Hello,

There is a little feature within the Admin Center that let you install add-ons via CLI. On a shell change to the installation directory of i-doit, for example "/var/www/html". There is a sub-directory called "admin" with a file called "index.php". With the following command it gives you a short help:

/var/www/html/admin/$ php index.php Usage: php index.php -a installModule -f modulefile.zip [-i mandatorID]

I hope it helps.
Benjamin
