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
# Example configuration.yaml entry media_player: - platform: nad serial_port: /dev/ttyUSB0
serial_port (Required): The serial port . Default is
- name (Optional): Name of the device. Default is NAD Receiver.
min_volume (optional): Minimum volume in dB to use with the slider. Default is
max_volume (optional): Maximum volume in dB to use with the slider. Default is
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.
A full configuration example could look like this:
# Example configuration.yaml entry media_player: - platform: nad serial_port: /dev/ttyUSB0 name: NAD Receiver min_volume: -60 max_volume: -20 sources: 1: 'Kodi' 2: 'TV'
