## Utilities
|
||
|
|
|
||
|
|
This folder contains a set of utilities that may become usefull when working with wmbusmeters.
|
||
|
|
|
||
|
|
### Analyze.java
|
||
|
|
|
||
|
|
A utility to analyze telegrams.
|
||
|
|
|
||
|
|
### XMLExtract.java
|
||
|
|
Deciphers and prints out the content of encrypted XML file. The encrypted file must use W3C XML Encryption Recommendation with [128bit AES-CBC cipher](http://www.w3.org/2001/04/xmlenc#aes128-cbc).
|
||
|
|
|
||
|
|
**Usage:**
|
||
|
|
|
||
|
|
java -cp . XMLExtract [password] [encrypted_xml_file]
|
||
|
|
|
||
|
|
### kem-import.py
|
||
|
|
|
||
|
|
Extracts meter information from Kamstrup KEM file and imports meter files to wmbusmeters' config folder.
|
||
|
|
|
||
|
|
The KEM file is a (sometimes zipped) xml file that contains xml-encrypted data using the [xml-enc standard](http://www.w3.org/2001/04/xmlenc). The password needed to decrypt the xml-encrypted data can either be the CustomerId or something else selected by the person that has created the KEM file using Kamstrup software.
|
||
|
|
|
||
|
|
The script takes the encrypted KEM file and decrypts its content (it automaticly detects if the file is a zip archive and extracts the kem file from it). The result is a XML with a list of meters with their types, serial numbers, keys, etc. The script prints the information about each meter to the console and populates wmbusmeters' config folder with corresponding meter files.
|
||
|
|
Optionally, decrypted KEM file content can be saved to a file.
|
||
|
|
|
||
|
|
**Usage:**
|
||
|
|
|
||
|
|
python kem-import.py [options] <kem_file> <password>
|
||
|
|
|
||
|
|
Use -h switch to get the full list of options or see the source file for more info. If you want to import to system's config folder (`-c /etc` switch), you neet to use sudo (`sudo python kem-import.py ...`) to get write access to it.
