#
# This is an integration that makes it possible to send notifications via Home Assistant (https://www.home-assistant.io/integrations/notify/)
# You need to generate a long-lived access token in Home Sssistant to be used here (https://developers.home-assistant.io/docs/auth_api/#long-lived-access-token)
# Leave (or place) this file in the "notify_templates" subdirectory within the same directory as the main dockcheck.sh script.
# If you instead wish make your own modifications, make a copy in the same directory as the main dockcheck.sh script.
# Do not modify this file directly within the "notify_templates" subdirectory. Set HA_ENTITY, HA_URL and HA_TOKEN in your dockcheck.config file.
