Set measure time

Set direction mode

Set start mode

Hold time: 500 ms (button_hold_ms in config.ini) — the same hold stops a running measurement. Switching to AUTO while the device waits for the button starts the measurement.

Set timezone source

Detected from GPS position: UTC+02:00 (daylight saving time).

Set manual timezone

Stored but not in use — the source above is set to AUTO. Switch it to MANUAL to apply this, which helps close to a timezone border where the position-based lookup can pick the neighbouring zone. Only affects the web display (local time on home page and log list) — SD logs and filenames stay in UTC.
