Automatic Update Via Cron

[xxavvv123]

Hello!

I have a cron set to do the following: Upgrade the firmware on midnight on Friday OR Saturday within the date range of 21-28 of every month. I had my cron set to 0 0 21-28 * 5,6. Looks like it's updating every Friday regardless of it's within the 21st to 28th. Looks like the cron logic does not pick that up.

Is there any remedy to this - would a cron via CLI need to be made that uses the upgrade.sh script?

Thanks
