Modular Touch
4 Vpro

A capacitive four-touch panel that snaps into the plate you already own — and quietly learns the rhythm of the room.

No rewiring, no gateway box, no monthly fee. Mix smart and ordinary modules on the same board, then hand the switch its own clock, its own scenes, and its own sense of when.

Chapter 01 · The swap

One module out. One module in.

A mechanical switch only ever does one thing, and only when a finger is there to do it. The four-touch Vpro panel keeps the same plate, the same wall, the same hole — and changes everything behind the faceplate.

The ordinary module

The rocker you grew up with

  • — A physical lever that only toggles when someone is standing at the wall.
  • — No memory of time — the geyser stays on until a person remembers it.
  • — One switch, one circuit, no relationship to the lights or fan beside it.
  • — Replacing it means new plates, new wiring, and an electrician for an afternoon.

The 4 Vpro way

Capacitive · wifi · keeps your plate

  • ✓ Four touch points that respond to a fingertip — and to a schedule when no one's home.
  • ✓ An on-board clock that runs scenes and timers even when the internet is down.
  • ✓ Snaps into existing ROMA RPro and Vihan VPro plates beside your non-smart modules.
  • ✓ Pick the ON and OFF LED colour, dim the glow, and let Night Mode soften it after dark.
Chapter 02 · From box to wall

Five quiet steps

No new wiring diagram to learn. The panel meets the plate, the plate meets the app, and the room becomes addressable.

Chapter 03 · Two moods of automation

Scenes for the moment.
Schedules for the day.

Some control should happen the instant you walk in. Some should happen whether you're there or not. The 4 Vpro holds both — a single tap that moves a whole room, and a clock that never forgets the geyser.

Chapter 04 · Build a rule, watch it fire

An IF that becomes a THEN

Workflows react to the real world, not the clock. Describe a condition once; the panel and its companions handle the rest, on their own.

22:41:06 workflow › new rule
22:41:07 IF gas sensor detects leak (kitchen)
22:41:08 THEN cut kitchen plug · send WhatsApp alert
22:41:09 IF hallway motion · 23:00–05:00
22:41:10 THEN night light → 5 min, then off
22:41:11 IF bedroom humidity > 70%
22:41:12 THEN dehumidifier on

Chapter 05 · One family, many faces

Pick the module the wall needs

The 4 Vpro is one member of a touch family that all share the same app, the same plate fit, and the same no-subscription promise. Tap a variant to see where it belongs.

Chapter 06 · What sits behind the glass

Six quiet layers

From the fingertip that touches the panel to the rule that runs without you, every press travels the same stack. Tap a layer to read its role.

Chapter 07 · The shape of a rule

Condition, in. Action, out.

Every workflow follows the same four beats — and once it's set, it watches the world so you don't have to.

01 · SENSE

A condition appears

A gas reading, a humidity spike, motion in the hallway — a real-world state, not a clock.

02 · MATCH

The rule recognises it

The IF you wrote once is compared against the live device or sensor state.

03 · ACT

The THEN fires

Plugs cut, lights time out, the dehumidifier wakes — each device with its own parameter.

04 · TELL

You hear about it

A WhatsApp alert lands the moment something needed your attention.

Ask the home a question

Chapter 08 · Answers with receipts

Scoped, grounded, calm

Chapter 09 · Four engines, one panel

What the switch is made of

Behind the capacitive surface, four capabilities work together — each one self-sufficient, none of them asking for a subscription.

🎬

The Scene engine

Combine any switches across any rooms into one named moment. Movie Mode dims four living-room lights to 20%, draws the curtains, powers the TV socket, and stills the ceiling fan — each device with its own setting.

Unlimited devices per scene

⏱️

The Schedule engine

Fourteen ways to give a switch a sense of time: auto-off geyser timers, one-shot countdowns, daily and weekly recurrences, fan-speed and dimmer schedules, and sunrise-to-sunset triggers.

Runs on the switch's local clock

⚙️

The Workflow engine

IF-THEN automations that answer to the real world. IF the gas sensor reads a leak, THEN cut the plug and send a WhatsApp alert. Triggered by device and sensor state, not by the clock.

Reactive, not scheduled

✋

The Touch hardware

Capacitive four-touch sensing rated to 100,000 cycles per point, with app-chosen ON/OFF LED colours, adjustable brightness, and an automatic Night Mode that dims the glow after dark.

Snaps into RPro & VPro plates

Chapter 10 · The wall it joins

Everything it speaks to

The 4 Vpro doesn't ask the room to start over. It fits the plates already on the wall and the modules already in the board.

🔲
Snap-fit

ROMA RPro plates

Drops straight into existing ROMA RPro modular boards — same cut-out, same screw line.

🔳
Snap-fit

Vihan VPro plates

Built for the VPro series board that gives this very module its name.

🔌
Compatible

Anchor · Legrand · GM

And Havells, Schneider, and most Indian switch-plate brands you'll find at home.

🧩
Mixed board

Non-smart modules

Sit smart touch modules beside ordinary ones in the same board — no all-or-nothing.

💬
Alerts

WhatsApp notifications

Workflows reach you where you already are — a leak or a trigger lands as a message.

📡
Inputs

Sensors & sockets

Gas, humidity, and motion sensors plus smart plugs feed the IF side of every rule.

It keeps working when the line goes dark

Schedules and scenes execute on the switch's own clock, so a dropped connection never leaves the geyser running or the morning routine stranded.

Reliability you don't have to think about

A capacitive surface has no lever to fatigue, no contact to pit. Each of the four touch points is rated for a hundred thousand cycles, the LED glow stays app-tunable through Night Mode, and the schedules keep their own time — so the wall behaves the same on day one and year five.

Keep the plate.
Change the wall.

One module swap brings four touch points, scenes, schedules, and sensor-driven workflows to the board you already own — with all twenty app features and nothing to pay each month.
