What do you see here?
The charts to the left are clickable. Just click on the bars of the yearly, monthly and daily usage charts and you can drill down to any day you wish and see the hourly power usage!
In our meter cabinet i have a DIN rail mounted kWh-meter. With this meter the total power consumption of our house is monitored. The meter gives a pulse for every Wh that is consumed. These pulses are being counted by a RFXCOM RFXMeter with a RFXPulse module.
