I’ve even created a much sofisticated design.

ngbs_turned_on1:
        friendly_name: Time passed
        entity_id: sensor.time
        value_template: >-
                  {% set time = ((as_timestamp(now()) - as_timestamp(states.sensor.pump.last_changed))) | round(0) %}
                  {% set minutes = ((time % 3600) / 60) | int %}
                  {% set hours = ((time % 86400) / 3600) | int %}
                  {% set days = (time / 86400) | int %}
                  {%- if time < 60 -%}
                    Less than a minute
                  {%- else -%}
                    {%- if days > 0 -%}
                      {%- if days == 1 -%}
                        1 day
                      {%- else -%}
                        {{ days }} days
                      {%- endif -%}
                    {%- endif -%}
                    {%- if hours > 0 -%}
                      {%- if days > 0 -%}
                        {{ ', ' }}
                      {%- endif -%}
                      {%- if hours == 1 -%}
                        1 hour
                      {%- else -%}
                        {{ hours }} hours
                      {%- endif -%}
                    {%- endif -%}
                    {%- if minutes > 0 -%}
                      {%- if days > 0 or hours > 0 -%}
                        {{ ', ' }}
                      {%- endif -%}
                      {%- if minutes == 1 -%}
                        1 minute
                      {%- else -%}
                        {{ minutes }} minutes
                      {%- endif -%}
                    {%- endif -%}
                  {%- endif -%}

Based on this solution.
