I have several rooms in my house with no light switches, just pull-chains from the ceiling-mounted fixtures. I want to put switches near the doors, so we don't have to fumble for the chain in a dark room. It's easy enough to put wirelessly-controlled light bulbs in the fixtures, the the problem remains of putting a switch on the wall, so we don't have to use apps to turn the lights on/off. I figure it should be easy to put a Z-wave or Zigbee on/off switch where I want it, and use the (forthcoming) automation features of the Almond to make that switch turn the lights on/off. But I can't find such a switch, all the switches I see assume they're going in place of a wired switch, and require the wiring for power (and directly control the load, rather than just reporting the button press to the controller for handling).
Can any one point me to a simple, battery-powered wireless switch, that is reasonably priced? I thought I saw such a thing recently, just a single-button Z-wave or Zigbee controller, but I can't find it now.
