# ac_peak_setback — let the house drift during the utility peak window
#
#   id / entity : ac_peak_setback  ->  automation.ac_peak_setback_to_82
#   trigger     : 14:00 local (America/New_York)
#   purpose     : On work days, set cool 82F to coast through the 14:00-19:00 peak.
#
# Graceful degradation (v2):
#   * workday sensor unavailable/unknown -> fall back to a plain Mon-Fri check
#     (a broken holiday sensor must not silently cancel the setback).
#   The original used a blocking `condition` on the workday sensor, which would
#   skip the run whenever the sensor was unavailable; that is the bug this fixes.
#
# v2 (2026-07-09): workday fallback added. See AUTOMATIONS.md.

description: >-
  v2 (2026-07-09). At 2pm on work days, sets the thermostat to cool/82F to coast
  through the 2-7pm peak. Falls back to Mon-Fri if the workday sensor fails.
