Heating scenario for shift work

Configuration
1

My wife is a shift worker with alternating rotations. There is no digital calendar (Germany - you know…) with a rotation schedule in it. There is only a piece of paper available…

So we have no data for the automation.

Idea: I would like to give her a small button that she can press before she goes to bed to activate the heating in the bathroom in time the next morning.

What I did so far…

alias: New Automation
description: ""
trigger:
  - platform: event
    event_type: hue_event
    event_data:
      unique_id: id....
condition:
  - condition: or
    conditions:
      - condition: template
        value_template: "{{ trigger.event.data.type == 'short_release' }}"
      - condition: template
        value_template: "{{ trigger.event.data.type == 'initial_press' }}"
action:
  - service: climate.set_temperature
    data:
      temperature: 22
      hvac_mode: heat
    target:
      device_id: id....
  - delay:
      hours: 0
      minutes: 0
      seconds: 15
      milliseconds: 0
  - service: climate.set_hvac_mode
    data:
      hvac_mode: auto
    target:
      device_id: id.....
mode: single

Now I still need to calculate a delay before the action runs. I have already implemented this in Python as follows

import datetime

current_date = datetime.datetime.today()
today_schedule = current_date.replace(hour=4, minute=30, second=0, microsecond=0)

if (current_date < today_schedule):
  #today
  delta = today_schedule - current_date
  delta_m = int(delta.total_seconds()/60)
  print(delta_m)
else:
  #tomorrow
  next_day_schedule = (datetime.datetime.today() + datetime.timedelta(days=1)).replace(hour=4, minute=30, second=0, microsecond=0)
  delta = next_day_schedule - current_date
  delta_m = int(delta.total_seconds()/60)
  print (delta_m)

How do you like this approach?
How can I build this calculation into a delay?

Thank you for your help in advanced…

Cheers,
Marcel

Update:

This is my Solution in total:

Why not, install HA app on her phone, and use location (Distance) to check if she or you are home.

Thats what I do :slight_smile:
