Setting remotely updated output values

We then only need to trap these events from our main application. We instantiate the IPSO Digital Output smart object as follows:

this.lwm2mClient = new Lwm2mClient("MIoT:Actuator:" + 
  this.deviceId, this.coapEndpoint, 
  new Lwm2mSecurityObject(), 
  new Lwm2mServerObject(), 
  new Lwm2mAccessControlObject(), 
  new Lwm2mDeviceObject("Waher Data AB", "ActuatorLwm2m", 
    this.deviceId, "1.0", "Actuator", "1.0", "1.0"), 
  new DigitalOutput( 
    this.digitalOutput0 = new DigitalOutputInstance(0, 
    this.output.HasValue && this.output.Value, "Relay"))); 

It's then easy to forward incoming changes to the rest of the application by attaching an event handler on the OnRemoteUpdate event we just created:

this.digitalOutput0.OnRemoteUpdate ...
