Our technology
The hardware, the materials
and the thinking behind them.
Smart Climate is a small family of objects and one decision layer that connects them. This page goes through each device, what it is made of, and how the system decides what your home should do next.
The hardware
Five objects.
One climate.
Smart Climate is designed as a family: machined aluminium, woven textile, one seam, no screens. Objects that belong in a Nordic home rather than a server rack — and that disappear once installed.
01 / 05
Climate Hub
The quiet intelligence of the house.
The Hub holds the model of your home. It reads every sensor, forecasts the next few hours of weather and sun, and decides what should move — heating, ventilation, windows, shading — before you would have thought to ask.
- Processor
- Quad-core edge compute, on-device inference
- Radio
- Thread · Zigbee 3.0 · Wi-Fi 6 · Bluetooth LE
- Power
- Mains, 4.5 W typical · 72 h battery backup
- Materials
- Anodised aluminium, woven acoustic textile
- Finish
- Natural silver · Warm grey · Graphite
- Dimensions
- 132 × 96 × 38 mm · 610 g
Works with — Every Smart Climate device. Matter, HomeKit, Google Home.
02 / 05
Room Sensor
One disc. Four kinds of awareness.
Placed on a shelf or set flush to the wall, the sensor measures what a room actually feels like — not what the thermostat in the hallway assumes. Temperature, humidity, CO₂ and daylight, sampled every thirty seconds.
- Sensing
- Temperature ±0.2 °C · RH ±2 % · CO₂ NDIR · Lux
- Sample rate
- 30 s · adaptive to 5 s during transitions
- Radio
- Thread, mesh-forming
- Power
- Rechargeable cell, 24 months per charge
- Materials
- Machined aluminium ring, perforated textile
- Dimensions
- Ø 68 × 17 mm · 96 g
Works with — Climate Hub. One per room recommended.
03 / 05
Window Actuator
Fresh air without a decision.
A chain actuator that retrofits to existing roof and façade windows. It opens in millimetre increments, so the house can ventilate through the night without ever feeling draughty — and closes itself when rain or wind arrives.
- Stroke
- 0–300 mm, 1 mm resolution
- Force
- 300 N push · 300 N pull
- Acoustics
- < 42 dB(A) at 1 m
- Safety
- Obstruction detection · rain and wind auto-close
- Materials
- Extruded anodised aluminium, steel chain
- Dimensions
- 412 × 32 × 26 mm
Works with — Most roof and façade windows from 2005 onward.
04 / 05
Heating Control
Every room, its own climate.
A radiator head that turns a single-zone house into a room-by-room system. It learns how quickly each room heats and cools, then heats ahead of you rather than reacting after you are already cold.
- Control
- Predictive, per-room learning curve
- Valve
- M30 × 1.5 · adapters for RA, RAV, RAVL, Danfoss
- Radio
- Thread, mesh-forming
- Power
- 2 × AA lithium, 24 months
- Materials
- Anodised aluminium barrel, knurled steel ring
- Dimensions
- Ø 52 × 84 mm · 210 g
Works with — Radiator systems. Underfloor via the zone module.
05 / 05
Shading Control
Sunlight, managed before it becomes heat.
The quietest device in the system, and often the most effective. It lowers blinds and awnings ahead of solar gain, so the house never needs cooling in the first place — the difference between comfort and air conditioning.
- Channels
- 4 shading groups per module
- Inputs
- Solar forecast, façade orientation, room load
- Radio
- Thread · dry-contact and RTS bridging
- Power
- Mains, 1.8 W typical
- Materials
- Recycled polymer face, aluminium bracket
- Dimensions
- 94 × 54 × 24 mm
Works with — Internal blinds, external awnings, shutters.
Materials
Anodised aluminium
Machined from a single billet, anodised rather than painted, so the surface ages instead of chipping.
Woven textile
A dense Danish weave chosen for acoustics and for how it reads in a living room — warm, matte, unbranded.
Recycled polymer
Bone-white, 78 % post-industrial content, tuned to a soft-touch grain that hides fingerprints.
Behind Smart Climate
Years of home-climate expertise.
One new idea.
Smart Climate brings together expertise across windows, indoor climate, heating, ventilation, software and intelligent control. The technology has been developed and tested in real homes by specialists working at the intersection of buildings and technology.
Developed by an innovation team from VELUX together with specialist technology partners
One decision layer.
Many possible connections.
Smart Climate combines live information from your home with external conditions to continuously decide the most efficient way to maintain your indoor climate.
No schedules to constantly adjust. No separate systems fighting each other. One home. Acting together.
