    Hello,
    I need to move a light switch to another wall without pulling a new installation. I want to install a receiver controlled by a wireless switch in place of the current switch. The problem is that I can only find receivers that require a separate power supply, and there are only two wires in the switch box whose short circuit turns on the lamp and a separate power supply I am unable to provide.
    My question is: do such solutions exist? Where can I find such a thing?
    Thanks for your help. Regards.

    Maybe instead of a receiver in the box of the old switch, one under the luminaire would be better?

    Unfortunately I have an led lamp under the ceiling to which I am unable to connect such a fixture.

    I have a 433MHz radio controlled switch from China. You can turn on the light from the remote, it works with LED bulbs, no extra wiring required (I only have L in the box, not even N because it's an old installation, everything has been working for 6 months now). I'll throw up what it's about :) just on ali to find the link.

    I have the white switch and remote control from this post.
    There is a choice of remotes to choose from. Anything on 433MHz can be programmed.

    The wireless receiver won't fit under somewhere near the lamp, that's where you'd have power.

    I don't have much space there, it's quite a flat lamp.

    Thanks. And how does it perform? Does it have some sort of battery power, or does it embrace power from connected wires?

    I have a switch for 2 lamps. The connection is L as input and L1, L2 as output to the lamps. A capacitor is included. On my LED bulbs it works without it. Switches illuminated on the perimeter in blue, as you turn the light on the perimeter changes to red. Remote control powered by 2032 batteries as I am not mistaken. Works ok, no problems so far. Battery in remote control still the same after 6 months.

    Chinese. I also have one of these and they work very well, plus there are remote controls in the shape of a simple switch.

Topic summary

The discussion addresses the challenge of relocating a light switch without new wiring, specifically when only two wires are present in the switch box and no additional power supply is available. Conventional wireless receivers typically require a separate power source, which is not feasible in this scenario. A suggested solution involves using a 433MHz radio-controlled wireless switch and receiver system sourced from Chinese manufacturers, which operates without needing a neutral wire or extra power supply. This system can function with only the live wire present, suitable for LED bulbs, and includes a remote control powered by a CR2032 battery. The receiver integrates a capacitor to manage the load, and the switch features illuminated indicators that change color based on the light status. The wireless receiver is installed in the switch box, while the remote control mimics a traditional switch. Limitations include space constraints near the luminaire and the inability to install the receiver under certain LED fixtures. The solution has been reported to work reliably over extended periods without issues.
