Update, I see the same thing is reported and acknowledged in the Home Automation section of the forum
In the rules UI, the four buttons on the key fob are listed as Arm All, Disarm All, Panic (True/False), and Emergency (True/False). In the Sensors tab, the house button results in status "Arm Perimeter", and the star button does nothing. I also couldn't save a rule in which I tried to use the true or false state for the panic or emergency buttons. So it seems like the Rules and Sensor's tab are using different info about what the key fob is capable of.
It seems from the sensors UI that at least the first three buttons are single-state (last button pressed is listed state), so I'm not sure what would toggle the true/false state that the rules seems to want (not that I can save such a rule). The Rules I created using arm and disarm list the triggering state as 0 for disarm and 3 for arm.
