Reads the current value of a Resource.
This function is available in firmware 3.1.0+.
Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
| path | String | Yes | Regular Resources: - Actual resources; must begin with a /.- These paths can be either absolute or relative. Absolute paths must begin with /app and are used without modification.- Relative paths are assumed to be with respect to /app and have /app prepended to them internally before use (e.g. The relative path argument: /myapp/mysensor/period is converted to the full path: /app/myapp/mysensor/period).Virtual Resources: Xreated from via the /virtual/config Resource. These are read using Datahub.read() and are written using the vr:// output tag in the return object. Each Virtual Resource behaves in a similar way to that of a global variable, and is accessible from all actions which belong to a particular device. These Resources are not visible between devices.- Variable names which do not contain any slashes / (i.e. no sub-directories).- When read, the terminating node /value is appended to the path. |
