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 2 minutes (configurable)
- Submits metrics to Datadog via DogStatsD
- Emits Datadog events for state changes (drawer full, offline, errors)
- Supports pet profile metrics (weight, health status)
- Dry-run mode for testing without submitting metrics
- Configuration via environment variables or YAML file
Installation
Using UV (recommended)
# Clone the repository
git clone https://github.com/yourusername/datacat.git
cd datacat
# Install with UV
uv sync
# Run
uv run python -m datacat
Using pip
pip install .

Using Docker
# Build the image
docker build -t datacat .
# Run with environment variables
docker run -d \
-e WHISKER_USERNAME=your-email@example.com \
-e WHISKER_PASSWORD=your-password \
-e DATADOG_API_KEY=your-api-key \
