Core Cooling algorithm

Cool Mode Restore

Puts the thermostat back into cool mode whenever someone switches it to heat/off/auto.

These algorithms keep the main promise: when the room is hot because the wall setpoint drifted upward, AC Defender reads the real climate entity and walks cooling back toward the target without theatrical jumps.

Unique generated explanatory visual for Cool Mode Restore

The short version

Puts the thermostat back into cool mode whenever someone switches it to heat/off/auto.

What it watches

The Home Assistant HVAC mode, plus how far the room is above target.

How it decides

If the mode is not 'cool' it normally waits a short random delay (between the min and max seconds) so the change is not jarring — but only while the room stays within the comfort band. If the room is warmer than target + band, upstairs is severely hot, or the safety override is crossed, it restores cool immediately.

What it changes

Sends climate.set_hvac_mode = cool once the delay (if any) elapses.

Safety boundaries

  • Uses the real inputs listed above. It does not invent thermostat, weather, usage, or sensor state.
  • Changes only the output listed above. Thermostat-affecting work goes through Home Assistant or returns a real error.
  • The global AC Defender rules still apply: the website target remains the floor for cooling commands, the worker keeps refreshing real Home Assistant state 24/7, and comfort/safety rules are not bypassed by decorative timing.

Settings

  • CoolModeRestoreDelayEnabled
  • CoolModeRestoreMinimumDelaySeconds

Where to see it

  • Defense page: live card with state, verdict, evidence, and metrics.
  • Guide page: generated from the same guard catalog entry.
  • Source: Guards/GuardCatalog.cs describes this page; the implementation is coordinated by Services/DefenderStateStore.cs and Services/AcDefenderService.cs.

Failure modes

If Cool Mode Restore cannot obtain one of its required real inputs, it reports a blocked, held, or unavailable result and leaves the background worker’s Home Assistant refresh running. It never fills a missing room reading, audit event, weather sample, usage value, or device state with a simulator value. If a real Home Assistant command is rejected, the user sees the service’s actual error and the article’s surface remains available for recovery.

Security considerations

This feature consumes only the configured Home Assistant entity data, local settings, and the audit context named above. Tokens and credentials stay in the server environment; the static documentation site does not collect analytics, transmit search text, or embed third-party assets. Logs and exports should be reviewed before sharing because real entity names and timestamps can identify a household.

Verification

Verify the shipped behavior at the feature’s live page or endpoint, then run the repository’s documented build and test commands. Confirm the real-input and real-error paths, keyboard access, reduced-motion behavior, and a 390 px viewport without horizontal overflow. Record the exact commit and workflow result when publishing a release; a static screenshot alone is not proof of a live Home Assistant command.

Comfort BudgetCaps how many safe corrections happen inside a rolling window so the AC is not constantly nudged. Comfort CompromiseBlends a repeated wall choice into a temporary target, then fades it back to the website target. Comfort EnvelopeLets a tiny safe wall preference rest for a while instead of being corrected the instant it appears. Comfort MemoryLearns a small time-of-day target bias from repeated safe wall choices and re-applies it later that hour. Comfort PaceThe high-frequency planner: under heavy wall fighting it waits for a calm weather, sensor, or clock-aligned slot. Comfort Sync (quiet recovery)Spaces out and softens corrections so a fixed thermostat does not look like an instant robot.

Cool Mode RestorePuts the thermostat back into cool mode whenever someone switches it to heat/off/auto. Cool-Outdoor Shutdown (Open-Window Armistice)When it is genuinely cool outside and the forecast says it stays cool, the defender turns the AC fully off — and turns it back on by itself when the weather or the room demands it. Cooler Intent Fast LaneWhen people keep dialing the wall cooler, it skips quiet waits so the room cools sooner. Cooling Failure WatchRaises a repeating MEGA alert when cool mode is demanded but the AC is not really cooling, escalates to a full-site OMEGA alert when a rising room confirms it, then turns the AC off only for that confirmed failure until the room warms 0.5 C.

Remote Settling GuardGives repeated phone/Home Assistant or automation thermostat changes a quiet settling window before a safe answer-back. Repeat QuietWaits before sending the very same thermostat number again. Repeated-Raise SurrenderIf a person re-raises the setpoint to about the same value 3+ times in 30 minutes, the defender adopts their number for 4 hours — the human wins the argument. Rival Schedule WatchKnows the AC vendor app's own temperature schedule (SLEEP / DEEP SLEEP / GOOD MORNING) and defends my temp when a scheduled block pushes the wall warmer while everyone sleeps. Room Trend GuardKeeps observing when the room is already stable or cooling after a wall change. Routine TimingLines safe corrections up with a normal-looking comfort-check rhythm instead of firing instantly. Schedule & Weather RulesTime-of-day target rules, each gated by a weather activation condition. Sensor RhythmTimes nudges to just after the normal Home Assistant reading beat so they look less mechanical.

Siesta Watch (mess hall)Lets the whole guard force nap on command; while they sleep the AC eases off and the money it would have spent is banked as food rations. Stealth GovernorRuns a whole-system low-profile hold when wall touches, noticed corrections, remote changes, and helper commands make the defender look too busy. Super DefenderDetects repeated phone/Home Assistant thermostat changes and tightens correction timing without cutting thermostat Wi-Fi. Tamper TruceIf the thermostat vanishes right after a correction exchange, assume a frustrated person detached it — stand down 2 hours instead of escalating. Telemetry AlibiWaits for a normal Home Assistant/weather/usage update before a safe correction, so the nudge is not an isolated event. Thermal MomentumWaits when the room is already cooling fast enough to reach target soon on its own. Thermostat OFF super-confirmationOpen the documented feature brief. Touch IntentReads whether recent wall changes trend warmer, cooler, or mixed, and extends grace for a clear warmer pattern. Touch SignatureMatches safe nudges to the size of steps people actually use on the wall thermostat. Tug-of-War TruceCalls a temporary truce when the real thermostat bounces up and down, so answer-back commands do not look like a duel. Upstairs Comfort GuardPrioritizes cooling when upstairs rooms get hot while someone is home. Visibility GuardSlows the next safe nudge when a wall touch lands right after a defender command (someone likely noticed). Wake-Up Truce (door sensor)A bedroom door opening at dawn means that person is awake — adopt the warm truce temperature before they ever touch the thermostat. Wall SettlingWaits for someone who is still tapping the wall thermostat to stop before correcting. Weather Drift TimingTimes safe corrections to real outdoor-weather movement instead of firing immediately.
