Lumen Circle
Light, rooms and what it costs
Free · In‑App Purchases
Make your smart home simple again.
Most smart home apps are crowded with switches, lists and submenus. When you are sitting on the sofa in the evening and want to dim the light, you do not want to tap five lamps one by one first.
That is where Lumen Circle comes in. We have rethought light control from the ground up — away from the technology, towards the person.
YOUR ROOM IN FOCUS
Lumen Circle groups your lighting by room. You no longer control “Floor lamp 1” and “Ceiling light 3”, but simply your “Living room”. Rooms, names and scenes come straight from Apple’s Home app — you set nothing up twice.
THE RING IS THE CONTROL
The heart of the app is the control ring. It replaces countless sliders. One turn or one drag is enough to set the brightness of the whole room in a single flowing move — and every percent clicks into place. Colour and white tone have a sheet of their own, again for every lamp in the room at once rather than lamp by lamp.
LIVE ENERGY USE
Do you actually know what your smart lighting costs in electricity? Lumen Circle makes the draw visible. You see the current wattage in real time and what it does to your bill. It is worked out with curves measured on real lamps; when the library does not know a lamp — with Hue plugs that is the rule — the app says so.
AIR THAT MAKES SENSE
If you have sensors, the app reads them for you. Instead of throwing a bare number like “23.2 degrees” or “1020 ppm” at you, Lumen Circle gives it meaning: “Office: air is poor — window wide open, five to ten minutes.”
TEN PALETTES
We have prepared ten harmonious palettes for you, from Aurora through Graphite to Paper. They set the base tone of the app, not your lamps: the interface stays quiet so the real colours of your light stand out in it. At night the panel switches to a warm profile by itself — no blue light in the bedroom.
ON FOUR DEVICES
The iPad as a wall panel, the iPhone as a remote control, the Apple Watch as a dial and the Mac as a window beside your work. One subscription covers every device with the same Apple ID.
WHAT YOU NEED
A home set up in Apple’s Home app. For the energy meter, a Philips Hue Bridge on the same network as well.
PRICE
Four days free, then CHF 8 a year. The subscription renews automatically for another year each time and can be cancelled at any time in your Apple ID settings.
Download Lumen Circle now and see how simple, how good-looking and how efficient your home can feel.

Ratings & Reviews

Full light is easy to hit again: the ring snaps at 100 percent. Away from home it now says what is actually going on – you are not on Wi-Fi, instead of “The Bridge cannot be reached”. And what you set on one device shows up faster on all the others.
