Triggered

This property is the same as the run property except rather than passing an event object to the automation block the triggered item is passed. This enables optimizations for simple cases and supports ruby’s pretzel colon &: operator.

Examples

rule 'Triggered has access directly to item triggered' do
  changed TestSwitch
  triggered { |item| logger.info("#{item.id} triggered") }
end

Triggered items are highly useful when working with groups

#Switches is a group of Switch items

rule 'Triggered item is item changed when a group item is changed.' do
  changed Switches.members
  triggered { |item| logger.info("Switch #{item.id} changed to #{item}")}
end


rule 'Turn off any switch that changes' do
  changed Switches.members
  triggered(&:off)
end

Like other execution blocks, multiple triggered blocks are supported in a single rule

rule 'Turn a switch off and log it, 5 seconds after turning it on' do
  changed Switches.members, to: ON
  delay 5.seconds
  triggered(&:off)
  triggered {|item| logger.info("#{item.label} turned off") }
end
