It's not possible wirelessly because Livolo switch doesn't contain a transmitter.However, if you open up the Livolo switch, you'll able to tap on the LED pins on their microcontroller & connect it to Digital Input on Arduino. It's not a very clean solution though.
You should be able to put a volatage/current sensing circuit onto the output of the Livolo switch and have the output of that feedback to your Arduino to know if the Livolo is turned on or off - but natively no there is not any feedback mechanism from the switch itself
