Bluetooth - Why forge walls to relocate a light switch ? Idea?

Hello, an idea came to me out of laziness, or according to the thought "Ideas are born out of laziness", namely, I need to change the location of the light switch in the block of flats because I decided to install the door so that now when I open it, I have a light switch behind the door, a little silly, but so it is.
I was wondering if there is something like a "clapper" acoustic switch that would work in such a way that I would mount such a switch on the wall in a different place, which would switch on the main light switch via bluetooth?
Is something like this perhaps achievable somewhere as I have not come across it ?
Maybe someone has thought of something before ?
Such a mobile switch, I move it to where it is most convenient for me to switch the light on and off ??
Thanks in advance for your reply.

An example set, for example, from the Zamel Exta Free range. This set is not bluetooth, but an 868Mhz radio.... Switch + receiver with relay output [there are also versions with dimmer]:

Welcome,

I would not recommend Bluetooth.
It operates in the microwave band.
Seemingly very low power but always.
It is enough that there is a lot of wifi and gsm around anyway.

From the predecessor's option there are many companies and it looks interesting.

There is also a second option.
Make it into a remote control.
It doesn't even come out expensive.
Below you have a sample offer:

Thanks for suggesting cool solutions.

Best regards.

Please write what option you have decided on?
