I am working on a c# code where whenever there is any change in parameters of nest device, a message must be put on the command line. For eg : If the humidity of thermostat changes from 50 to 67. a message must be written on to the console saying "change in humidity". May need to continuously listen to nest device. Can anyone give me a head start like if there are any api's that i should look into?

You can witness the real time updates using FireSharp whenever you change the temperature in the nest simulator.
