Callback method for 2 Fans

[pvoncken]

Hello,

I have the following question:
I have 2 fans pointing to the same calback

Fan_1.onStateChanged(onStateChanged);
Fan_1.onSpeedChanged(onSpeedChanged);
Fan_2.onStateChanged(onStateChanged);
Fan_2.onSpeedChanged(onSpeedChanged);

is there any way to callback:
void onStateChanged (bool state)
void onSpeedChanged (bool state)

and know which HAFan triggered the callback ??
Because now it always triggers Fan_1.

Hope someone can help me with this one.
