**Your OnlyCat cat flap in Homey: which cat came in, what it was carrying, and why one was turned away.**

### 🐈 What it does

- **See which cat, by name.** Every cat becomes its own sensor, under the name you already gave it. Flow cards take _any cat_ or a specific one.
- **Get the photo, not just the alert.** Every trigger carries a snapshot, so a prey warning arrives as an actual picture.
- **Know why a cat was turned away.** The app works out which of your door rules refused her and says so in words. When the flap’s own sensors mean it cannot tell, it says that instead.
- **Watch the clip.** The last event’s video and still frame, on the device.
- **Automate the door.** Curfew at sunset, keep everyone in while it is raining, lock both ways when the wind picks up. Unlocking is the tile’s quick action.
- **Track the trends.** Times in and out, refusals, prey attempts, who is home, and how long each cat has been outside, all in Insights.

### 🔑 Getting started

1. Install [the app](https://homey.app/a/com.onlycat.cloud/).
2. In the OnlyCat app, go to _Account → Developer Mode → API Keys_ and create a key.
3. Start pairing, add your flap and paste the key.

⚠ The key has full access to your OnlyCat account and cannot be limited. Make one just for Homey, so you can revoke it on its own later.
