How do I load apps (like day/night) on the eZLO plus? If not possible then how do I tell a scene to only execute at night?

Hello @rlargent,
If you are using an Ezlo controller, you should be able to add triggers with the operator AND. Please check this topic I created for instructions.
In your case, you will need to add this day/night virtual device to a group with the other triggers and select the option “All events should be met.”
Regards!
