Can't you just unplug it from the USB at night?

Did you read man hdparm in a terminal? You probably want little -y. Not sure if it would wake up on USB if you use capital -Y.

so
Code: Select all
$ hdparm -y
?
do I have to use sudo?

I want to do it via ssh.

You need to specify the device your are putting to sleep. The command is
Code: Select all
hdprm -y /dev/sdx
