hi, im working with an esp8266-01 for making a relay control and also working with the sensor SCT-013-030, im using the gpio2 for the relay control, and i want to know if i can use de gpio0 for the sensor ? the project is basically turn on/off a 110v lamp, and at the same time calculate the current that is consuming

Also if i need to take some special considerations about the connection between the sensor and the gpio0

thanks!

No you can't :
SCT-013-030 needs analog input , not present on ESP-01 boards.
