Welcome to the NetDaemon project!

NetDaemon is an application daemon that enables you to write powerful home automation scripts in C# for Home Assistant. This repository contains **NetDaemon V5**, the latest version of the framework.

## About NetDaemon

NetDaemon was founded by [@helto4real](https://github.com/helto4real) in 2020 as a personal project to explore the use of C# in Home Assistant. Early contributions from [@Ludeeus](https://github.com/ludeeus) helped integrate NetDaemon with Home Assistant. The project gained significant momentum when [@FrankBakkerNl](https://github.com/FrankBakkerNl) joined and introduced the HassModel API, which leverages code generation to create a user-friendly experience.

Currently, [@helto4real](https://github.com/helto4real) and [@FrankBakkerNl](https://github.com/FrankBakkerNl) serve as the primary maintainers, though many others have contributed over the years.

## Getting Started

To learn how to install and use NetDaemon, visit our official documentation:

[🔗 Getting Started Guide](https://netdaemon.xyz/docs/user/started/get_started/)

## Usage

NetDaemon allows you to write your automations easily and cleanly using C#.

```cs
[NetDaemonApp]
class MyApp
{
    public MyApp(Entities entities)
    {
        LightEntity hallwayLight = entities.Light.HallwayLight;
        BinarySensorEntity motionSensor = entities.BinarySensor.HallwayMotionSensor;
        
        // Check state of entities directly
        if (motionSensor.IsOn() && hallwayLight.IsOff()){
            hallwayLight.TurnOn();
        }

// Subscribe to changes in the state of the motion sensor
        motionSensor.StateChanges()
            .Where(e => e.New?.IsOn() ?? false)
            .Subscribe(_ => hallwayLight.TurnOn());
    }
}
```
