extermanl temperature sensor

When I was looking at the hobbit web page a while back, I thought I remember seeing an advertisement for an external temperature sensor device that was network ready and not to expensive. I cannot see this any more or maybe I am mistaken.

Can anyone point me to a unit that is small, easy to mount and not to expensive and that you have used and can recommend.

Thanks

Robert
