How to measure
device power
1. Turn the output off.
2. Reset relative power.
3. Turn the output on.
A few seconds later, measured relative
power is displayed. If the reading is not
stable, temporary turn off any load which
may consume variable amount of power.
Measured rating may be used to set the
nominal power on ‘By output’ page.

Features
Energy monitoring is the first step to
efficient energy usage. Once knowing
how much energy something is using,
one can make a rational strategy for
saving.
Energy by output
Power count - a number how many times
the output is turned on.
Working hours - total number of hours
the output spent in on state.
Nominal power - output power configured
by user. It can be measured by resetable
power meter, or read from the label.
Current power - output power at the
current moment.
Energy today - total energy used from
last midnight, expressed in Watt-hours.
Energy total - total energy consumed by
the specific output.
Energy consumption in last 30 days [kWh]
Bargraph for last 30 days is a quick way to check for an excess consumption.
