Data bindings and actions

Bindings determine what a component displays. Actions determine what happens when a viewer uses it.

Workflow

1. Static data is stored with the project. Request reads once; Polling refreshes periodically; WebSocket receives a stream.
2. Configure URL, method, response path and refresh settings only for the chosen source type.
3. Map fields such as label/value, x/y and series. Test a small known sample first.
4. For actions, choose the action type and its target. A temperature slider can evaluate a status-alarm rule on a device.
5. Do not put private credentials in a publicly shared project.
