I’m excited to announce that the Halloween Atmosphere Script has been expanded and renamed to Holiday Atmosphere Scripts!
What’s New in v2.0.0
- NEW: Complete Christmas script with 6 cosy effects
- NEW: Complete New Year script with 5 celebratory effects
- UPDATED: Halloween script with improved Blood Pulse effect
Split into three dedicated scripts for better organization
Improved XY color space handling for maximum compatibility
Hue-safe party mode prevents freezing on older bulbs
Comprehensive documentation with usage examples
The project now includes three dedicated scripts with festive lighting effects for Halloween, Christmas, and New Year’s Eve. All optimized for reliability with older smart bulbs.
