Average power consumption is not displayed on your smart home device
The average power consumption values to date are not displayed for a smart home device, such as FRITZ!DECT or FRITZ!Powerline, under "Consumption" on the "Energy Display" tab in the user interface.
1 Average values cannot be determined yet
The table forecasts your consumption and does not display actual consumption. In order to display a forecast of your consumption, the device must be in continuous operation for two entire consecutive days (from 0-24 hours) so that it can calculate an average and make a meaningful prediction. This means that it may take up to 72 hours before the average values are displayed in the table.
