+You need to adapt the identifier string at the beginning of the decoding lines ('0209090c' here) to the code shown in your dump.
+
+To start the dump enter 'sensor53 d1' in the Console, to stop it 'sensor53 d0'. The dump delivers something like:
+
+```
+18:12:11.474 SML: decrypted block: 56 bytes
+18:12:11.476 :>02 09 09 0c 07 e8 0b 0e 04 12 0c 0c 00 ff c4 00 
+18:12:11.477 :>06 00 01 5a b1 06 00 03 db c9 06 00 00 3d 1b 06 
+18:12:11.479 :>00 02 7b e4 06 00 00 00 11 06 00 00 00 00 06 00 
+18:12:11.481 :>00 00 00 06 00 00 00 ba 
+18:12:11.523 :>00 00 00 06 00 00 00 ba 
+```
+
+As long as you don't get this dump, either the interface is not operational or the provided code from your provider is wrong.
+
+Take the first four bytes from your dump ('02 09 09 0c´ here) and adapt the script.
+
+Be aware that the data sent has separator-bytes between the values (`04' and ´06'). And the last line seems repeated.
+
+This is the interpreted dump:
