Entities & services

Integration creates switch timer entity for every switch entity in the home assistant instance. Switch timer entities are assigned to switch_timer domain, the entity name remains the same as original switch entity. As for example, switch.kitchen_light => switch_timer.kitchen_light. The integration scans for new switch entities every 10 seconds, if a new switch entity is found, a switch timer entity is created for it automatically. A switch timer entity state can be either set or idle. An entity changes its state from idle to set when a timer is scheduled. Note that all scheduled timers are dropped upon a system restart, will change this in a future release. The integration provides two services for both scheduling and canceling timers. A set switch timer entity has the following attributes,

• finishing_at Shows the UTC timestamp when timer is scheduled to run
• duration Duration of the timer in HH:MM:SS format
• action State scheduled for the corresponding switch entity to be set to. Possible values, 'turn_on', 'turn_off, 'toggle'

  

switch_timer.set_timer

Service used for scheduling a timer. Maximum timer duration supported is 23:59:59. Required parameters are,

• entity_id switch timer entity to set the timer for
• action state action to be set on the corresponding switch entity
• duration duration for the timer in HH:MM:SS format

action: switch_timer.set_timer
data:
  entity_id: switch_timer.kitchen_light
  action: "turn_off"
  duration: "00:10:00"

Example service call on switch_timer.kitchen_light entity to turn the device off after 10 minutes.

switch_timer.cancel_timer

Service used for canceling a scheduled timer. The entity_id for the timer to be canceled is required.

action: switch_timer.cancel_timer
data:
  entity_id: switch_timer.kitchen_light

Example service call to cancel the timer scheduled on switch_timer.kitchen_light entity.

Both services have a GUI support implemented in developer tools section.

Frontend usage

Set timer popup card

In order to easily set timers for devices straight from the dashboard, I've created set timer popup card, which can be displayed in a browser mod popup as a hold action on a card, for example.
