HomeStation

• Bored of constantly looking at your phone to check time and weather?

• Looking for a way to enhance quality of your life?

• Have a spare Raspberry Pi and HD44780?

Build yourself a small weather-home-station!

You'd still have to constantly check time and weather, but at least now on a professional-grade HD44780 screen.

Photos

A photo of HomeStation in real life - at a window sill of mine:

The application in the photo is running with Polish language enabled - it says Overall state: :-))).

Features

• Shows current date (amazing!),

• Shows current time (even more amazing!),

• Heck, it even shows current temperature, pressure and humidity!

• Moreover - shows the PM2.5 and PM10 levels, and overall air quality (easily extendable, if you want to fiddle with it).

Thanks to Airly!

Compiling

To compile, you'll need:

• Rust (tested on 1.26.0),
• Cross-compiling environment (https://github.com/japaric/rust-cross),
• Cross-compiled OpenSSL (unless you plan to compile on a Raspberry Pi itself).

The compiling process is as simple as:

$ cargo build --target=arm-unknown-linux-gnueabi

Then you need to copy the executable onto Raspberry, configure it (see next header) and voilà!

Since during the development one usually does a lot of compiling and copying (at least I have), I've created a simple script which simplifies this process (make.sh + make-config.sh.example) - you don't have to use it, unless you plan on deploying this application frequently.

Configuring

HomeStation needs a simple configuration to work - you have to create a config.hjson file in the application's directory with following structure:

{
  apis: {
    airly: {
      key: "...",
      sensor_id: "...",
    },
  },

  devices: {
    lcd: {
      i2c: {
        device: "/dev/i2c-1",
        address: "39",
      },
    },
  },
}

You can leave the Airly configuration empty, if you don't have a key (although I highly encourage you to create a free account at their site and receive one, if you're from Poland).

After configuring, execute ./home-station and watch the show.
