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

Please note that the RS232 interface is only tested with the NAD T748v2, but it should work with other NAD receivers. The Telnet interface has been tested with the NAD T787 and the NAD C658.


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

# Example configuration.yaml entry for RS232 configuration
  - platform: nad
    serial_port: /dev/ttyUSB0
# Example configuration.yaml entry for Telnet configuration
  - platform: nad
    type: Telnet
    host: "IP_ADDRESS"
# Example configuration.yaml entry for TCP configuration
  - platform: nad
    type: TCP
    host: "IP_ADDRESS"

Configuration Variables

type string (Optional, default: RS232)

Type of communication. Valid types are RS232, Telnet or TCP

serial_port string (Optional, default: /dev/ttyUSB0)

The serial port. (for RS232 type only)

host string (Optional)

The IP address of your amplifier. (for TCP and Telnet types)

port integer (Optional, default: 53)

The port number of the device. (for Telnet type only)

name string (Optional, default: NAD Receiver)

Name of the device.

min_volume integer (Optional, default: -92)

Minimum volume in dB to use with the slider.

max_volume integer (Optional, default: -20)

Maximum volume in dB to use with the slider.

sources list | string (Optional)

A list of mappings from source to source name. Valid sources are 1 to 12. (for RS232 and Telnet types)

volume_step integer (Optional, default: 4)

The amount in dB you want to increase the volume with when pressing volume up/down. (for TCP type only)

The min_volume and max_volume options 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 higher or lower volumes than the values set by using 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.

An example of a full configuration:

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