Can I replace 5v relay instead of optocupling?

Here in asia its 230v rms should i make a capacitor divider circuit or use a step down transformer

  No need transformer just two capacitor divider must be for 230V
  All oter stay same.

    is it ok to to use 4.4uf in the place of C2 for 230v AC supply
    or should i go for another capacitor voltage divider

And why you’ve done optocoupling ???

  To insulate IC from mains. You can find optocupling in SMPS from simple small charger power supply to big power supply.
  In my youth I wasnt able to buy optocupler so I made optocupler. Now is more easy to buy components.

  the photodiode is quite sensitive and to reduce the sensitivity the capacitor5 is placed
