I have a really old house 20s with knob and tube wiring - there are no wall switches and most of the ceiling fixtures (we still have 3) have knobs on the bulb sockets - about 20yrs ago when we moved in I took a couple of X-10 WS-467 switches and slid them in the ceiling - since then they have worked without any issues and I have been integrating them into various HA systems. Unfortunately one of then finally died and has become unresponsive.
The challange I have have is that the WS-467s are about an inch thick and that about all the room I have without breaking plaster, and every z-wave or zigbee dimmer i have seen is really fat usually 2-3 inches.
Any suggestions - looking for something that is not too fat
