cafe-hass

cafe-hass is a drag-and-drop editor for Home Assistant automations. Instead of hand-writing YAML, you build your logic as a flowchart and it transpiles down to native Home Assistant automations. If you have ever stared at indentation errors trying to get a motion sensor to do the right thing, this is the visual layer that fixes that. MIT, free, installs through HACS.

Because it outputs standard Home Assistant YAML, there is no separate engine running, the automations are native once generated, which means you are not adding another always-on service to babysit the way you would with Node-RED. It lives entirely inside your self-hosted Home Assistant. Setup is trivial if you already run HACS.

This is for Home Assistant users who want visual automation building without standing up Node-RED alongside it. Solo home setups, which is basically everyone here, it is free, full stop. The flip side: it only matters if you run Home Assistant, and because it compiles to YAML, deeply custom logic can still bump into Home Assistant's native automation limits.

The catch is the niche. cafe-hass solves a real annoyance, and it solves it for exactly one audience: people already running Home Assistant. Outside that world it has no reason to exist. Inside it, it is one of the nicer ways to stop fighting YAML.
