Hi all,
Maybe is a stupid question but looking on a lot docs found over internet I am still not clear about wiring CD74HC4067 module to esp32. Target is to add a 16 relay to HA using this.
So to which esp32 pins should I connect SIG / S3 / S2 / S1 / S0 / En ?
Thank you in advance

Actually, the chip is bidirectional and could also be used as output, but this is not supported by the component yet.
I pointed to the page already.
