Wall-Touch Response algorithm
Comfort Envelope
Lets a tiny safe wall preference rest for a while instead of being corrected the instant it appears.
These algorithms exist for the exact household fight AC Defender is built for: someone keeps raising the thermostat, but the room still needs to come back to your temperature without starting a visible duel.
The short version
Lets a tiny safe wall preference rest for a while instead of being corrected the instant it appears.
What it watches
The wall setpoint relative to the defender target and how far the room is above target.
How it decides
After repeated touches, if the wall setpoint stays within the accepted range (target ± max offset) and the room is under the safety band, it simply observes for the hold minutes. A setpoint outside the range, a too-warm room, or a direct-cooling need clears it.
What it changes
Suppresses the small correction while the wall preference is inside the safe range.
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 Comfort Envelope 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.
