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.
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.
Solar monitoring
Solvane
Plug-in logger for your inverter
A small box that wires to your existing inverter and puts what it is
doing on your phone — generation, load, battery, and what the grid
is costing you.
Fits Deye, Growatt, Luminous, Microtek and more
Works with the solar you already own
Set up on your own wi-fi in a minute, no app store
Updates itself, so it gets better after you buy it
Every unit is assembled and bench-tested against a real inverter or a
real room before it is boxed. Dispatch
within 7 days, Blue Dart or Delhivery, tracked.
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?
☀️ Generation, house load, battery and grid — live
💰 Savings priced on your own state's tariff, not an average
🔔 Told when a string drops out, before the bill tells you
your solar, right now

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.
route 4 · this morning

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
The shaded band is the learned ordinary. Fictional data.
thursday · 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.
right now
In bed 22 minutes. Fictional data.
last night · 22:00 to 06:00
Asleep 7h 20m, two restless spells. Fictional data.
resting heart rate · 30 nights
The slow drift is the point — no single night shows it. Fictional data.
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.
