my shift

base on your work patten will work out if you on/off even if you do days then nite like i do 2 days swing day then 2 nites then 4 days off :)

Big thanks to mf-socials for his countdown script

that pointed me down down the track well where to start so thanks mf-socials again

Had the logic just did not know were to start

first wrote it in vb that was easy

python still getting head around it

took me longer to write this readme than to write the code.

How it works

This script creates a sensor that work out weather you are on/off for today with a heap of attribute

Requires python_script: to be enabled in you configuration

Installation

Copy the Python script in to your /config/python_scripts

Script arguments

key	required	type	description
name:	True	string	Name of the date (eg. StePhan)
shiftpatten:	True	string	Type of Shift
firstdayshift:	True	string	Date, in format DD/MM/YYYY day 1 of shift patten
patten:	True	string	What the Patten DDNN = (doing 2 days then 2 nigths)
'holiday_start:'	True	string	Date, in format DD/MM/YYYY of holiday start
'holiday_end:'	True	string	Date, in format DD/MM/YYYY of holiday end

patten: is what shift patten are you doing eg DDNN = work 2 days then 2 nites

DDDDD = work 5 days in a row

firstdayshift: only has tobe full out once as it just uses maths to work out weather you on/off

shiftpatten	patten
'4x4x12'	4 days ON x 4 days off x 12 hour days and it a 8 day cycle
'4x2x12'	4 days ON x 2 days off x 12 hour days and it a 6 day cycle
'5x2x8'	5 days ON x 2 days off x 8 hour days and it a 7 day cycle
'6x1x8'	6 days ON x 1 day off x 8 hour days and it a 7 day cycle

NOTE:

holiday_start: and holiday_end: will only kick in after next restart

must be small x

I have tested the above shiftpatten if someone has a differance patten it should work

if you are a monday-friday worker try this workday Binary Sensor as this look at the public hoildays in your country

Usage

Each sensor requires:

name: NAME_OF_SHIFT_PATTEN
shiftpatten: SHIFT_PATTEN 4x4x12
patten: DDNN
firstdayshift: DD/MM/YYYY_date of first day of the patten must be sometime in the pass

examples:

name: StePhan
shiftpatten: 4x4x12
patten: DDNN
firstdayshift: 20/10/2019
holiday_start: 26/05/2020
holiday_end: 12/07/2020

So, the sensor we created above would come out as:

icon: 'mdi:calendar-star'
friendly_name: StePhan's Roster
shift patten: 4x4x12
patten: DDNN
day_of_this_shift_patten: '2'
this_day: Day
next_start_date: 5/11/2019
First_Day_Shift_Was: 20/10/2019

Example configuration.yaml entry

An example automation to create and refresh the above two sensors daily would be:

automation:
  - alias: set the shift patten on/off
    trigger:
      - platform: time
        at: '00:00:01'
      - platform: homeassistant
        event: start
    action:
      - service: python_script.my_shift
        data:
          name: StePhan
          shiftpatten: 4x4x12
          patten: DDNN
          firstdayshift: 20/10/2019

Showing it in lovelace

An example for lovelace (at this point of time you have to the secondaryinfo-entity-row )

  - entity: sensor.stephan_4x4x12
    secondary_info: ' Next start: [[ {entity}.attributes.nextstartdate ]]''
    type: 'custom:secondaryinfo-entity-row'

next start date will show in secondary_info line

how I use in my house

As the alarm wakes me 2 day out of 8 day cycle

#=======================================================================
- id: 'Wake me up roster only morning'
  alias: Wake me up roster morning
  trigger:
  - at: '4:00:00'
    platform: time
  condition:
    condition: and
    conditions:
    - condition: state
      entity_id: sensor.stephan_4x4x12
      state: 'on'
    - condition: template
    # read the attributes of my sensor am I on DAYS/NIGHT of off
      value_template: >-
        {{states.sensor.stephan_4x4x12.attributes["this_day"] == 'Day'}}
  action:
