Hub reboot URL doesn't seem to work

You are correct. I pasted the wrong script!

For reboot:

Replace:

curl -k -sb $cookiefile https://$he_ipaddr/hub/backupDB?fileName=latest -o $backupfile

with

curl -k -sb $cookiefile -X POST https://$he_ipaddr/hub/reboot

And delete

backupdir=/opt/hubitat/hubitat-backup/hubitat
backupfile=$backupdir1/$(date +%Y%m%d-%H%M).lzf
#
find $backupdir/*.lzf -mtime +5 -exec rm {} \;
