Limit notifications by time?

Configuration
1

I’m using on a binary_sensor for motion, and it can can trigger many times per second. Is there a way for the notification action to be rate limited so that notifications are only sent so many times per time period?

Here’s my workaround:

automation.yaml:

- alias: Notify on motion during workday
  trigger:
    platform: state
    entity_id: binary_sensor.garage_motion, binary_sensor.office_motion
    to: 'on'
  condition:
    condition: time
    after: '8:00:00'
    before: '17:00:00'
    weekday:
      - mon
      - tue
      - wed
      - thu
      - fri
  action:
    service: notify.motion_detected

notify.yaml:

- platform: command_line
  name: motion_detected
  command: "/etc/hass/scripts/notify_motion"

/etc/hass/scripts/notify_motion:

#!/bin/sh
delayseconds=600
nextnotify=$(cat /etc/hass/scripts/notify_motion.dat 2>/dev/null)
timenow=$(date +"%s")
if [ "${nextnotify}" = "" ]; then
  echo ${timenow} > /etc/hass/scripts/notify_motion.dat
  exit
fi
if [ "${timenow}" -gt "${nextnotify}" ]; then
  nextnotify=$((timenow+delayseconds))
  echo ${nextnotify} > /etc/hass/scripts/notify_motion.dat
  subject="Motion detected"
  message=${subject}
  echo "${message}" | mail -s "${subject}" [email protected]
  echo "Notifying..."
else
  echo "Next notification in $((nextnotify-timenow)) seconds..."
fi
