“Smart home” has come to mean an app, a Wi-Fi account and a hub that stops working when the internet does. It does not have to. Every upgrade on this list runs on plain 220V mains, costs under Rs 2000, installs in under an hour, and keeps working during load shedding, during an internet outage, and ten years from now when the app has been discontinued.
Which one for which room
1. E27 motion sensor bulb holder — the no-rewiring one
Rs 950. Start here if you have never done any of this. It is a bulb holder with a PIR sensor built in: two wires to your existing lamp point, screw in any E27 bulb, and that light is now automatic. No switch, no third wire, nothing in the wall.
It is the obvious answer for store rooms, garages, basements, back yards and staircases — anywhere the switch is at the wrong end of the room. Comes in Z04-N Fixed and Z04-Q Adjustable; buy the Q if it is for a staircase so you can lengthen the hold time.
2. Type-86 motion sensor wall panel — the invisible one
Rs 950. This replaces an ordinary wall switch in the 86×86mm box that is already there. Ten minutes, no new holes, and the room looks unchanged — just a flat white plate with a small lens instead of a rocker.
Best at entrances, on stairs and in bedrooms, where people arrive from a predictable direction. See it here.
3. Recessed ceiling motion sensor — the 360° one
Rs 2000. Mounts flush in the ceiling like a small downlight and covers the entire room, not just one cone. Because it looks down rather than across, it does not have the blind spots a wall sensor has.
This is what you want in a corridor with doors on both sides, a bathroom, or an office. It needs a cut-out and a cable run, so it makes most sense where the ceiling is already open. See it here.
4. Adjustable PIR wall sensor — the outdoor one
Rs 1250. Surface-mounted with a swivel head, so you can aim the detection zone exactly where you want it: down a driveway, along a boundary wall, across a gate. That aiming is the whole point — a fixed sensor covers whatever it happens to face, which outdoors is rarely what you need.
Pair it with an LED flood light and you have a security light that only runs when something is actually there. See it here.
5. Photocell day/night sensor — the dusk-to-dawn one
Rs 400. The cheapest item on the list and the one with the clearest job: it turns a light on at dusk and off at dawn, permanently, with nothing to set. Gate lights, boundary lights, shop signs and street lights all want this rather than a motion sensor, because they should stay on all night.
Do not confuse it with a motion sensor — this one does not care whether anyone is there, only whether it is dark. See it here.
6. 63A voltage & current protector — the one that protects everything else
Rs 2000. Not lighting, but easily the highest-value item here. It sits on the DIN rail after your main breaker, watches the incoming supply, and cuts power to the whole board when the voltage goes too high or too low or the current goes too high — then reconnects itself once things are stable.
In an area with an unstable supply, this is what stands between a voltage swing and your fridge, AC, TV and computer. See it here.
What this costs and what it saves
| Upgrade | Price | Install effort |
|---|---|---|
| Photocell day/night sensor | Rs 400 | Three wires, 15 minutes |
| E27 sensor bulb holder | Rs 950 | Two wires, no switch needed |
| Type-86 wall panel | Rs 950 | Swap the existing switch |
| Adjustable PIR wall sensor | Rs 1250 | Surface mount, three wires |
| Recessed ceiling sensor | Rs 2000 | Needs a ceiling cut-out |
| 63A voltage protector | Rs 2000 | Electrician, at the board |
A sensible starting point for most houses is the staircase and the store room — two E27 holders, Rs 1900, and those two lights never get left on again.
Do it in this order
- Start with the light that gets left on most. Usually a staircase, a store room or a back yard. One E27 sensor holder.
- Then the outdoor light — photocell if it should be on all night, adjustable PIR if it should only come on for people.
- Then the rooms with existing switches — Type-86 panels, one at a time.
- Then the protector, when the budget allows, because it protects everything else you own.
What we deliberately left off
Wi-Fi smart switches and app-controlled bulbs. They are fine products and we stock some of them, but they are a different decision: they need a working router, an account, and a company that stays in business. Everything on this list is a piece of hardware that does one job and keeps doing it. Start here, add the connected stuff later if you want it.
Frequently asked questions
Do any of these need an app or internet?
None of them. They are all mains-powered devices with physical adjustments on the body.
Can I install these myself?
The E27 holder and the photocell are simple two- and three-wire connections that a careful person can do with the breaker off. The ceiling sensor and especially the voltage protector should be done by an electrician.
Will motion sensors work with LED bulbs?
Yes, and it is the best pairing — LEDs draw so little that the sensor’s load rating is never a concern.
Do these save enough electricity to matter?
For lights that genuinely get left on for hours — staircases, corridors, store rooms, outdoor lights — yes. For a room you are sitting in anyway, no. Target the forgotten lights.
