Services
Services are non-visual components that monitor different environment states and trigger an event when the state changes. When using multiple services, call service.event_size to determine if the specific service was updated.
| Service | Properties | Description |
|---|---|---|
http
|
url
|
Makes a GET request to a URL. Returns a single event in the queue containing the response. |
sensor
|
sensors - array of sensor names
|
Monitors one or more hardware sensors. Returns an event containing a comma-delimited list of values beginning with the sensor name (e.g. orientation,60.0,-28.0,3.0). The range of each value is dependent on the sensor.
|
timer
|
duration - time between updates, formatted as h:m:s, m:s, or s
|
Fire the update events at regular intervals. The event will first fire immediately after the service is started. Returns an event containing the datetime value when the update happened.
