Lightkeeper

Lightkeeper does four things to lights you have already paired. It turns a remote, switch or dial you already own into a controller for them: pick the lights, and say what each press, hold or turn should do. It puts lights on a schedule: when they come on, when they go off, on the days you choose, at a brightness and warmth you set. It follows the colour of the day, either from three parts of the day anchored to your own sunrise and sunset, or from a curve you draw yourself. And it sets brightness from how much light is in the room already, reading a light sensor you own — it shows you that sensor's own last week while you choose — or how high the sun is where you live. Light Remotes and schedules write the Homey Flows for you and keep them maintained, so you never open the Flow editor. Homey does not let an app create Flows on its own, so those two need a Personal API Key with Flow permissions; circadian, Colour Curve and Room-sensing Lights write to your lights directly and need no key. Setting any of the five up is a short numbered path — one question a screen, then a review of everything before it saves. Everything runs on your Homey — no cloud, no telemetry. Designed and written with AI, directed and verified on real hardware.

What’s new

Version 0.6.0 — A fifth kind of device. A Room-sensing Light sets your lights' brightness from how much light is in the room already, dimming them as the morning comes up and lifting them again as it goes — or the other way round if you would rather the room followed the day. It works out how light it is from a light sensor you already own, and most motion sensors have one, or from how high the sun is using your Homey's own location. It needs no API key, only dims lights that are already on, and never switches one on or off. Every setup screen has also been redrawn: one question at a time, and a review of everything before it saves. Circadian lights now describe three parts of the day, with the boundaries following your own sunrise and sunset through the year instead of a fixed clock. On a Light Remote, each button can drive its own lights. Also fixed: a light that quietly returns to its own settings after Lightkeeper changes it is no longer mistaken for you taking over by hand, which could leave that light alone for days. Finally, three device types are renamed: Light controller to Light Remote, Curve light to Colour Curve Light, and Daylight light to Room-sensing Light. Only the names change — devices you have already added keep working, keep the name you gave them, and keep their settings and Flows.
