Designed and built in India

Solar you can see. A home that pays attention.

We install solar, and we build the intelligence that sits on top of it — energy you can read at a glance, rooms that know someone is in them, and a house that looks after the people inside without watching them.

Five for the home. One for schools.

Start with the one that solves today's problem. They work alone, and they work better together — the same app, the same login, whether you own one or all four. Schools have their own platform: Vidyara.

Presence & automation

Aurenn

Rooms that know you are there

Not a motion sensor. Aurenn senses a person the way radar does — it can tell that someone is sitting perfectly still, reading, or asleep.

  • Lights that never switch off on a still person
  • Knows how far into the room you are, not just that you moved
  • Works in the dark, and through steam or glare
  • No camera, no microphone, nothing recorded

Sentivo

Home and office watch

Learns the faces that belong. A familiar arrival is logged quietly; a stranger who stays is escalated, with the clip already waiting for you.

  • Tells family and staff apart from a stranger
  • Alerts once, with the picture — not forty times a night
  • Everything recorded stays on your own hardware
  • Runs on the cameras you have

Why it matters
Contactless vitals

Nyvra

Breathing and heart rate, from across the room

A 60 GHz radar above the bed reads the rise and fall of a chest and the beat underneath it. Nothing worn, nothing charged, nothing touching them.

  • Breathing rate and heart rate while they sleep
  • Detects a fall, and says so immediately
  • No wearable, no pendant, no camera
  • Wellbeing monitoring — not a diagnosis

Solvane · Solar monitoring

Most people never find out what their solar actually did.

The inverter has the numbers. It just keeps them behind a screen on a wall in a cupboard. Solvane reads them every minute and turns them into the one thing you wanted to know: is it working, and what did it save me?

Aurenn · Presence sensing

Your lights go off while you are still in the room. That is a sensor problem.

The sensors in most homes and offices detect movement. Sit still for two minutes — reading, eating, watching something — and as far as they are concerned the room is empty. Aurenn detects a person.

An ordinary motion sensor

Watches for a warm thing moving across its view. It sees you arrive, then loses you the moment you settle. It cannot tell how far away you are, struggles in heat, and gets fooled by a curtain.

Aurenn

Reads the room the way radar reads the sky — bounced radio, not body heat. It holds on to a person who is sitting perfectly still, knows how far into the room they are, and does not care whether the light is on.

Still means present

Read a book for an hour. The light stays on. That is the whole point.

Distance, not just motion

Knows someone is at the door versus across the room, so a rule can be about where you are.

Nothing is watching

No lens, no microphone, nothing stored. It knows a person is there. It does not know who.

Sentivo · AI security

An alarm nobody trusts is not security.

Most systems shout at every passing cat until the family mutes them. Sentivo learns who belongs — family, staff, the regular delivery — and stays quiet for them. It speaks up for a stranger who lingers, once, with the picture already attached.

  • 🎯  Alerts on strangers, not on people
  • 🏠  Recordings stay on your hardware, not our cloud
  • 🚪  It never opens your gate. That stays yours.
Vidyara · For schools

A parent's two questions: did she get in, and where is the bus?

Everything else a school runs on — fees, payroll, admissions, report cards — matters to the office. Those two questions matter to four hundred families every single morning, and most schools answer them with a phone call. Vidyara answers them before anybody asks.

Attendance at the gate

Face, card or fingerprint as they walk in — with the time, the gate, and how certain the match was. A parent knows their child arrived without ringing the office.

Boarded and alighted

Not just where the bus is — which child got on it, at which stop, and whether they got off at the right one.

The office side too

Fees and invoicing, payroll, admissions, report cards, vendors — one system rather than six, each school switching on only what it uses.

Built for two people at once

You want the data. They want to be left alone.

The same house, two completely different needs — and most products only serve one of them. Ours are designed so the person who buys it and the person who lives with it both get what they wanted.

If you are buying it for yourself

Everything, on your phone, right now.

  • Live figures, real history, and charts that actually load
  • Rules you write yourself — lights, fans, the geyser
  • Your data is yours; export it, or run the whole thing on your own box
  • Buy one product, add another later, same login
If you are buying it for your parents

Nothing for them to learn. Nothing to charge.

  • No app they must open, no button they must press
  • No wearable to forget, no pendant to refuse to wear
  • No camera in a bedroom — presence sensing does not have a lens
  • You get told when something is off. Otherwise you are both left in peace.
Cardyn · What you would actually see

Most days it has nothing to say. That is the product working.

Cardyn learns which rooms get used, and when, over a few weeks. It is not watching for an event — it is noticing when an ordinary morning does not arrive.

tuesday · nothing to report
0609 1215 1821 Within the usual range · 14th quiet day
The shaded band is the learned ordinary. Fictional data.
thursday · 09:24
0609 1215 1821 Kitchen unused. Usually in by 07:10 — it is 09:24.
One message, once. Fictional data.

What it is not: Cardyn does not detect falls, and nothing on this page should be read as saying it does. It reports that a room went unused, and leaves the conclusion to the person who knows the household.

Nyvra · Contactless vitals

It reads a chest rising and falling from four feet away.

A 60 GHz radar over the bed measures the movement of a chest wall — the slow swell of a breath, and the far smaller push of a heartbeat underneath it. No contact, no wearable, nothing for them to remember. Three time scales, because a single number tells you almost nothing.

Nothing worn

No band, no pendant, no charging. The one class of device an elderly parent cannot refuse to put on.

A fall, said immediately

A second radar module watches for a fall and raises it at once, rather than waiting for the next quiet hour to look odd.

Trends, not alarms

A resting heart rate creeping up over a week is the kind of thing a doctor wants to hear about. Most of what this finds is boring, and that is correct.

What Nyvra does not measure

Blood oxygen, blood pressure, blood sugar and body temperature are not on this list, and never will be. Radar measures movement. Oxygen saturation needs light passed through tissue; glucose and blood pressure have no validated contactless method at all. Any product claiming them from across a room is claiming something the physics does not permit.

Nyvra is a wellbeing monitor, not a diagnostic instrument, and not an ECG. It is for noticing that something has changed and telling a person who can act. It is not for deciding whether to call an ambulance — make that call.

Getting started

Three steps, and none of them involve a manual.

01

It arrives

Built and tested to order, dispatched within 7 days. Wire it to your inverter, or we fit it.

02

It asks for your wi-fi

The box makes its own network. Join it from your phone, pick yours, type the password once.

03

Scan the label

There is a code on the underside. Scan it, and your system appears. That is the whole setup.
