- Add activity history collection for cat usage events - Add insight metrics (total cycles, average cycles, cycles today) - Add cat usage events with weight for LR4 - Add intermediate state events (cycle started, cycle complete, etc.) - Add pet visits_24h metric from weight history - Add new LR4 metrics: lifetime_cycles, dfi_trigger_count, cat_detected - Add configurable activity lookback window to prevent duplicate events - Add API call delays to avoid rate limiting - Update default poll interval to 5 minutes - Update documentation with new metrics and events

# Datacat
|
|
|
|
Collect metrics from Whisker Litter Robot devices and submit to Datadog.
|
|
|
|
Datacat connects to the Whisker API (used by Litter-Robot and Feeder-Robot devices) and periodically collects metrics, submitting them to Datadog for monitoring and alerting.
|
|
|
|
## Supported Devices
|
|
|
|
- **Litter-Robot 3** - Original connected litter box
|
|
- **Litter-Robot 4** - Newer model with additional sensors
|
|
- **Feeder-Robot** - Automatic pet feeder
|
|
|
|
## Features
|
|
|
|
- Collects metrics from all connected robots every 5 minutes (configurable)
|
|
- Fetches activity history to detect cat usage events
|
|
- Collects insight data (cycle counts, daily averages)
|
|
- Submits metrics to Datadog via DogStatsD
|
|
- Emits Datadog events for state changes (cat usage, drawer full, offline, errors)
|
|
- Supports pet profile metrics (weight, health status, visit count)
|
|
- Dry-run mode for testing without submitting metrics
|
|
- Configuration via environment variables or YAML file
|
|
|
|
## Installation

```bash
|
|
# Clone the repository
