2026.4.3

• Added (Experimental): Dual-frequency impedance support for Xiaomi S400 and compatible scales. A new impedance_mode selector in the integration configuration allows choosing between None, Standard (single-frequency), and Dual-frequency S400 (50 kHz + 250 kHz). ⚠️ The S400 dual-frequency mode is experimental — formulas are calibrated on a single reference point and results may vary depending on your body composition and scale firmware. Help us improve them: #349.
• Added: New impedance_low and impedance_high sensor entities exposed when dual-frequency mode is active.
• Added: Separate calculation_mode and impedance_mode settings. calculation_mode (Xiaomi / Scientific) applies only to standard single-frequency mode. The S400 dual-frequency mode uses its own dedicated formulas regardless of this setting.
• Changed: Calculation modes are now clearly separated by purpose — Xiaomi replicates the Zepp Life / Mi Fit app results exactly, Scientific uses WHO-recommended equations (Mifflin–St Jeor for BMR, Janmahasatian for LBM), and S400 uses Lukaski-based dual-frequency BIA equations.
• Fixed: Migration path from config entry version 2 → 3 now correctly sets impedance_mode based on existing sensor configuration.
