Exchange a Dimmer Switch for Remote Switch

Question

I currently have 4 energy saver bulbs running on one dimmer swtich.

I would like to change the dimmer switch for a remote switch, like this one: https://www.amazon.com/gp/product/B08CXCHFYC (DEWENWILS Wireless Light Switch and Receiver Kit).

The remote unit is rated for 1000W capacity, so it think its safe and my 4 bulbs, but wanted to be sure.

As well, the remote unit has 4 wires (black, white, blue and red). I would be very grateful for advice how these colors be attached to my existing wiring? Pictures below.

Answer 1

To answer your question in the simplest sense, yes you certainly can replace a switch (dimmer or otherwise) with a remotely-controlled switch.

However, you absolutely should not use the device you have linked. As stated in the other answers and comments, that particular device is poorly designed, probably unsafe, and definitely something I would never want to permanently connect to my mains wiring.

Use a UL-listed, approved remote switching system from a well-known brand of switching devices. For example, the Lutron Caseta system does exactly what you want (not a specific product recommendation - just an example). Lutron Caseta Wireless Switches Product Site

I'm sure the other large lighting and switching manufacturers have similar products - Leviton, Hubbell, etc. I just suggested Lutron as an example because I've used a lot of their products in the past.

Best part: in addition to having to prove that their devices are designed to not burn your house down, a switch or dimmer from one of those manufacturers will also come with instructions that don't require interpretation or force you to do anything contrary to the electrical code.

Answer 2

Should not be to hard. The black and white of the new switch connects to the black and white of the power cable. The blue and red of new switch connects to the black and white of the cable for the lights.

You also have at least one ground not connected, not good, should be connected to the other ground wire at least. Should have the old switch grounded also if it has ground screw, usually green.

You will need to determine which cable is the power and which is for the lights. A non contact voltage tester might tell the power wire from the switched(lights) with the power on and the dimmer off, but can be iffy, might read power on the off wire.
