hass-variables

A Home Assistant component to declare and set/update variables (state).

Since rogro82 seems to have abandoned his repository and his custom_component is really useful I just forked it and updated it so it's still works with ^2022.8.0!

Install

Manually

Copy variable folder in to your home-assistant custom_components folder

Automatically with HACS

This card is available in HACS (Home Assistant Community Store)

1. In the HACS store click on Integrations and then click on the plus in the right bottom corner. Search for hass-variables click on it and then click on INSTALL THIS REPOSITORY IN HACS.
2. Restart Home Assistant.

Then the variable custom component will be installable through HACS and you will be able to follow the future updates.

Configure

Add the component variable to your configuration and declare the variables you want.

Example configuration

variable:
  countdown_timer:
    value: 30
    attributes:
      friendly_name: 'Countdown'
      icon: mdi:alarm
  countdown_trigger:
    name: Countdown
    value: False
  light_scene:
    value: 'normal'
    attributes:
      previous: ''
    restore: true
  current_power_usage:
    force_update: true

  daily_download:
    value: 0
    restore: true
    domain: sensor
    attributes:
      state_class: measurement
      unit_of_measurement: GB
      icon: mdi:download

A variable 'should' have a value and can optionally have a name and attributes, which can be used to specify additional values but can also be used to set internal attributes like icon, friendly_name etc.

A variable can accept an optional domain which results in the entity name to start with that domain instead of variable.

In case you want your variable to restore its value and attributes after restarting you can set restore to true.

In case you want your variable to update (and add a history entry) even if the value has not changed, you can set force_update to true.

Set variables from automations

The variable component exposes 2 services:

• variable.set_variable can be used to update a variables value and/or its attributes.
• variable.set_entity can be used to update an entity value and/or its attributes.

The following parameters can be used with variable.set_variable:

• variable: string (required) The name of the variable to update
• value: any (optional) New value to set
• attributes: dictionary (optional) Attributes to set or update
• replace_attributes: boolean ( optional ) Replace or merge current attributes (default false = merge)

The following parameters can be used with variable.set_entity:

• entity: string (required) The id of the entity to update
• value: any (optional) New value to set
• attributes: dictionary (optional) Attributes to set or update
• replace_attributes: boolean ( optional ) Replace or merge current attributes (default false = merge)

Example service calls

action:
  - service: variable.set_variable
    data:
      variable: test_timer
      value: 30

action:
  - service: variable.set_variable
    data:
      variable: last_motion
      value: "livingroom"
      attributes:
          history_1: "{{states('variable.last_motion')}}"
          history_2: "{{state_attr('variable.last_motion','history_1')}}"
          history_3: "{{state_attr('variable.last_motion','history_2')}}"

action:
  - service: variable.set_entity
    data:
      entity: sensor.test_counter
      value: 30

Example timer automation

variable:
  test_timer:
    value: 0
    attributes:
      icon: mdi:alarm

script:
  schedule_test_timer:
    sequence:
      - service: variable.set_variable
        data:
          variable: test_timer
          value: 30
      - service: automation.turn_on
        data:
          entity_id: automation.test_timer_countdown

automation:
  - alias: test_timer_countdown
    initial_state: 'off'
    trigger:
      - platform: time_pattern
        seconds: '/1'
    action:
      - service: variable.set_variable
        data:
          variable: test_timer
          value: >
            {{ [((states('variable.test_timer') | int(default=0)) - 1), 0] | max }}

  - alias: test_timer_trigger
    trigger:
      platform: state
      entity_id: variable.test_timer
      to: '0'
    action:
      - service: automation.turn_off
        data:
          entity_id: automation.test_timer_countdown

Play and Save TTS Messages + Message History - Made by https://github.com/jazzyisj

This is more or less an answering machine (remember those?) for your TTS messages. When you play a TTS message that you want saved under certain conditions (ie. nobody is home), you will call the script Play or Save TTS Message script.play_or_save_message instead of calling your tts service (or Alexa notify) directly. The script will decide whether to play the message immediately, or save it based on the conditions you specify. If a saved tts message is repeated another message is not saved, only the timestamp is updated to the most recent instance.

Messages are played back using the Play Saved TTS Messages script script.play_saved_tts_messages. Set an appropriate trigger (for example when you arrive home) in the automation Play Saved Messages automation.play_saved_messages automation to call this script automatically.

Saved messages will survive restarts.

BONUS - OPTIONAL TTS MESSAGE HISTORY

You can find the full documentation on how to do this and andjust this to your needs in here.

More examples can be found in the examples folder.
