*hwmon-path-abs*: ++
typeof: string ++
The path of the hwmon-directory of the device, e.g. */sys/devices/pci0000:00/0000:00:18.3/hwmon*. (Note that the subdirectory *hwmon/hwmon#*, where *#* is a number is not part of the path!) Has to be used together with *input-filename*.
This can also be an array of strings, for which, it just works like *hwmon-path*.
*input-filename*: ++
