The E20 ethernet reader is designed on DSMR 5. When using it on a DSMR 5 supported meter, it will be powered parasitair via the P1 port. When connected to an older smart meter (DSMR 2/3/4) it will require an external power source via USB-C.
The serial interface is pre-configured for tcp/telnet server use. Therefore it is ready to use in Home Assistant, Domoticz, DSMR-reader and other logging software.
