AutoRefreshed[expr]

represents an expression to be reevaluated every hour and made available in the cloud.

AutoRefreshed[expr,dt]

reevaluates at time interval dt.

AutoRefreshed[expr,timespec]

reevaluates on the schedule specified by timespec.

AutoRefreshed[expr,timespec,fmt]

specifies that the result from evaluating expr should be given in format fmt.

AutoRefreshed[expr,timespec,{fmt,rform}]

specifies that the result should be given as a response of the form rform.

AutoRefreshed[expr]

represents an expression to be reevaluated every hour and made available in the cloud.

AutoRefreshed[expr,dt]

reevaluates at time interval dt.

AutoRefreshed[expr,timespec]

reevaluates on the schedule specified by timespec.

AutoRefreshed[expr,timespec,fmt]

specifies that the result from evaluating expr should be given in format fmt.

AutoRefreshed[expr,timespec,{fmt,rform}]

specifies that the result should be given as a response of the form rform.

Details

AutoRefreshed is typically used with CloudDeploy to create a cloud object whose content is automatically updated on a schedule.
timespec follows the specification for scheduled tasks.
Possible result formats fmt in AutoRefreshed[expr,fmt] are:
"fmt" any format supported by ExportForm

fun an arbitrary function to be applied to expr
AutoRefreshed[expr,"fmt"] is equivalent to AutoRefreshed[ExportForm[expr,"fmt"]].
AutoRefreshed objects may be removed using DeleteObject or TaskRemove.

Basic Examples (5)

Deploy a time stamp that updates once per hour:

Wolfram Language code: o = CloudDeploy[AutoRefreshed[Now]]

Delete the object:

Wolfram Language code: DeleteObject[o]

Sample the air pressure once per hour:

Wolfram Language code: o = CloudDeploy[AutoRefreshed[AirPressureData[], "Hourly"]]

Delete the object:

Wolfram Language code: DeleteObject[o]

Sample the air pressure every three hours:

Wolfram Language code: o = CloudDeploy[AutoRefreshed[AirPressureData[], Quantity[3, "Hours"]]]

Delete the object:

Wolfram Language code: DeleteObject[o]

Deploy a moon phase icon that updates daily:

Wolfram Language code: o = CloudDeploy[AutoRefreshed[MoonPhase["Icon"], "Daily", "PNG"]]

Delete the object:

Wolfram Language code: DeleteObject[o]

Sample the air pressure hourly as text, while showing the EvaluationData as JSON:

Wolfram Language code: o = CloudDeploy[AutoRefreshed[AirPressureData[], "Hourly", {"Text", "JSON"}]]

Delete the object:

Wolfram Language code: DeleteObject[o]

Possible Issues (1)

When AutoRefreshed is evaluated in the cloud, it has restrictions on memory usage and evaluation time. The limitations are determined by your cloud plan, and the amounts can be found in CloudAccountData as "ScheduledTaskMemoryLimit" and "ScheduledTaskEvaluationTimeLimit":

Wolfram Language code: CloudAccountData /@ {"ScheduledTaskMemoryLimit", "ScheduledTaskEvaluationTimeLimit"}
