![]() ![]() There is no guarantee that they will be completed in the same order. The actions will be started in parallel, but Some of the caveats of running actions in parallel: While it sounds attractive to parallelize, most of the time, just the regular There are some caveats (see below) when using parallel actions. Running actions in parallel can be helpful in many cases, but use it with The following example shows sending messages out at the same time (in parallel): The actions are started at the same time. For those cases, the parallel actionĬan be used to run the actions in the sequence in parallel, meaning all This is not always needed, for example, if the sequence of actions doesn’t rely Means the next action is started after the current action has been completed. # Example with "if" and "if" automation : - alias : " Turn lights on when the sun gets dim and if some room is occupied" trigger : - platform : numeric_state entity_id : sun.sun attribute : elevation below : 4 action : # This must always apply - service : light.turn_on data : brightness : 255 color_temp : 366 target : entity_id : - light.porch - light.garden # IF a entity is ON - choose : - conditions : - condition : state entity_id : binary_sensor.livingroom_tv state : " on" sequence : - service : light.turn_on data : brightness : 255 color_temp : 366 target : entity_id : light.livingroom # IF another entity not related to the previous, is ON - choose : - conditions : - condition : state entity_id : binary_sensor.studio_pc state : " on" sequence : - service : light.turn_on data : brightness : 255 color_temp : 366 target : entity_id : light.studio Parallelizing actionsīy default, all sequences of actions in Home Assistant run sequentially. The same concept applies to the studio room. If someone is watching the TV in the living room, there is a high chance that someone is in that room, therefore the living room lights have to turn on too. When the sun goes below the horizon, the porch and garden lights must turn on. ![]() The following example shows how a single automation can control entities that aren’t related to each other but have in common the same trigger. wait_for_trigger : - platform : event event_type : ifttt_webhook_received event_data : action : connected_to_network timeout : minutes : " " sequence : - service : script.left_home # Wait for IFTTT event or abort after specified timeout. For all the different possibilities, have a look at the service calls page. The most important one is the action to call a service. # Example script integration containing script syntax script : example_script : sequence : # This is written using the Script Syntax - alias : " Turn on ceiling light" service : light.turn_on target : entity_id : light.ceiling - alias : " Notify that ceiling light is turned on" service : notify.notify data : message : " Turned on the ceiling light!" ![]()
