Subnode Template

Upon completion of this topic, you will be able to:

1. Create and run a project using the dotnet new subnode command

---

Create a project

Creates a project with:

• Custom device class inheriting from TcpModbusDevice
• Event-driven architecture (OnDataReceived)
• Ideal for single device development and debugging

mkdir devices
cd devices

# Create a new project
dotnet new subnode -n MyDevice

# If you already have an existing template, use the '--force' option to overwrite it
dotnet new subnode -n MyDevice --force

---

Quick Test

You can execute the template project on a built-in simulator, allowing local development and testing without physical devices.

The simulator emulates device data and interactions, enabling you to validate API endpoints and integration logic before deploying to real hardware.

cd MyDevice
dotnet run

Expected output:

🎉 If you see periodic telemetry data, congratulations! You've successfully created your first SubNode!
