I'm just wondering how these devices receive power, when many have no wiring associated with them at all.

The toilets have a sensor that works from a small ultrasonic pulse. The pulse bounces back to the sensor. Usually, the pulse goes out and hits the stall or wall on the other side of the room and this takes a certain amount of time. When a person is at the commode, urinal, or sink for a length of time, the signal bounces back much more quickly as it has much less distance to travel. When the signal returns to its "normal" time, the toilet flushes. Yes, they usually have hidden wires if the toilets are installed during a construction or remodeling project. However, battery models are also available.

I suppose they might use batteries, but I suspect they do have power cables that are simply hidden from view.
They could use the power of the water to generate current too, but that seems more complicated than necessary.
In any case they would not require a lot of power.

auto flush valves operate on dc current from AA batteries.
