#   id / entity : ac_peak_setback  ->  automation.ac_peak_setback_to_82
#   triggers    : 14:00 (id: summer) and 17:00 (id: winter), local time
#   purpose     : Coast through the utility on-peak by setting the AC to 82F.
#
# Self-selecting by season (Pepco MD TOU-P peak windows):
#   * summer (Jun-Sep): on-peak 14:00-19:00 -> the 14:00 trigger applies.
#   * winter (Oct-May): evening on-peak 17:00-21:00 -> the 17:00 trigger applies.
#   A trigger only acts when trigger.id == the current season, so the "wrong"
#   time is a no-op.
#
# Safety: winter is COOLING-ONLY. Heat is gas (not on this electric peak logic),
# so winter never forces cool mode — it only nudges the setpoint when the
# thermostat is already in `cool`. Summer forces cool mode as before.
#
# Fallbacks: workday sensor unavailable -> Mon-Fri (see is_workday).
#
# Setpoints come from the `params` map so summer/winter can diverge later.
#
# v3 (2026-07-09): unified summer+winter, season params map, winter cooling-only.

description: >-
  v3 (2026-07-09). On work days, sets the AC to 82F to coast through the on-peak
  window: summer 2pm (14:00-19:00 peak) and winter 5pm (17:00-21:00 peak).
  Winter is cooling-only (never touches gas heat). Falls back to Mon-Fri if the
  workday sensor fails. Managed in git; see AUTOMATIONS.md.
