Thanks for the response,Lee. 
I may still be in luck... 
I can remotely log into my PC in Calif. 
I do have the 2412-U or whatever that controller is, that I can have a friend connect to a USB port on the remote PC. 
  
If I install the Simplenet remotely on the PC with the PLM connected,and I know the address of the EZRain device, can I set it up with the pump code, and then control the EZRain from my ISY? 
  
Meaning remove the PLM from the setup, once the device is set to use #8 as a pump relay? 
  
I tried to program the ISY with the commands like:"When #1 or #2 or #3, turn #8 ON, else off". 
It seems it wont allow two valves at once. 
I also found some goofy command like: 000xE7 or something. 
I wrote whatever it was down on a piece of paper and ate it with a bowl of milk...that didn't seem to help, but it was filling and had lots of fiber. 
  
I have a Vera2 also. 
I bought it to mainly control my Z-wave Kwikset lock. 
It claims to also handle Insteon, but not easily I suppose. 
I'm in Baghdad working 12x7, and I don't have a whole lot of time to peruse the forums ! 
  
Sorry for the ramble...long day. 
So I guess the main question is: Will the 2412-U interfere with my ISY, or can they run concurrently; and can I use only the ISY once the pump adjustment is made? 
Thanks again for your time!

Now I have to remote into my Vera,then my ISY, then my CCTV, and also my PC! 
  
I want a all-in-one GUI!
