Lightkeeper

Lightkeeper does three 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. And it follows the colour of the day, either from two settings — how warm, how cool — or from a curve you draw yourself. Light controllers 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 and Curve lights write to your lights directly and need no key. Everything runs on your Homey — no cloud, no telemetry. Designed and written with AI, directed and verified on real hardware.
