Domoticz

hi guys , i want build a relay with 8 channel for control (work with http://. . . ) and work with 8 key(when key is on / off send on/off to domoticz...)
i build this with 2channel with esp8266. but my sketch dont work for esp32. i am beginner in esp32. any body can design a relay with 8 or 10 channel with 8 or 10 key for domoticz?

If you share your code for 2 relays, then I can look if I can convert it first to ESP32, a later extend to 10 relays.
