Key Features

Source: GitHub README

Readable DSL → write logic like natural language (if motion && lux < 50 then light = on)
Sync devices → keep switches, dimmers, and fans perfectly in sync
Schedules → declare time-based gates (enable from 08:00 until 19:00)
Weekday/weekend/holiday schedules → full support for Home Assistant’s Workday integration (v0.4.0)
Loop-safe → context ID tracking prevents feedback loops
Per-rule enable gates → disable rule or enable rule dynamically
Inline waits → wait (!motion for 10m) works like native HA triggers
Color temperature in Kelvin → light.kelvin = 2700
Modular packages/imports → split automations across files with public/private exports
Auto-reload resilience → schedules re-evaluate automatically on HA restart
