@weltenwort I just got the same reply from Wasser Nord :-/ Did you happen to try the keys posted above? (https://github.com/weetmuts/wmbusmeters/issues/281#issuecomment-849103756) I haven't tried them as I don't have the...
@weltenwort Cool. Would you be willing to post a single example telegram of the payload that you received? I would like to play around with the decryption a bit (but...
I think what you are doing is correct as far as I understand it. I tried to decode the encrypted part manually (in Ruby as example): ```rb require "openssl" cipher_text...
@weltenwort the serial number on my device is a 8 digit number... maybe they used that 4 times as key?!
@zivillian Are you with "Wasser Nord" as well? (just found your other issue https://github.com/weetmuts/wmbusmeters/issues/383 )

So here is a quick and dirty script to calculate all possibilities: ```rb require "openssl" require 'securerandom' cipher_text = ["EBAEEB906AE817B45D3CC6B46A955BAD34DEA47B00F860ACBB6D280069A227B334CEE23006878125BBAD10EDADAD9635"].pack("H*") decipher = OpenSSL::Cipher.new("aes-128-cbc") decipher.decrypt decipher.padding = 0 decipher.iv = ["A5112655687276073939393939393939"].pack("H*")...
@weltenwort I believe one of those is the right key. Can you confirm? ``` 010e4910E66D83F8010e4910E66D83F8 0368d710E66D83F80368d710E66D83F8 040e2d10E66D83F8040e2d10E66D83F8 076a2010E66D83F8076a2010E66D83F8 0d012f10E66D83F80d012f10E66D83F8 1239d310E66D83F81239d310E66D83F8 37257210E66D83F837257210E66D83F8 3d624c10E66D83F83d624c10E66D83F8 421fcc10E66D83F8421fcc10E66D83F8 5464cf10E66D83F85464cf10E66D83F8 59824f10E66D83F859824f10E66D83F8 61d5e210E66D83F861d5e210E66D83F8 62ec0010E66D83F862ec0010E66D83F8 70661c10E66D83F870661c10E66D83F8 763a3410E66D83F8763a3410E66D83F8 80a36110E66D83F880a36110E66D83F8...
@weltenwort Yeah, I tried all these keys last night too and wasn't able to identify a telegram that looked sensible. Would you be willing to share a few more captured...
