# Sia server

Sia server is an Internet of Things (IoT) server. It should be compatible with
multiple devices from different vendors. The user interface should be
implemented by apps connecting to this central Sia server.

## Supported vendors and devices

Currently only [Homematic IP][1] as a vendor and the [OpenCCU][2] as interface
is supported.

The currently only supported device is:

- [HmIP-SWDO-2][3] - optical window or door contact

Further device support is planned.

## Build instructions

The Sia server is built and tested with the Meson build automation tool.

```
meson setup build
meson compile -C build
meson test -C build
```

Build artefacts can be shown with the `tar` archive tool and `less` pager.

```
tar -tf build/sia-server-v*.tar.zst | less
```

All relevant build results are part of this Zstandard-compressed tar archive.

## Usage

On a `linux/amd64` machine the Sia server can be launched with default
configuration in an unpacked deploy archive.

```
./sia-server-linux-amd64
```

The command line interface is documented in the help page.

```
./sia-server-linux-amd64 -help
```

The configuration file format can be looked up based on the
`configs/default.json` file.

The files in the `systemd` folder are provided for integration into
[systemd][4]-based Linux distributions.
