# libSML
[](https://travis-ci.org/volkszaehler/libsml)
[](https://gitter.im/volkszaehler/volkszaehler.org?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
libSML is a library which implements the Smart Message Language (SML) protocol specified by VDE's Forum Netztechnik/Netzbetrieb (FNN).
It can be utilized to communicate to FNN specified Smart Meters or Smart Meter components (EDL/MUC).
### This is the official libSML repo, the original dailab libsml repo on GitHub is dead
### Usage
An example how to use libSML is in the examples directory.
#### Dependencies
Ubuntu
apt-get install uuid-dev uuid-runtime
#### Compilation
make
The resulting binaries are located in sml/lib
#### Debian Packages
[](https://cloudsmith.com)
We now build Debian packages for amd64, armhf and arm64 as part of our releases.
The ones attached to the release are meant for trixie. These and packages for
bookworm and bullseye are also provided through a repository graciously provided by
[Cloudsmith](https://cloudsmith.com).
The setup of the repository is also
[explained by Cloudsmith](https://cloudsmith.io/~volkszaehler/repos/volkszaehler-org-project/setup/#formats-deb).
This boils down to adding a file to /etc/apt/sources.list.d/ containing
```
deb [signed-by=/usr/share/keyrings/volkszaehler-volkszaehler-org-project-archive-keyring.gpg] https://dl.cloudsmith.io/public/volkszaehler/volkszaehler-org-project/deb/debian bookworm main
deb-src [signed-by=/usr/share/keyrings/volkszaehler-volkszaehler-org-project-archive-keyring.gpg] https://dl.cloudsmith.io/public/volkszaehler/volkszaehler-org-project/deb/debian bookworm main
```
(replace bookworm with your current distro) and retrieving the key as a trusted one
```
curl -1sLf "https://dl.cloudsmith.io/public/volkszaehler/volkszaehler-org-project/gpg.21DBDAC56DF44DA1.key" | \
gpg --dearmor > /usr/share/keyrings/volkszaehler-volkszaehler-org-project-archive-keyring.gpg
```
There is also a libsml package that is part of Debian. While the version in
older Debian releases is somewhat outdated the version in trixie is recent.
Other than the project packages the official Debian package has a version
postfix separated by a hyphen (e.g. 1.0.2-3). It has minor differences in
packaging and is maintained as part of the project in the debian branch.
