- Microcontroller hobbyists building sensor-driven workflows
- Worth noticing
- The component catalog spans sensors, displays, networking, logic, and filesystems, with ESP32 named as the out-of-the-box board.
Field notes
The workflow model combines trigger branches, action nodes, bindings, and variables; the page says triggers can run side by side. Its debugging description includes running one action at a time or waiting for a trigger, inspecting outputs, editing values, and continuing. The site also says components can be installed from a registry or published as npm packages, and that workflows can be moved as .hio files.
