I was just doing this yesterday.
Trying to find an article describing simple devices that use no external power to send a basic on/off signal (TX–only) over wireless (802.11 I think?).
Anyways, it was said to be used for simple applications that send a wireless signal to a receiver when the laundry detergent gets too low. Sort of like Amazon's push button thingies.
