:battery: [Blueprint] UPS Monitor via NUT – Battery, Status & Self-Test Notifications

This blueprint monitors a UPS device integrated via the NUT integration in Home Assistant.

It automatically sends notifications to your phone when:

  • :arrows_counterclockwise: UPS status changes (e.g., Online → On Battery)
  • :battery: UPS battery charge drops by a defined interval (default: every 10%)
  • :test_tube: UPS self-test result is not “Done and passed”

The automation includes battery voltage and charge % in the message when relevant.

:white_check_mark: Features

  • Uses status_data (e.g., OL, OB) for logic and status (e.g., Online) for human-readable messages
