Packages as Templates
*********************
Since packages are incorporated using the ``!include`` system,
variables can be provided to them. This means that packages can be
used as `templates`, allowing complex or repetitive configurations to
be stored in a package file and then incorporated into the
configuration more than once.
As an example, if the configuration needed to support three garage
doors using the ``gpio`` switch platform and the ``time_based`` cover
platform, it could be constructed like this:
.. code-block:: yaml
# In config.yaml
packages:
left_garage_door: !include
file: garage-door.yaml
vars:
door_name: Left
door_location: left
open_switch_gpio: 25
close_switch_gpio: 26
middle_garage_door: !include
file: garage-door.yaml
vars:
door_name: Middle
door_location: middle
open_switch_gpio: 27
close_switch_gpio: 29
right_garage_door: !include
file: garage-door.yaml
vars:
door_name: Right
door_location: right
open_switch_gpio: 15
close_switch_gpio: 18
.. code-block:: yaml
# In garage-door.yaml
switch:
- id: open_${door_location}_door_switch
name: ${door_name} Garage Door Open Switch
platform: gpio
pin: ${open_switch_gpio}
- id: close_${door_location}_door_switch
name: ${door_name} Garage Door Close Switch
platform: gpio
pin: ${close_switch_gpio}
cover:
- platform: time_based
name: ${door_name} Garage Door
open_action:
- switch.turn_on: open_${door_location}_door_switch
open_duration: 2.1min
close_action:
- switch.turn_on: close_${door_location}_door_switch
close_duration: 2min
stop_action:
- switch.turn_off: open_${door_location}_door_switch
- switch.turn_off: close_${door_location}_door_switch
