+# Arduino weather station
+
+This is a simple weather station based on Arduino Uno R3 and a TE Connectivity's weather hat.
+
+## Hardware
+- Arduino Uno R3
+- TE Connectivity's weather hat
+- 16x2 LCD display (optional)
+- Raspberry Pi or any other SBC
+
+## Software
+This project has a couple of library dependencies:
+
+#### Arduino
+- [ArduinoJson](https://github.com/bblanchon/ArduinoJson)
+- [TEWeatherShield](https://github.com/TEConnectivity/Weather_Shield_Arduino_Library)
+- [LiquidCrystal_I2C](https://github.com/marcoschwartz/LiquidCrystal_I2C)
+
+#### Raspberry Pi
+- **WireGuard** (optional, used to link a remote Home Assistant instance)
+- **systemd** (used to prepare the environment on the Home Assistant instance)
+- **ser2net** (used to expose the serial port to the Home Assistant instance)
+
+## Installation
+1. Flash the Arduino with the `vremenska-postaja.ino` sketch or flash the included `build/vremenska-postaja.ino.hex` binary.
+
+2. Set up **ser2net** on the Raspberry Pi. The configuration file is located in `ser2net.conf`. The default port is `2000`.
+
+3. Set up **WireGuard** and link the Raspberry Pi to a remote Home Assistant instance. (Optional!)
+
+4. Set up **socat-remote** service on the Home Assistant instance. The service file is located in `socat-remote.service`.
+
+5. Add the `weather_station` platform to your Home Assistant instance. The configuration file is located in `configuration.yaml`.
