Add configurable sleep hours to blank ring light at night#108
Merged
Conversation
Adds led.sleep_start and led.sleep_end (0-23 local hour) to config.json and the led block. When the current local time falls within the window the ring is blanked entirely so it won't disturb sleep. The window wraps midnight (e.g. sleep_start=22, sleep_end=7 covers 10 pm - 7 am). Set either value to -1 to disable the feature. Closes #102 https://claude.ai/code/session_0166Zd59EUgWgYd3FrphQAio

Summary
Closes #102
The ring light stays on overnight, which is bright enough to disrupt sleep. This PR adds
led.sleep_startandled.sleep_endtoconfig.json— a local-time window (0–23 hours) during which the ring is completely blanked.Default ships as 10 pm – 7 am (
sleep_start: 22,sleep_end: 7). The window correctly wraps midnight. Setting either value to-1disables the feature.Changes
