Sensor Timing algorithm
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.
These algorithms make corrections land near real house signals instead of on a robotic beat, while still stepping aside when room comfort needs direct cooling.
The short version
A bedroom door opening at dawn means that person is awake — adopt the warm truce temperature before they ever touch the thermostat.
What it watches
The configured bedroom door sensor (closed-to-open transitions) during the dawn window.
How it decides
When the door sensor flips from closed to open between the window start and end (default 04:00-09:00), the defender immediately adopts the truce temperature (default 25 C, never below my temp, capped at 27 C) for the hold period (default 2 h) using the same surrender machinery. The person wakes to a defender that already agrees with them.
What it changes
Adopts the truce target for the hold period and logs a friendly good-morning event.
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 Wake-Up Truce (door sensor) 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.
