Spot on thanks, DIGG3R. Yes, New Timer > Type = Execute Plugin > Time > Daily > then at the bottom is where you select which Plugin to run. First one will be "Reboot" and the second one "AutoBouquets"
As an alternative for the Reboot Plugin, you can also try Timer Type = Shutdown
Testing has shown that since the DM500 cannot actually shut down like the old dBox2 could, deploying this Timer actually REBOOTS the box in identical fashion to rebooting from the Main Menu with the remote.
So for C14.7 we've dropped the Reboot Plugin and renamed the "Shutdown" timer to "Orderly Reboot"
