I am trying to modify this program but it is beyond my current knowledge. it is written for the esp8266-01 but i am using a nodemcu. i would like to add other sensors to other gpio ans send different messages depending on which sensor is tripped. for example 2 sump pumps. maybe a simple motion sensor i can turn on while on vacation. if someone could add rem statement to this program or suggest how to do this it would be appreciated. thankyou. and all the credit for work so far goes to random nerd tutorios.
