Global Cache iTach WF2IR or IP2IR

[Sirhideo 9]

Hi, I am planning to replace all my Remotec ZXT-120 and use Global Cache product. I would like to make sure a few things before I make the purchase.

 

I have 2 exact same brand, same model, same IR remote window type IR operate Air-Conditioner installed in 2 different rooms.  I use 1 ZXT-120 for each air-con, no problem.  Since iTach will become a centralized IR controller, when the let's say Turn On command is sent out from the 3.5mm jack, are both Air-Conditioner gonna execute?  If so, how can I setup iTach so that I can define Air-con A and B?

 

Another thing is regarding the 3.5mm IR cable, iTach will be sitting in living room, so obviously it cannot shoot through wall so that both of my air-con can hear the command.  I would like to know if there is any IR blaster/extender that extends IR signal wirelessly.  Yes, I found Sewell BlastIR wireless version, I'm actually using it to control my soundbar with harmony.  However, the sad thing is that the receiver side, i.e. both rooms, does not have electric supply ...  Is there any product out there that is an wireless Emitter and receiver combo, but the receiver is battery powered (CR2032 perhaps) ?

Thanks
