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
(string)(Required)The serial port.
Default value: /dev/ttyUSB0
(string)(Optional)Name of the device.
Default value: NAD Receiver
(integer)(Optional)Minimum volume in dB to use with the slider.
Default value: -92
(integer)(Optional)Maximum volume in dB to use with the slider.
Default value: -20
(list | string)(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'
