Design concept of the Kaelion unit: a small graphite box on an oak surface, the orbit mark lit on top.

System · in development

How Kaelion works in your home.

A small unit next to your devices. It measures the home, plans ahead, controls only what you allow — and then measures what actually happened.

Runs locally in your home
Control does not need a constant cloud connection
Control is off until you switch it on

Design concept — not final hardware

One system

Your home’s energy, in one picture.

Kaelion sits in the middle. Around it: what it reads, and the one device it controls today.

Online. Prices and forecasts arrive over the internet; everything else stays in the home. Offline. Measuring and control stay in the home. Without fresh prices or forecasts Kaelion does not guess: it falls back to safe behaviour until they return.

The loop

Measure. Plan. Control. Measure again.

1
Measure
Consumption, solar, battery, grid and temperatures, read from the devices in your home.
2
Plan
Tomorrow’s prices and the weather forecast, set against what the home needs. One plan for all devices.
3
Control
Only devices you have enabled, and only within your limits. Every command is checked first.
4
Measure again
What actually happened, compared with a baseline. Only the proven difference counts.

The whole cycle runs on the unit in your home. Details of each step: an illustrated day

Safe control

Every command passes the same checks.

Kaelion is built to hold back rather than act blind. When something is not right, it stops — and shows you why.

Try a situation

Plan: charge the battery 02–05

Enabled by youControl is switched on for this device.
Trusted connectionThe link to the device is commissioned and trusted.
Fresh dataReadings are recent enough to act on.
Within your limitsThe command stays inside the limits you set.
Not too oftenCommands are rate-limited.

Sent · result recordedHeld back · reason shown

All five checks pass. The command is sent, and its result is recorded so you can see what happened.

Control can also run as a dry run: Kaelion shows what it would do, without doing it. The plan above is an illustration.

Where it stands

Designed for the whole home. Proven one part at a time.

Being part of the architecture is not the same as a verified saving. A part is shown as verified only after it has been measured against a baseline in a real home.

Status by part of the home
	Measured	Controlled	Saving verified
Battery	yes	yes	yes	Active in the test home. The saving is measured against a baseline.
