Can you change the manual light switch into a remote control switch? If possible, how to change it. Solve!

It can be completely changed. If you buy a remote control switch for a light, it will turn on the light when it is energized. A remote control switch is installed in series in the original switch circuit. When you turn on the original switch, the light will come on. At this time, the switch can be remotely controlled, which is very convenient. If you don't use the remote control switch for a long time, you can turn off the previous switch and then you can't remotely control it.

If it is a high-grade remote control switch, please connect it according to the manufacturer's instructions.

Note that when the remote control switch is powered on (that is, it can work remotely), it generally consumes about 0.5W, so please turn it off when it is not used for a long time.
