You can enable cron under
Libreelec Settings->Services
Its always useful to familiarize yourself with a new system by going trough all the settings. Its a good way to learn its functions.
I had this enabled, but recevied strange message. Disabled and enabled it again and now it's working, thanks! 
I'm also looking to shutdown my pi during the night, bit I'm not able to configure cron. Crontab -e is not doing anything. It seems to be located in usr/bin. Do I need to enable it somewhere?
Is it possible to install Hyperion Ng on LibreElec Running on a Pi3?
Can't find any installation instructions.
Is it possible to install widevine manually? Or will it be installed via the inputstream.adaptive addon?
I downloaded the following files and placed them under .kodi/cdm, but can't play anything (should I use 32 or 64bit?)
edit: I installed the netflix addon and let this deal with all widevine stuff. it's working now!
