Hi all
This is the topic for **Lightkeeper**. Questions, bug reports and feature requests are all welcome here 🙂
**Lightkeeper makes the lights and remotes you already have, a bit smarter, without you building any Flows.**
👉 **App Store:** [Lightkeeper | Homey](https://homey.app/a/com.thomassidor.lightkeeper)
🧪 **Test version:** [Lightkeeper | Homey](https://homey.app/a/com.thomassidor.lightkeeper/test)
💻 **Source (MIT):** [GitHub - thomassidor/lightkeeper · GitHub](https://github.com/thomassidor/lightkeeper)
🪲 **Issues:** [Issues · thomassidor/lightkeeper · GitHub](https://github.com/thomassidor/lightkeeper/issues)
> âš **Still taking shape.** This is a 0.x app. An update can change or break a device you have already set up, which may mean running _Repair_ on it or adding it again. Please read the changelog before updating.
## What it does
Add it via **Devices → Add → Lightkeeper** and choose one of five types:
- 🎛 **Light Remote** : turn a remote, switch or dial you already own into a controller for any lights. Lightkeeper writes and maintains the Flows for you.
- ⏰ **Light schedule** : lights on and off at set times on chosen weekdays, with a colour and brightness if you want.
- 🌅 **Circadian light** : warmth through morning, midday and evening, following your own sunrise and sunset.
- 🎨 **Colour Curve Light** : draw the day yourself as points, each with a warmth or a colour.
- 🌤 **Room-sensing Light** : brightness from a lux sensor you already own, or from the sun’s height.
Each device exposes what it wants the lights to be as **Flow tags** , and there are two cards: _Set lights the Lightkeeper way_ and _It is dark enough_.
## Requirements
- **Homey Pro (2023) or newer**, firmware 12.9.0+
- A **Personal API Key** with Flow permissions, but only for Light Remotes and schedules, because Homey doesn’t let apps write Flows on their own. The key stays on your Homey.
Nothing leaves your Homey: no cloud, no telemetry.
## Reporting a problem
Please say which device type it is, which lamp or remote you use, and what the app’s settings page ( **Settings → Apps → Lightkeeper** ) shows. That page lists recent presses and light changes, and why each was acted on or ignored. There’s more in the [FAQ](https://github.com/thomassidor/lightkeeper/blob/main/FAQ.md).

Update: 0.6.5 currently in review.
Changelog:
- **Choose how a device controls your lights** — change them after they turn on (the default), set them before they turn on so they come on already right, or leave them alone and only work out the values. **A device that set colours before lights came on stops doing so until you run the new light test once from Repair.**
- **A remote button can turn lights on the way the rest of the house knows they should look** , taking colour from one Lightkeeper device and brightness from another at the moment you press.
- **Lightkeeper’s values in your own Flows** — as tags, a card that sets a room from two devices in one change, and an _It is dark enough_ condition.
- **Redrawn setup screens** with a new colour picker, colours for schedule blocks, and a shorter Room-sensing Light setup; plus fixes for lights left alone for hours when nobody had touched them, a Light Remote with a colour button arriving unavailable, and a dozen more.
