DEVLOG #02

The monitoring loop now takes exactly one Guider 2S camera snapshot per minute and can switch on the printer light when the image is too dark.

I connected the app to Home Assistant’s Core API and configured light.cab_guider_ii_series_light as the automatic camera light. The app measures the configured ROI, and when its 75th-percentile luminance falls below 45/255, it turns the light on for the next scheduled snapshot. It does not immediately retry the dark frame, so the one-image-per-minute limit remains true.

The most important decision was keeping the one-image limit even when the first frame is dark. The tricky part was that changing the app’s default interval did not change the existing Home Assistant option, so I updated the stored option from 5 to 60 seconds, restarted the app, and verified that version 0.1.3 is running with poll_interval_seconds: 60.

This milestone proves that the new lighting and cadence configuration is released on main, and all 16 automated tests pass. The printer is currently off, so the camera/light behavior is not yet live-validated. Shadow mode, phone notifications, and printer decisions remain disabled.

Next: turn the printer on, verify the app-container camera connection and dark-frame light response, then complete two full shadow-mode prints before testing the phone notification and controlled pause/continue flow.
