Tracking Daily Online Hours via Ping

[baspax1]

Good evening, what I want to achieve is to record the total hours a computer is online via Ping. I see it's not recording accurately, I want it to separate the data by day and produce a total of hours per day, in hours and minutes if possible.

Sensor

  - platform: history_stats
    name: Chris PC Daily Uptime
    entity_id: binary_sensor.chris_pc
    state: 'on'
    type: time
    start: '{{ now().replace(hour=0, minute=0, second=0) }}'
    end: '{{ now() }}'
