The nad platform allows you to control a NAD receiver through RS232 from Home Assistant.

To add an NAD receiver to your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
  - platform: nad
    serial_port: /dev/ttyUSB0
    name: NAD Receiver
    min_volume: -60
    max_volume: -20
      1: 'Kodi'
      2: 'TV'

Configuration variables:

  • serial_port (Required): The serial port . Default is /dev/ttyUSB0
  • name (Optional): Name of the device. Default is NAD Receiver.
  • min_volume (optional): Minimum volume in dB to use with the slider. Default is -92
  • max_volume (optional): Maximum volume in dB to use with the slider. Default is -20
  • sources (Optional): A list of mappings from source to source name. Valid sources are 1 to 10.

The min_volume and max_volume are there to protect you against misclicks on the slider so you will not blow up your speakers when you go from -92dB to +20dB. You can still force it to go higher or lower than the values set with the plus and minus buttons.

On linux the user running home-assistant needs dialout permissions to access the serial port. This can be added to the user by doing sudo usermod -a -G dialout <username>. Be aware that the user might need to logout and logon again to activate these permissions.
