if you use -t ABCD it will display ABCD or if you use -t stream it will read from the file.
you can specify the file with -T
You can specify the brightness file with -b and it will read form the file when you use --led-brightness=1
Fell free to use/update where ever you want.
if you don’t specify the files, it is reading from:
