Installed and Working in Midea 50 Pint Dehumidifier

[JeffFromTheIRS]

Hi! I just wanted to share that I installed this on an ESP32 board and it works just fine with the Midea 50 Pint Dehumidifier, model MAD50C1AWS-A. It auto-detected as Protocol Version v1.

  # 🆕 Optional: Rename display modes to match your device’s front panel.
  # For example, your unit may label these as “Cont”, “Dry”, or “Smart”.
  # These names only affect how the presets appear in Home Assistant —
  # the internal logic and protocol remain the same.
  # 💡 Tip:
  # If any of the modes below are set to "UNUSED" (case-insensitive),
  # that preset will NOT appear in the Home Assistant UI.
  # Use this if your device doesn’t support or respond to a specific mode.
  # For instance, if pressing “SMART”, your unit doesn't change any mode,
  # set display_mode_smart: "UNUSED" to hide it from the UI.
