What is the minimum I need to test the noise level in my house before purchasing a bunch of UPB switches, etc. Can I just plug in a UPB PIM and pull up UPStart? Or do I need a phase coupler and a few switches to determine if it will work? I'm slightly concerned as I have two APC Smart UPS and a Backups RS. I also have a fish tank with an external pump that runs 24/7
