For your relay issue....

Then, go and install Jon Welfringer's simulator patch to gain control of RFX from PEP2.

Here is the info I received earlier from Jon Welfringer's Simulator to RFX enhancements.

The RAR file can be downloaded from the following link:

[Link: welfringer.com]

Please review the README.txt file included for information on setup.

This basically is a man-in-the-middle that will enable your pronto simulator to talk to RFX for Relay commands but you MUST use fixed IP on all your extenders for this to work properly.

For your IR command issue...

With regard to routing an IR command to an IR port, you will need to create 3 duplicate components under building blocks (Fan1, Fan2, Fan3). It is at the component level where you can assign the component to an RFX and then once on an RFX, assign the proper IR port.
