I'm getting ready to start installing my M1 and I'm getting a little confused by the RS-485/Home Run wiring. Do I really need 18-20g conductor? It looks like Home Depot carries 18-4 shielded cable. But, the 22-4 is about half the cost. My initial install will have a run from the basement to the attic, call it 50' max. In the future, there may be a run to my detached garage, which would be 150'-ish. Recommendations?
