Issue 1.2
There are three maximum demands: maximum demand for active import
power, maximum demand for active export power and maximum demand
for active import power (with a configurable time window).
If T is the period and E the energy consumed during this period, then the
demand at the end of the period should be: D = E * 3600 / T
T in seconds, E in Wh, D in Watts.
The demand register associated to the maximum demand (configurable
time) object runs in background all the time. However, the maximum is
updated only during a certain period of the time each day.
