Attributes

For the Home Assistant Template editor or Automations/Scripts.

Basics attributes

{{states("input_number.cctime")}}
or
{{ (states("input_number.cctime")) }} all returns 4.0

same as above but without error handeling:
{{ states.input_number.cctime.state}}

Basic Manipulation

{{ (states("input_number.cctime") | int *60 ) }} returns 240

{{ relative_time(states.binary_sensor.mija_door.last_changed) }} returns 1 hour

Template editor

Replace

{% set my_test_json = {
  "gps": "7.8199286,-122.4782551"
} %}
 {{ my_test_json.temperature }} 
{{ my_test_json.gps | replace(",",":")  }} 

returns 7.8199286:-122.4782551

Split

{% set my_test_json = {
  "gps": "7.8199286,-122.4782551"
} %}
 {{ my_test_json.temperature }} 
{{ my_test_json.gps.split(',')[0] }} 

returns 7.8199286

(',')[1] }} would return -122.4782551

cut out the name and capitalize the first letter

{{ 'binary_sensor.waschmaschine_running' | regex_replace('.*\.', '') | regex_replace('_.*', '') | title }}

cut out the new line

"{{something['somethingRece ived'].replace('\n', ''}}"

returns Waschmaschine

get all attrbutes of a given entity_id

% set entity_id = "automation.tasker_hook" %}

{{ entity_id }}

{{ states[entity_id.split('.')[0]] }}
{{ states[entity_id.split('.')[0]] | list }}
{{ states[entity_id.split('.')[0]][entity_id.split('.')[1]] }}

{{ (states[entity_id.split('.')[0]][entity_id.split('.')[1]]).attributes.friendly_name }}
{{ (states[entity_id.split('.')[0]][entity_id.split('.')[1]]).attributes["friendly_name"] }}

Of an domain:

{% for state in states.zone -%}
  {{ state.entity_id }}:

 {{state.attributes}}
{% endfor %}

templating out of these propertys

{% for zone in states.zone -%}
- name: {{ state_attr(zone.entity_id, 'friendly_name') }}
  latitude: {{ state_attr(zone.entity_id, 'latitude') }}
  longitude: {{ state_attr(zone.entity_id, 'longitude') }}
  radius: {{ state_attr(zone.entity_id, 'radius') }}
{{ '\n' -}} 
{%- endfor %}

#by ludeeus:
{%- for state in states.zone -%}
- name: {{ state_attr(state.entity_id, 'friendly_name') }}
 {%- for attr in ["latitude", "longitude", "radius", "icon"] %}
  {{attr}}: {{ state_attr(state.entity_id, attr) }}
 {%- endfor %}

  State changed by: {{ state_attr(user.entity_id, 'friendly_name') }}
  {%- endif -%}
{%- endfor -%}

returns State changed by: XY

loop through a list, and break out of the loop

messages

random

      - service: notify.xyz
        data_template:
          message: >-
                 {{ [
                 " message 0",
                 " message 1",
                 " message 2",
                 " message 3",
                 " message 4",
                 " message 5",
                 " message 6",
                 " message 7",
                 " message 8",
                 " message 9",
                 " message 10"
                 ] | random }}

output:

returns `message 10`, then `message 4`, then `message 3`, then `message 10`, then...

could be used with {{now().strftime('%d')}} for things like open contests.

Keep the style

  platform: file
  filename: /config/notify.log
  timestamp: true
automation:
  trigger:
  action:
    - service: notify.logfile
      data_template:

string to stamp

string from sensor.ups_transfer_to_battery.state: 2019-06-12 09:44:56 +0700
Convert it to an timestamp and get the relative time: {{ relative_time(strptime(states.sensor.ups_transfer_to_battery.state, '%Y-%m-%d %H:%M:%S %z')) }}

timezones

| timestamp_custom('%Y-%m-%dT%H:%M:%S', False) }}Z timestamp_custom also lets you flag if the time is local time or not

you can add {{ | timestamp_local }} for Local or {{ | timestamp_utc }} {{ | timestamp_custom('%Y' True) }}

Create a timestamp with an automation

automation:
  - alias: timestamp
    trigger:
    action:
      - service: notify.timestamp
        data_template:
          message: "{{ { 'timestamp': now()|string } |tojson }}"
 
sensor:
  - platform: file
    name: vit_d3_timestamp
    file_path: /config/imestamp.txt
    value_template: '{{value_json.timestamp}}'
  - platform: template
    sensors:
      timestamp_processed:
        friendly_name: "timestamp"
        unit_of_measurement: 'days'
        value_template: "{{ (( as_timestamp(now()) - as_timestamp(strptime(states('sensor.timestamp'), '%d.%m.%Y')) ) / 86400 ) | round(2) }}"

When you got already a timestamp you can use it like state_attr('input_datetime.date_time','timestamp')) `
