onsetState function

[astrowalker2013]

Hi,

I want to used dynamically the onSetState function of the library.
i explain,

in my case we add dynamically the device, ( we create a little OS to comunicate with esp32 by telnet or serial), in this case is it possible to used onSetState after each call of add device without lost the previous callback write.
is it possible de create a pointer of callback ?

Best
