Using RoboDyn AC Dimmer with Sparkfun SX1509

Hello,

Is it possible to use Robodyn https://robotdyn.com/ac-light-dimmer-mo … -110v.html with I/Os of SX1509 ?

If Yes, I believe 1 I/O can be used for PWM … Which I/O can be used for Z-C ? Any I/O ? or do I have to use Z-C from the original ESP32 that SX1509 is connected to ?

Thanks so much for your response !

Just to re-phrase my question :

Can any I/O from this board be used for Zero Cross detection ?
