Pulse Catcher

The Pulse Meter can be used as a very fast pulse catcher. This can be useful if you would like to detect an incoming pulse on a GPIO pin shorter than the typical 16ms loop interval.

sensor:
  - platform: pulse_meter
    pin: GPIOXX
#    internal_filter: 1ms # If a pulse shorter than this time is detected, it is discarded. Defaults to 13us.
    id: trigger
    filters:
      - lambda: return {}; # Don't return any pulses/s to not spam the logs
    total:
      id: pulses
      on_value:
        then:
          # Do something cool when a pulse is detected, like flashing a led e.g.
          - output.turn_on: led
          - delay: 500ms
          - output.turn_off: led
