+**HMS means Health Management System.** Its binary sensor means the Bambu integration
+has one or more printer health notifications, which can include information or
+maintenance messages as well as faults. Tap the status in the upper-right corner
+or the scrolling message above the footer to open the health-details panel. It
+shows the codes, severities and descriptions reported by Home Assistant, for up to
+three current HMS notices, plus print-error details. Scroll vertically for long
+messages and tap Close to return. If more than three notices exist, the panel says
+how many additional notices are available in Home Assistant.
+
+The status uses **HEALTH INFO** (cyan) for information-only notifications,
+**HEALTH NOTICE** (amber) for common/unknown severities or incomplete details, and
+**HEALTH ERROR** (red) for fatal/serious severities. Severity comes from the Bambu
+integration's `N-Severity` attributes. Missing or unloaded messages never establish
+an information-only status. The display does not dismiss or clear printer alerts.
+The [`hms_errors` sensor attributes](https://github.com/greghesp/ha-bambulab/blob/main/custom_components/bambu_lab/pybambu/models.py)
+provide `Count`, `1-Code`, `1-Error`, `1-Severity`, and the corresponding numbered
+fields for subsequent notices. Stale attributes are ignored when the sensor is off.
