Yeah I'm way more available when working from home, since I can get my nicotine fix at my desk and I can't do that in the office. I need to get up and walk around to get the blood flowing, in the office I think it would be weird to walk a few laps around the cubicle to do this, so I end up being further from my desk more. At home I'm basically always close enough to hear my computer make a ding when I get a message. And if there's an urgent issues that requires attention off hours... sorry not much I can do to help you when I'm on a bus transiting to and from work.
