I recently bought a Chinese remote control switch using radio frequency, it's great but has a problem (note I am a newbie), I have a light switch receiving a hot wire only and giving it to the light bulb, the remote control switch has a live and neutral wiring and whenever I try connecting only live wires the remote won't work, what makes it a problem is that I believe the neutral wires are joined inside the wall or hidden in some way. So my question is Can I wire the remote control switch without the neutral wires, note that I tried joining the neutral wires together of course it did not work so the circuit is opened.

Thanks in advance.
