"notes":"Generic live numeric sensor card. Fill template_state with subtitle, tool_name (defaults to Home Assistant GetLiveContext), match_name or match_names, optional device_class, unit, refresh_ms, value_decimals, and optional thresholds.good_max/elevated_max. Set alert_only=true to hide the card while readings are good and surface it only when elevated/high, with optional alert_score_elevated/alert_score_high overrides. The card title comes from the feed header, not the template body.",
