06:20 · Morning scene — all by itself
The kitchen comes on in warm white and the blinds let in the first sun. You set the Morning scene once.
The kitchen comes on in warm white and the blinds let in the first sun. Nobody pressed anything — you set the Morning scene as the default for the early hours once, and that was it.
08:10 · nobody home
The last one out closes the door — and every light switches itself off. The blinds keep watching the sun.
The last person closes the door behind them and every light switches itself off. Meanwhile the blinds keep watching the sun: the slats tilt to exactly the angle that stops the direct beam — the view stays.
17:30 · the default scene for early evening
You are back and the kitchen switches to the Cooking scene. Every time of day has a default scene; BARAQ switches it itself.
You are back and the kitchen switches to the Cooking scene — spots aim at the worktop, the LED strip under the cabinets shifts to amber. No flood of white. And no magic: you assigned a default scene to each time of day and BARAQ switches them itself. You can change anything by hand, any time.
20:50 · one touch on ioSWIPE
A tap on the Movie pad: TV backlight to blue, lamps dimmed, blinds drawn. Four scenes live right on the switch.
A tap on the Movie pad: TV backlight to blue, lamps dimmed, everything else off. It is getting dark outside, so the blinds draw the privacy themselves. Four favourite scenes live right on the switch.
23:05 · a palm on the switch
A palm on the glass and the room falls asleep: lights to a night minimum, blinds blacked out. The guide light stays on.
Hold your palm on the glass and the room falls asleep: the lights fade to a night minimum, the blinds black out. On the edge of the switch the guide light stays lit — a quiet little night lamp that sees you through the dark.

06:40 · Morning scene
The lights come up at a warm 2,700 K with low brightness — no cold jolt first thing. The day brings the brightness.
Coffee is brewing and the lights come up at a warm 2,700 K with low brightness — no cold jolt first thing. Outside, dawn is just breaking; the day will bring the brightness, the house simply meets it halfway.
09:30 · Work scene
The work corner gets brighter and shifts to a neutral white around 4,700 K.
The work corner becomes brighter and shifts to a neutral white around 4,700 K. Adjust the lighting to the task at hand.
13:00 · sun at its highest
At noon, daylight is at its coolest and strongest. The window plays the lead, the fixtures just fill in.
At noon, daylight is at its coolest and strongest — the window plays the lead, the fixtures just quietly fill in. This is exactly the curve the Light by time of day rule follows.
16:20 · homework after school
The desk light stays bright for homework while the rest of the room dims into the evening scene.
Afternoons at the desk are for homework. The desk light stays bright while the rest of the room gradually dims into the evening scene.
18:40 · Hobby scene
The room settles into warm white; the lamp over the model keeps a neutral island. The scene follows the activity.
The room settles into warm white, but the lamp above the unfinished model keeps a neutral island — colours and details need to be seen. The scene follows the activity, not just the clock.
20:40 · Gaming scene
The room stays softly warm while you play. Screen brightness is set separately.
The room stays softly lit with warm light while you play. Adjust screen brightness separately — room lighting alone cannot remove a screen’s effect on sleep.
22:10 · Reading scene
Amber 2,200 K, tea and a few pages. Light that doesn't argue with the body when it says the day is over.
Amber 2,200 K, tea and a few pages. No grand gesture — just light that doesn't argue with the body when it says the day is over.
23:30 · good night
Darkness for sleeping, only an orange trace by the switch. In the morning it starts again — by itself, on the same curve.

Morning light sets the clockThe body clock is driven mainly by light and dark. Morning daylight helps the body recognise the start of the active day — in the evening, light should be dimmed instead.

Winter · 05:00 · −7 °C outside
Using the ioMETEO forecast, the house works out when to start so the living room is at 22 °C by six.
Using the forecast from the ioMETEO weather station, the house works out when to start so the living room is at 22 °C by six in the morning. Water at 35 °C flows through the floor — and only into the loops where heating makes sense right now.
06:10 · living room · 21.6 °C
ioSWIPE measures temperature, humidity and CO₂ right where you live. It reports over the bus: two wires, no batteries.
ioSWIPE is more than a switch — it measures temperature, humidity and CO₂ right where you live. Every change is reported over the babus bus: two wires, no Wi-Fi, no batteries in wall boxes.
06:10 · distribution board · three modules
ioMASTER compares the readings against the heating plan and, via ioRELAY, switches exactly the loop that should heat.
In the board, ioMASTER compares the readings against the heating plan and, through ioRELAY, switches the actuator of exactly the loop that should heat. No magic — a relay that quietly clicks, and warm water flows into the bathroom loop.
06:30 · five loops, five temperatures
Bathroom 23 °C, bedroom 18 °C, living room 22 °C. Water flows only where it is needed. Every degree down is roughly 6 % of the energy.
In the morning the bathroom holds 23 °C, the bedroom sleeps at 18 °C, the living room sits at 22 °C. Each underfloor loop has its own actuator — water flows only into the rooms that need it right now. And every degree down is roughly 6 % of the energy.
17:30 · heating scenes
Frost guard 5 °C, Setback 17 °C, Work 19 °C, Comfort 22 °C. The weekly plan switches them for each room separately.
Heating scenes work like lighting scenes: Frost guard 5 °C, Setback 17 °C, Work 19 °C, Comfort 22 °C. The weekly plan switches them for each room separately — and you only rarely reach for plus and minus.
July · 14:00 · 33 °C outside
The blinds stop the sun, the heat pump reverses and water at 18 °C flows through the floor. The zones still apply.
The blinds stop the sun before the glass, the heat pump reverses, and water at 18 °C flows through the floor. The zones still apply — the bedroom is pre-cooled for the night, the bathroom is skipped because of the dew point. For a quick top-up the house calls in the air conditioning.
And how much does it save?
Public sources cite roughly 5–10 % for well-tuned control with setbacks. We won't promise a specific amount.

ioSWIPE holds three paths: the RS-485 bus, Wi-Fi and Bluetooth. Wire a sensor straight to the ioSWIPE.
ioSWIPE holds three paths at once: the wired RS-485 bus, Wi-Fi and Bluetooth. Plus a physical input — wire a sensor or a button straight to the ioSWIPE, with no cables pulled back to the cabinet. Wireless sensors nearby report to it directly.
Under the lens · ioMULTISENS
Motion, sound and light in one Ø 52 mm puck — ceiling, shelf or terrace. It sits on the same cable as the switches.
Ø 52 mm, 40 mm mounting hole: motion, sound and light (PIR · MIC · LUX), IP44 rated — into the ceiling, onto a shelf, out on the terrace. It sits on the same cable as the switches and, like ioSWIPE, acts as a gateway: a physical input, Wi-Fi and Bluetooth.

A greenhouse grew behind the house: tomatoes, herbs, lettuce — and a wireless moisture sensor at every plant. Over radio they report to the gateway in the switch, and the house opens drip irrigation only where it is truly dry: today the tomatoes drink, the lettuce waits. Wired sensors are still served by the physical inputs and ioINPUT (16×).
