Hello, i have downloaded this Package for receive notification of low battery in my devices:

Battery Alert Package by NotoriousBDG

## Install Instructions
################################################################
##
## 1. Enable MQTT using your preferred MQTT broker
## https://home-assistant.io/components/mqtt/
##
## 2. Enable MQTT Discovery by adding `discovery: true` and
## `discovery_prefix: homeassistant` under the `mqtt:` section
## of your configuration.yaml
##
## mqtt:
## discovery: true
## discovery_prefix: homeassistant
##
## 3. Save this file as CONFIGDIR/packages/battery_alert.yaml
##
## 4. Add `packages: !include_dir_named packages` under the
## `homeassistant:` section of your configuration.yaml
##
## homeassistant:
## packages: !include_dir_named packages
##
## 5. Restart Home Assistant
##
## 6. Adjust Min Alert Threshold slider to the minimum battery
## level to alert on. Note: the input slider requires the
## recorder component to keep it's state through restarts.
## If recorder is not enabled, the threshold can be set by
## un-remarking `initial` and setting the preferred default.
##
## 7. Adjust Max Alert Threshold slider to the maximum battery
## level to alert on. Note: the input slider requires the
## recorder component to keep it's state through restarts.
## If recorder is not enabled, the threshold can be set by
## un-remarking `initial` and setting the preferred default.
##
## 8. Setup notifications by entering the notifier name in the `Notifier Name` input text box.
## E.g. `notify.slack`. If no value is entered, it defaults to `notify.notify`.
##
## 9. Set the notifier format by selecting either `Default` or `Slack. Note: most notifiers
## are compatible with the `Default` format.
##
## 10. To disable alerts for a specific entity, use customize to
## set `battery_alert_disabled` to `true`
##
## homeassistant:
## customize:
## sensor.sensor_name_to_ignore_battery:
## battery_alert_disabled: true
##
## 11. To disable creating a sensor from battery attributes for a specific entity, use customize to
## set `battery_sensor_creation_disabled` to `true`
##
## homeassistant:
## customize:
## sensor.sensor_with_battery_attibute:
## battery_sensor_creation_disabled: true
##
## 12. If a battery attribute requires a template to convert it into a usable percent, use customize
## to add `battery_template` with the necessary template. The template result must be a number
## that represents a percentage.
##
## This example will create a battery sensor with the value of battery_level * 2
##
## homeassistant:
## customize:
## sensor.sensor_with_battery_attibute_template:
## battery_template: "{{ value_json.value | int * 2 }}"
##
## 13. If a battery attribute requires a template to convert it into a string, use customize to add
## `battery_template_string` with the necessary template. The template result must be a string.
## For example, "Low" will trigger low battery notification).
##
## This example will create a battery sensor that contains "Low" if battery_level
## is less than 2
##
## homeassistant:
## customize:
## sensor.sensor_with_battery_attibute_template:
## battery_template_string: >-
## {%- if value_json.value < 2 -%}
## Low
## {%- else -%}
## Full
## {%- endif -%}
