CAFE (Complex Automation Flow Editor) for Home Assistant is an innovative automation authoring tool that provides a visual flow editor inside Home Assistant, offering a “third way” between manual YAML and external flow tools by transpiling visual flows directly into native Home Assistant automation YAML. It’s designed to give users the visual clarity of tools like Node-RED without the overhead of a separate execution engine, storing the logic as standard YAML that runs in the core automation engine with zero added resource use. The editor lets users drag and drop nodes to represent triggers, conditions, actions, and variable manipulation, and then compiles those flows into highly readable and native YAML that is fully compatible with Home Assistant. Users can import existing automations to visualize and edit them, and CAFE respects the same underlying data structures so the native automation editor and CAFE can interoperate on the same logic.
