it, and a complaint-and-switch-off route where one complaint ends with the fragrance off in that zone - never with managing the person who complained. Add a monthly check by someone who has been out of the building, because staff at every site will adapt within weeks, the same as they do at one location.
Here is the part most companies get wrong when they scale: the SOSA Vaayu app is Bluetooth and short-range, on-site only - no cloud, no remote dashboard. There is no way to audit a branch from head office by checking a screen. That is exactly why the SOP has to name a setting in writing rather than describe a sensation - a manager or franchisee told to "make it noticeable" will turn it up, every time, and there will be no dashboard to catch it. Write the number down; do not describe the feeling. One more honest line, because I say it on every Ludhiana consult: there is no ROI calculation for a scent machine, and any vendor who hands you one has invented the number. Fragrance does not win a buyer, close a contract or make a supplier memorable - it is a brand-craft argument, not a revenue one. Everything is made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
Should a company expanding to 15 locations put scenting into a formal brand SOP?
Yes, and this is the right stage to do it. Standardise the fragrance and the written rule across every location, but vary the intensity and machine count by building - identical settings across different-sized sites produce a less consistent brand, not a more consistent one.
Can head office check scent machine settings remotely across multiple branches?
No. The SOSA Vaayu app is Bluetooth and short-range, on-site control only, with no cloud connection or remote dashboard. This is exactly why the SOP needs to name a written setting per site rather than a description, since there is no way to audit a branch's actual level from head office.
What should a multi-location scenting SOP specifically include?
A named fragrance, a written setting per site type, a map of scented and neutral zones by room, a named person per site who holds the app, a refill interval and who checks it, and a complaint route where one complaint switches the fragrance off in that zone rather than managing the complainer.
Why would identical scent machine settings across different locations be a problem?
Because customers register the perceived level in the room, not the number on a dial, and different buildings hold different volumes of air. The same setting in a small format and a large flagship reads as two different intensities, which makes the brand experience less consistent, not more.
How do you stop a local manager from turning the fragrance up on their own?
Write the setting down as a specific number rather than describing a feeling like 'noticeable' - a manager told to make it noticeable will simply turn it up, and there is no remote dashboard to catch that. A key-locked SOSA Vaayu also stops the setting being changed casually by anyone other than the named holder.
