Hello!
I'm looking for a DLMS/Cosem library which handle the communication to an eletric smart meter. We want to read some parameters like voltage, current and power consumption.
Now we have the problem that the incoming data over the P1 port are encrypted. I have taken a look in your cpp library and saw that there are decrypt functions available but the decrypt part for his own is not implemented. Is there another version where this part is implemented? Commercial ones would be also fine.
Maybe someone of you have any information for me!
Thank you so far!

Decryption of DLMS
Hi,
GMAC is using same function to encrypt and decrypt. We'll remove that other block because that is not needed.
Please, let me know if you are interested from commercial version. We can help you better with DLMS protocol.
BR,
Mikko
