I apologize in advance if this is a real journeyman question but can you explain the idea behind the digit in the center of the RF sensor icon? I'm not sure what it means and I don't seem to see it change. I am using Home Genie (thank you for such a great product!) with a RaspPi just fine with some old RF X10 security window/door switches but this icon oddity has me perplexed.
Thanks for any help you might offer!
