NetDaemon - Write your automations in C# for Home Assistant

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 in 2020 as a personal project to explore the use of C# in Home Assistant. Early contributions from @Ludeeus helped integrate NetDaemon with Home Assistant. The project gained significant momentum when @FrankBakkerNl joined and introduced the HassModel API, which leverages code generation to create a user-friendly experience.

Currently, @helto4real and @FrankBakkerNl serve as the primary maintainers, though many others have contributed over the years.

        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());
