A python script for Homeassistant that counts down the days to birthdays, anniversaries etc
This script creates a sensor that a counts down to the next occurrance of a date, like a birthday or anniversary and gives the number of years as an attribute
Requires python_script:
to be enabled in you configuration
Copy the Python script in to your /config/python_scripts
directory or install via HACS.
key | required | type | description |
---|---|---|---|
name: |
True | string | Name of the date (eg. John) |
type: |
True | string | Type of date (eg. Birthday) |
date: |
True | string | Date, in format DD/MM/YYYY |
The date can be in the future if you want to countdown to the date itself, and then the anniversaries thereafter.
Each sensor requires:
name: NAME_OF_DATE
type: TYPE_OF_DATE
date: DD/MM/YYYY_OF DATE
examples:
name: John
type: birthday
date: 17/08/1971
or
name: Our wedding
type: anniversary
date: 14/02/1994
Each sensor is given the following automatically:
entity_id: sensor.<type>_<name>
friendly_name: <name> <type>
state: <Days to the date from today>
nextoccur: <Date of next occurance>
years: <Number of years it will be>
So, the two sensors we created above would come out as:
sensor.birthday_john
friendly_name: John’s birthday
state: However many days it is until 17th August
nextoccur: 17/08/YYYY (either this year or next year as appropriate)
years: However old John will be on his next birthday
sensor.anniversary_our_wedding
friendly_name: Our wedding anniversary
state: However many days to 14th February
nextoccur: 14/02/YYYY (either this year or next year as appropriate)
years: How many years you will have been married on that day
Note that if the type is 'birthday' the sensor will automatically add an apostrophe.
An example automation to create and refresh the above two sensors daily would be:
automation:
- alias: Reminder - Refresh date countdown sensors
trigger:
- platform: time
at: '00:00:01'
- platform: homeassistant
event: start
action:
- service: python_script.date_countdown
data:
name: John
type: birthday
date: 17/08/1971
- service: python_script.date_countdown
data:
name: Our wedding
type: anniversary
date: 14/02/1994
An example automation to remind you of an event 7 days before it occurs would be:
automation:
- alias: Reminder - John's birthday is coming up
trigger:
- platform: state
entity_id: sensor.birthday_john
to: '7'
action:
- wait_template: "{{ states('sensor.time') == '10:00' }}"
- service: notify.notify
data:
message: "John's birthday is only a week away!"
Utilising the attributes provided and the custom lovelace card for adding secondary info to an entity row.
type: entities
show_header_toggle: false
title: Our Events
entities:
- entity: sensor.anniversary_our_wedding
secondary_info: '[[ {entity}.attributes.nextoccur ]] ( [[ {entity}.attributes.years ]] Years )'
type: 'custom:secondaryinfo-entity-row'
Will provide the following lovelace representation:
Thanks to @myle for the idea for the extra attributes and the lovelace presentation.
Thanks to AJax2012 for the PR that caters for future dates, and makes the apostrophes in the friendly names only append to birthday sensors.
