Installed voice and big-switch home control for people with limited reach
TL;DR Switchless installs and supports home control for people with movement or vision disabilities: voice, a single large switch and a phone fallback for lights, fans, AC, TV and the door. It uses off-the-shelf smart devices, so the product is the assessment, installation and support. Families pay a one-time fee plus a yearly care plan.
Census 2011 counted 2.68 crore disabled people in India, 2.21% of the population, and 20% of them had a movement disability[1]. Among older disabled people, movement disability is the most common type, at 25%[1]. For a lot of them a switchboard placed at shoulder height is a daily barrier.
Mainstream gadgets already help. A wheelchair user quoted in a 2026 report runs his appliances and TV with a voice assistant and smart plugs[2]. But those devices sit outside disability schemes, so there's no subsidy or reimbursement, and they stop working the moment Wi-Fi drops[2]. So families end up buying gadgets that half work, with nobody to set them up or fix them.
What it does, in regulatory terms: consumer home automation, not an assistive medical device. Switchless makes no therapeutic claims, so it should sit outside medical-device rules. Confirm that before advertising.
A trained technician visits, watches how the person moves through a normal day and plans which controls matter - bedside lights, fan speed, the main door, the geyser, a call bell. The kit uses standard smart switches and plugs, with three ways to trigger each action. There's voice, one large push switch mounted where the person can reach it, and a phone app for carers. A small backup router and battery keep it working through short power or internet cuts.
The seed pitched simplified voice activation and I widened it. Voice alone fails for people with speech difficulties and in noisy homes, and voice speakers already exist[3]. What's missing is someone who fits the controls to one person and keeps them working.
The user is the disabled person but the payer is usually the family. They already spend on assistive aids - dedicated vision devices cost ₹3.6–8.1 lakh, and the cheapest AI glasses ₹22,400[2]. A one-time install fee plus a yearly support plan fits that pattern. CSR programmes and disability NGOs are a second buyer, funding installs for low-income users.
A September 2026 report on "incidental accessibility" put mainstream smart devices on the policy agenda, with a government disability official at the launch[2]. The ADIP scheme, which funds certified assistive devices, was revised in September 2024[4]. If consumer devices ever get recognised under such schemes then an installer with records of real outcomes is well placed.
No public figure exists for accessible home-automation spending in India. The narrowest base is 2.68 crore disabled people, about a fifth with movement disability[1]. Only urban families with Wi-Fi and some income are buyers at first, so expect a pool in the low lakhs of households. That's my estimate, so test it.
One Chennai-area startup makes a head-worn controller for hands-free use of computers and smart devices[5]. A big voice-assistant maker has shown its assistant controlling appliances for people with vision and locomotor disabilities at an accessibility museum in Chennai[3]. Neither installs and maintains a whole-home setup. Local electricians fit smart switches all day long but rarely plan around a disability, and that's the gap.
| Difficulty | Moderate (36/100) |
| Starting capital | ₹30–60 L |
| Time to launch | 3–5 months |
The technology is off the shelf. The hard part is service - technicians who understand disability, visits that take two to three hours, and support calls when a device drops off Wi-Fi at night. Margins depend on keeping install time down without losing the personal fit.
No special licence to operate, as long as you stay a consumer home-automation installer and make no therapy claims.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't trust AI to judge a person's abilities or safety. That's the technician's job, ideally with a therapist's input.

Here's what can go south -
I like this one for a founder with occupational therapy or disability-sector experience who can partner with an electrician network. If you want to build hardware then look elsewhere, because the hardware here is the easy, bought-in bit. First prove that 20 installed homes still use the system every day after two months.
Plan for roughly ₹30–60 L. The hardware is bought in, so most of it goes on trained technicians and support.
No special licence if you sell home automation and make no therapy claims. Use licensed electricians for wiring and take DPDP consent for voice data.
Yes, the need is universal. Check whether your country's disability schemes fund such devices and how its medical-device rules treat them.

Thinking about building Switchless or something close to it? The make-or-break work is keeping installs personal while making the service pay for itself, and that's a balance I enjoy working out with founders. If you need a hand, you know where to find me. Talk to Yash →
