Safety, Energy, and System algorithm
Dynamic Cooldown
A frequency-based quiet period after a manual thermostat change.
These algorithms keep the product honest: real Home Assistant commands, real errors, real weather or usage data, and safety-first fallbacks whenever comfort or equipment protection matters.
The short version
A frequency-based quiet period after a manual thermostat change.
What it watches
How many wall touches happened recently inside the touch-frequency window.
How it decides
cooldown = min(MaxCooldownSeconds, BaseCooldownSeconds × recentTouchCount) + a small random quiet delay. More repeated changes mean longer cooldowns.
What it changes
Holds the next correction until the cooldown 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.

Failure modes
If Dynamic Cooldown 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.
