Can the IP Power 9258 set one outlet to OFF then 45 mins later to ON; and do that up to seven times in one/same day?

You can set the schedule for a once a day action and repeat that every day, Monday to Friday and separately Saturday and Sunday. You can also set a delay on an action, so that On or Off won't take effect until a time has elapsed. In addition you can also use Wake on LAN so that a particular MAC address can wake the device up. However it is not possible to time multiple ON/Off actions on the same day.
