PySrDaliGateway 0.20.4

Python library for Sunricher DALI Gateway (EDA)

PySrDaliGateway

Python library for Sunricher DALI Gateway (EDA) integration with Home Assistant.

Features

• Async/await support for non-blocking operations
• Device discovery and control (lights, sensors, panels)
• Group and scene management
• Real-time status updates via MQTT
• Energy monitoring support
• Full Type Support: Complete type hints for mypy, Pylance, and pyright
• IDE integration with auto-completion and error checking

Installation

pip install PySrDaliGateway

Device Types Supported

• Lighting: Dimmer, CCT, RGB, RGBW, RGBWA
• Sensors: Motion, Illuminance
• Panels: 2-Key, 4-Key, 6-Key, 8-Key

Requirements

• Python 3.8+
• paho-mqtt>=1.6.0

Testing

Hardware integration tests use pytest with real DALI gateway hardware.

Setup

pip install -e ".[dev]"

Running Tests

# Run default tests (excludes destructive and slow tests)
pytest tests/

# Run all tests including slow (bus scan) tests
pytest tests/ -m ""

# Run only bus scan tests
pytest tests/ -m slow

# Run only destructive tests (e.g. gateway restart)
pytest tests/ -m destructive

# Run a specific test file
pytest tests/test_devices.py -v

# Limit device iterations for faster testing
pytest tests/ --device-limit 3

Gateway Connection

Tests connect to a real gateway using one of three methods (in priority order):

1. CLI parameters — provide credentials directly:

   pytest tests/ --direct-sn GW123456 --direct-ip 192.168.1.100 \
     --direct-username admin --direct-passwd password123
   

2. Credential cache — reuses credentials from a previous session, stored in tests/.gateway_cache.json

3. UDP discovery — auto-discovers gateways on the local network

Test Markers

Marker	Default	Description
destructive	skip	Tests that disrupt gateway state (e.g. restart)
slow	skip	Long-running tests (e.g. bus scan >30s)
