KnxCached

PRE-VERSION

Linux daemon, manage a cache to Knx object, and provide a SCPI interface to managed objects.

Requirement

This daemon need knxd (libeibclient.so need to build, and knxd daemon need at runtime)

Compile

mkdir build
cd build
cmake ..
make

Principle, and difference with linknx

It can be compared to linknx project, but, the goal of this one is to use a more simple programming approach. knxcached only depends to libeibclient; it is writing in a pure c++11 and only for linux. (and optinnaly openssl) It's goal is only a object proxy; it doesn't do data logging or rules. For this tasks, there will be another daemon connected to knxcached. The first will be knxlogerd, in order to store all change in a database. The second will be knxruled; in order to write rules a QML language (QML binding is a very good approach to write rules). All the configuration will be in sources files; not in database, and not generated by a web interface.

Usage

First, you need to generate a configuration file.

/etc/knxcached.conf

# Main server port
server_port=6722

# KNXD configuration
knxd_url=ip:127.0.0.1

# SSL Port configuration
ssl_server_port=6723
ssl_cert_file=/etc/knxcached/server.cert
ssl_private_key_file=/etc/knxcached/server.key
ssl_private_key_password=<PASSWORD>
ssl_ca_file=/etc/knxcached/ca.cert.pem


# Client configuration (for python scrypt)
ssl_client_private_key_file=/etc/knxcached/client.key
ssl_client_private_key_password=<PASSWORD>
ssl_client_cert_file=/etc/knxcached/client.cert
client_decode_file=/etc/knxcached/devices.xml

{{{ openssl genrsa -des3 -out ca.key 2048 openssl genrsa -des3 -out server.key 2048
