Does it allow to display power consumption per hour, day, date, month?
No, the software doesn't support displaying the active power per hour, day , date, or month. I have installed the software and it shows only active power. There is a section on the main interface where the current power consumption is displayed. There is no other way of displaying it except the current one.
