# Power Spike Tracker Blueprint
# =============================================================================
# This blueprint monitors power sensors for abnormal consumption spikes that
# might indicate device malfunction or safety concerns.
#
# Features:
# - Monitors multiple power sensors simultaneously
# - Configurable spike detection ratio (e.g., 2x = power doubled)
# - Minimum threshold to ignore normal low-power fluctuations
# - Optional automatic switch turn-off for safety
# - Derives switch entity from sensor naming convention
#
# Naming Convention:
# The blueprint assumes sensors follow the pattern: sensor.<name>_power
# and the corresponding switch is: switch.<name>
# Example: sensor.coffee_maker_power -> switch.coffee_maker
# =============================================================================

    Monitors power sensors and triggers when consumption spikes beyond a defined
    ratio compared to the previous reading. Optionally turns off the associated
    switch for safety. Assumes naming convention: sensor.<name>_power -> switch.<name>
