Connecting the Smart Tuya Wi-Fi switch to the power supply for desk top control

Hi,
I would like to connect a smart Tuya WI-FI switch under a power supply to install such a switch in a desk top. Obviously, no lighting will be physically connected to it, it will only be used for WI-FI control.


Can this be done?

Do you want to control the power supply with such a switch?

Under which power supply?
Since nothing will be connected to it, how will it control anything?

I may have written imprecisely.

At the moment in some rooms I have such a switch connected to the main lighting, plus two connectors in the switch are unconnected. Using the smart life app, I have programmed them so that, for example, in the bedroom, one button turns off the lighting throughout the house.

I thought it would be nice to have such a switch in the desk to control the lighting. Nothing will be physically connected to it, everything will be controlled by automation in smart life.

When connecting the power supply I am concerned with providing it with the necessary voltage for the smart function. I do not want to control the power supply .

What power supply since it runs on mains voltage?

That is, you have L and N (phase and neutral wire) available at the switch connection point. This simplifies things, you don't need to use any additional load in the form of a lamp or power supply.
Connect L and N to the switch, don't connect the lamp - program and control This is the connection as on the left of the picture from your first post" with neutral".
Maybe it would be easier to use a "Tuya remote control"? I have these battery-powered quadruple and triple in a housing resembling wall switches, but I also have one in a small housing the size of a gate remote.

Thanks that's exactly what I meant
I have a few switches left, hence the idea.

Add Amazon Alexa to the mix - you won't have to 'search' for the switch. Especially useful for turning off lights .
