   Hi @larsterje, one method is to add an event handler for Session.MessageReceived or Session.AnalogStateReceived. That works, but it is nice to implement the IObserver<AnalogState> interface along with its 3 methods. Here is a snippet of C# code that might help you. It shows how to setup the analog pin as well as subscribe to the state monitor. You can do what you need with the value in the OnNext method.

   internal class IO_Sample : IController, IObserver<AnalogState>
   {
       private ArduinoSession? Session { get; set; }
       private int AnalogTest;
   
       public void Initialize(ArduinoSession session)
       {
           Session = session;
           Session.SetAnalogReportMode(5, true); // A5
           Session.CreateAnalogStateMonitor().Subscribe(this);
       }
   
       public void OnCompleted() { }
   
       public void OnError(Exception error) { }
   
       public void OnNext(AnalogState state)
       {
           Console.WriteLine($"pin {state.Channel} reads {state.Level}");
       }
   }
