Hi,
i have an ebz dd3 smart meter https://www.celle-uelzennetz.de/fileadmin/data/netze_documents/1_Kunde/Messwesen/eBZ_DD3_Betriebsanleitung_Kompaktzaehler.pdf
and i use this BPW 40
https://www.reichelt.de/fototransistor-npn-30v-100ma-0-1w-bedrahtet-bpw-40-p5806.html
because there is no bpw 40 in 3mm
I get only from the EPS8266
"Hello from 00C14A9B, running SMLReader version 2.2.0."

i use the front info interface on the dd3 smart meter.

Please can you help me

What's the exact model of your meter? DD3 - ... - SMZ1*?

Hi,
DD3 2R06 ETA - SMZ1

I try the top interface but nothing change.

Unfortunately, I can't help because I have a different electricity meter. Maybe another user has this kind of meter and could help. Did you try to read the data from the meter directly using a terminal emulator (Minicom, PuTTY, Screen, ...).

Hi, I'm also a CUN customer with the same DD3 meter and the same problem. Have you solved it? I tired the reading head with led and transistor and just the easy transistor version as shown here. Any ideas?
