Attempted to install a TPLink Kasa 3way switch in asingle gang box. spent hours yesterday replacing wire into this box to add a neutral. This is now electrically functional but I can't get this sucker all the way in because the box is kinda narrow & shallow, and there are 3 wire nuts behind. I suspect all boxes will be that small - do I give up on this brand of smart switches?
(in a different location where I had a 4 gang box and I only had one of these big boys go in I was able to tuck the wiring nuts behind the neighboring switches)
I'll measure the depth of the wall to see if there's a point in getting a deeper box but if I need to pull that with every outlet I might give up on the project or only do it as I'm about to paint a room.
