The template
platform creates locks that combines components.
For example, if you have a garage door with a toggle switch that operates the motor and a sensor that allows you know whether the door is open or closed, you can combine these into a lock that knows whether the garage door is open or closed.
This can simplify the GUI and make it easier to write automations. You can mark the components you have combined as hidden
so they don't appear themselves.
In optimistic mode, the lock will immediately change state after every command. Otherwise, the lock will wait for state confirmation from the template. Try to enable it, if experiencing incorrect lock operation.
{% linkable_title Configuration %}
To enable Template Locks in your installation, add the following to your configuration.yaml
file:
{% raw %}
# Example configuration.yaml entry
lock:
- platform: template
name: Garage door
value_template: "{{ is_state('sensor.door', 'on') }}"
lock:
service: switch.turn_on
data:
entity_id: switch.door
unlock:
service: switch.turn_off
data:
entity_id: switch.door
{% endraw %}
{% configuration %} name: description: Name to use in the frontend. required: false type: string default: Template Lock value_template: description: Defines a template to set the state of the lock. required: true type: template lock: description: Defines an action to run when the lock is locked. required: true type: action unlock: description: Defines an action to run when the lock is unlocked. required: true type: action optimistic: description: Flag that defines if lock works in optimistic mode. required: false type: boolean default: false {% endconfiguration %}
{% linkable_title Considerations %}
If you are using the state of a platform that takes extra time to load, the Template Lock may get an unknown
state during startup. This results in error messages in your log file until that platform has completed loading. If you use is_state()
function in your template, you can avoid this situation. For example, you would replace {% raw %}{{ states.switch.source.state == 'on' }}
{% endraw %} with this equivalent that returns true
/false
and never gives an unknown result: {% raw %}{{ is_state('switch.source', 'on') }}
{% endraw %}
{% linkable_title Examples %}
In this section, you find some real-life examples of how to use this lock.
{% linkable_title Lock from Switch %}
This example shows a lock that copies data from a switch.
{% raw %}
lock:
- platform: template
name: Garage Door
value_template: "{{ is_state('switch.source', 'on') }}"
lock:
service: switch.turn_on
data:
entity_id: switch.source
unlock:
service: switch.turn_off
data:
entity_id: switch.source
{% endraw %}
{% linkable_title Optimistic Mode %}
This example shows a lock in optimistic mode. This lock will immediately change state after command and will not wait for state update from the sensor.
{% raw %}
lock:
- platform: template
name: Garage Door
value_template: "{{ is_state('sensor.skylight.state', 'on') }}"
optimistic: true
lock:
service: switch.turn_on
data:
entity_id: switch.source
unlock:
service: switch.turn_off
data:
entity_id: switch.source
{% endraw %}
{% linkable_title Sensor and Two Switches %}
This example shows a lock that takes its state from a sensor, and uses two momentary switches to control a device.
{% raw %}
lock:
- platform: template
name: Garage Door
value_template: "{{ is_state('sensor.skylight.state', 'on') }}"
lock:
service: switch.turn_on
data:
entity_id: switch.skylight_open
unlock:
service: switch.turn_on
data:
entity_id: switch.skylight_close
{% endraw %}
