To increase the information about power / energy consumption in my house I would like to track as well the power consumption of my fritz!boxes and fritz!repeaters.
Hence, I would be very happy about a sensor that provides information about the power consumption.
Ideally absolute values (W) would be perfect 
The Fritz! GUI shows percentages (%) but not absolute values, but percentages would be ok as well. For this I would take some datapoints using a powermeter (socket) and create a sensor using PowerCalc integration.
