Monthly cycle progress

Configuration
1

My monthly "internet usage" cycle resets on the 21st. Does anyone have a template for tracking a monthly cycle progress as a unit float or percentage? I.e. in my case, the 21st at 12am would be 0.00, and the 20th at midnight would be 1.00.

This template would do it, bit of a kludge though

template:
- sensor:
  - name: Internet Usage Percent
    variables:
      reset_day: 21
      # Do not change
      _reset_offset: "{{ 31 - reset_day + 1 }}"
    unit_of_measurement: %
    state: >
      {% set midnight = today_at() %}
      {% set this_month = midnight.replace(day=reset_day) %}
      {% if now() > this_month %}
        {% set tspan = now() - this_month %}
        {% set next_month = (midnight + timedelta(days=_reset_offset)).replace(day=reset_day) %}
        {% set total = next_month - this_month %}
      {% else %}
        {% set last_month = (midnight.replace(day=1) - timedelta(hours=24)).replace(day=reset_day) %}
        {% set tspan = now() - last_month %}
        {% set total = this_month - last_month %}
      {% endif %}
      {{ tspan / total * 100 }}

Thanks for that!

I wasn't able to use the "variable" properties (fails with logged error "'variable' is an invalid option for 'template'"), but if I move them into the state script then it works.

It should be variables, Petro didn't eat his Wheaties today :upside_down_face:

Yep, good catch. :slightly_smiling_face:
