configuration yaml:

template:
  - trigger:
      - platform: numeric_state
        entity_id: sensor.pool_fc
        below: 5
        for: '00:10:00'
      - platform: numeric_state
        entity_id: sensor.pool_fc
        above: 5
        for: '00:10:00'
      - platform: event
        event_type: event_template_reloaded
    binary_sensor:
      - name: Low Chlorine
        state: '{{ states("sensor.pool_fc") | float <= 4 }}'

And my automation that check for ppm <=6ppm. I found that given the inaccuracies of determining CL ppm, dosing at 6ppm works better. I also have converted to a salt pool and do not use any this anymore. I HIGHLY recommend going to salt. I have not had to add chemicals this year once I got the pool opened and stable.
