Heliostat One Base

Some rooms never see the sun. So we move the sun.

Every home has them: the north-facing living room that stays grey at noon, the reading corner that's beautiful but dim, the kitchen that only feels alive for twenty minutes a day, the terrace seat the sun abandoned an hour ago. You can't move the house. You can't move the sun.

Heliostat One Base moves the sunlight instead.

It's a precision sun-tracking mirror that follows the sun across the sky and steers a steady beam of real, warm daylight exactly where you want it — a wall, a chair, a breakfast table, a favourite plant. You set the target once in the app. From sunrise to sunset the Base quietly re-aims itself so that spot stays bathed in genuine sunlight — not a lamp pretending to be one. As the seasons shift and the sun's path changes, it keeps following, year after year.

This isn't smart lighting. It's actual sunlight — the light that lifts your mood, warms a room without touching the heating bill, and makes a space feel alive — delivered to the places architecture forgot.

What you'll actually use it for

• Wake up a dark room. Aim a warm pool of daylight onto the wall or floor of a north-facing or shaded room and watch it transform from cave to living space.
• Build a sun-trap on demand. Put the afternoon sun back on your terrace chair or garden bench after the building line has stolen it.
• Light a moment, on schedule. A sunlit breakfast nook at 7:30, the reading chair lit at 16:00 — set daily profiles and let it run.
• Keep plants and people happier through winter. Direct real daylight to indoor plants, or to the spot where you have your morning coffee, when the low winter sun would otherwise miss the room entirely.
• Make a quiet design statement. A beautifully machined, slow-moving instrument that does something no lamp can. Guests will ask about it.

How it works (the engineering, for the people who care)

The Base is a moving-head, two-axis instrument milled from anodised aluminium (AlSi10Mg). An astronomical algorithm computes the sun's exact position locally and drives self-locking geared NEMA motors to keep a Ø420 mm low-iron glass mirror (>92% reflectivity) pointed at your chosen target.

• Pointing accuracy: repeatability < 0.05° — it hits the same spot every time.
• Range of motion: 540° of rotation (±270°) and full −90° to +90° tilt.
• Built for outdoors: IP65-sealed against dust and driving rain, rated −20 °C to +60 °C, stable in winds up to 12 m/s with an automatic storm-park above that.
• Runs itself: on-board LiFePO4 battery buffer (~43 h autonomy) and an included IP44 USB-C PD power supply.
• Control: free iOS & Android app over your local Wi-Fi. Manual joystick aiming, two favourite positions, astronomical auto-tracking, weekly schedules — no account, no cloud required.
• Size & weight: under 660 mm tall, ~16–18 kg, on a Ø320 mm base. Mounts via a universal flange to a ground anchor, wall bracket or mast (sold separately).
• Upgrade-ready: the tool-free Twist-Dock interface lets you click on the Pro-Module later in under 30 seconds — no tools, no rewiring.

Why you can trust it

• Glare protection that can't be switched off. The Base ships with a built-in, camera-free fail-safe: angle-based exclusion zones plus an automatic park position, running on the same proven motion logic that tracks the sun. Safety isn't a paid add-on.
• No camera. None. The Base has no camera and no microphone at all — nothing to hack, nothing to cover, nothing to worry about.
• Engineered to the right standards. Designed and built to meet EN 62471 (photobiological safety, target Risk Group 1 — no focal "spot," by design), EN 62368-1 electrical safety, EN 60529 IP65, and EMC/radio norms; full CE and FCC compliance is in process ahead of shipping.
• German-engineered, serviceable, built to last. A combined service is recommended only once every two years, and the battery/electronics are reachable through a service hatch without breaking the weather seal.
• Honest about where we are. Heliostat One is in its founding pre-launch phase. We tell you exactly what's certified, what's underway, and what your reservation does — in plain language, on the product page.
