DrFever. Your setup is very clean. My buddy and I are looking to pick up a couple of these. And the end of my current run I'll be adding one along with CO2. I've watched all the videos & could only find one negative comment on the forums. How hard was it to setup the communication module? Will a wireless internet connection work or does it need to be hard wired? It eliminates the need for a separate CO2 sniffer correct?
