Average power consumption is not displayed on your smart home device
The average power consumption values to date are not displayed for a connected smart home device, such as FRITZ!DECT or the FRITZ!Powerline adapter, 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. To display a forecast of consumption, the device must be in continuous operation for two entire consecutive days (from from midnight to midnight) so 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.
