If a stand alone controller would be instantaneous and WIFI connected it would need to be drawing power constantly to maintain a connection. That reduces the practicality of a non plug in unit as the batteries would be constantly draining. We use palm pads as they are portable, require no standby power, and are always ready to send a command instantly. A palm pad that did not repeat dim commands would be nice so you could actually get the brightness level you wanted. If a remote were to be WIFI then the cost would probably be at least $50.00 per remote.
