Need more information to able to answer this I suppose. What sort of sensors and platform are we talking?
I am fairly sure you need to go through the telldus hardware, unless you have something on your PC that can pick up the sensors frequency.. but I guess not.
I have seen some pretty straight forward examples for PHP and i am currently building a node.js wrapper for the Tellstick ZNet local server API that can be used for reading sensors(and the whole api) if that is of interest
