Since the I3/I4 inputs can be set to analog. They have no pull up resistors on them. So an internal one is not in the design.
I have seen posts indicating if you do not use I3/I4 to wire them to the ground pin to prevent the chatter and constant Insteon broadcasts.
Folks using an ISY controller would also see constant chatter if the Analog/Digital Inputs of any EZIO model with them left them floating.
