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.
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.
