property.change Event

Thing key

String

This trigger can be limited to a thing specified by key. Leave blank to not limit this trigger to a specific thing.

Thing tags

String

This trigger can be limited to things specified by tags. Leave blank to not limit this trigger to things specified by tag.

Property key

String

This trigger can be limited to a specified property by key. Leave blank to not limit this trigger to a specific property.

Operator

String

Yes

The condition or comparison that initiates this trigger. Triggers can be set to always execute when a property is published, or only when the property published is different than the current property value (neprevious), or it can be set to execute when the value is less than (<), less than or equal to (<=), equal to (==), not equal to (!=), greater than or equal to (>=), greater than (>), between two values including the lower bound and not the upper bound (operand 1 <= and < operand2), or between two other values including both the lower and upper bound (operand 1 <= and <= operand2).

Operand

String

The threshold that the published property value is compared to. In the between operator case, the two operands should be separated by a comma (,).

On edge

Boolean

Limits the number of times a trigger executes to instances when the property value crosses the threshold. Using On Edge will limit the execution of this trigger to the first publish that satisfies the condition, but not for subsequent publishes that also satisfy the condition. Once a property value is published that is outside of the condition, the On Edge restriction is reset and the next property publish that satisfies the condition would cause the trigger to execute.

Time in condition (seconds)

Integer

The number of seconds the property must maintain the current value before the trigger is executed.

$(event.location.heading)

Float

The heading of the thing's current location.

$(event.location.lat)

Float

The latitude of the thing's current location.

$(event.location.lng)

Float

The longitude of the thing's current location.

$(event.location.speed)

Integer

The speed of the thing at the thing's current location.

$(event.prev.ts)

String

The timestamp associated with the thing's previously published location.

$(event.prev.value)

Integer

The value of the previous property publish.

$(event.prop.corrId)

String

The correlation ID of the property record.

$(event.prop.key)

String

The key of the property that initiated this trigger.

$(event.prop.name)

String

The name of the property that initiated this trigger.

$(event.prop.ts)

String

The timestamp of the property publish that initiated this trigger.

$(event.prop.unit)
