First thing - exclude recording of the devices. My method was to use a glob so I name devices/entity IDs specifically and they don't get recorded (in my case I used f_ as in "filtered" so devices become like "F Source Presence"), but you can add specific entities or use your own glob. In configuration.yaml I have this:

recorder:
  exclude:
    entities:
      - sensor.excluded_entity_1
    # AND/OR this (then of course rename entities as needed)
    entity_globs:
      # exclude all sensor entities that start with f_
      - sensor.f_*

Then I created templates for my presence sensors, that just copy the state so I get history (yaml here, but can do through UI now too in the Helpers section, the import part is the template in the state key below):

template:
  - binary_sensor:
      - name: Real presence
        unique_id: my_presence
        state: >-
          {{ states('binary_sensor.f_source_presence}}
        availability: >-
          {{
            not (
              states('binary_sensor.f_source_presence') == 'unknown' or
              states('binary_sensor.f_source_presence') == 'unavailable'
            )
          }}
        device_class: presence

You could also use a statistics sensor to get a moving average for numeric values and get history from them too (and reduce the noise by reducing the precision and having a larger time window). This is also available through the UI - Helpers.
