Bottom line is, when your open source-picked thing fails and sets the
building on fire by setting your HVAC to heat instead of cool, what will
you tell the board members?

RS-485 interface is fairly low-level and you can control specific parts of 
the unit via that.

This isn't linux on desktop, kids. This is real stuff. Code fails, things 
catch fire.
