If configured appropriately, the display can list 4 new (Firmware ≥ M23)
items intended to allow the consumer to easily monitor energy flow:

The resolution of these 4 displays is 1 W.
Import and Export Energy meter display:
These registers (St1 and St2) are counting energy permanently. The Import
and the Export energy Meter values can be reset by applying a long button
press whilst the register value is being displayed on the meter (working like
a trip recorder in a car).
During power outage registers St1 and St2 are reset. These both registers
start after recover of power with the values of the energy registers of import
or export energy (St1: import, value register 1.8.0; St2: export, value
register 2.8.0).
24 hour and 1 week consumption registers:
These registers show the energy consumed during the last period of 1
week (24 h register: period of 1 day).The meter counts the time duration
continuously but does not synchronise with a calendar clock.
Time during power outages is not included in the elapsed time
measurements of the registers "24 Hour Energy Consumption" and
"1 Week Energy Consumption".
E.g. for the 24 h register assume registration for 5 hours followed by 1 hour
power outage. Then completion of the 24 h registration will complete 19
hours following the end of the outage (5 h + 19 h = 24 h).
After resumption of power following an outage, the registers "24 Hour
Energy Consumption" and "1 Week Energy Consumption" will display "0"
until the first refresh occurs (i.e. after 5 min and 1 hour respectively).
Pulse output LEDs – one for active and one for reactive energy – are used
for meter testing. They transmit visible red pulses equivalent to the
