can I control one axee I/O from other xbee?

Hello all,
I am trying to understand how to control several Xbee’s I/O with a single xbee connected to a computer.

One more issue I have is wifi xbee.
For exmaple this module:

Can I connect to a wifi network and also to xbee series 2?

Thank you.

No you can’t connect a WIFI module or device with an XBee ZB module as they are two different protocols and standards.
