The receiver XBee is sitting on a MacMini in a corner, behind the lovely jasmine:

The transmitter is only about 15 feet away, outside, enclosed in a plastic container and a ziploc bag, held in place by a soapstone rhino that has seen its share of Chicago winters:

The range on this setup is terrible. Nowhere near the ‘300 feet’ range that some literature suggests for the Series 1 – my signal is dropping to borderline if I move the transmitter 20 feet farther out onto our terrace. Don’t know what the problem is yet…

Maybe I’ll add the signal strength to the Cosm feed.
