i like using thingspeak but the problem is,it always save the last data that have been sent by the arduino,so i cant detect if the arduino is truned off
btw im using esp32 ,i already established the connection between the mit app,thingspeak and esp32 .
the problem is the thingsspeak is always saving the last data ,(i also used firebase but it have the same problem)
my initial idea is to detect if the value is zero(not measuring any data) then the mit app will notify the user ,that the arduino is not connected to internet or turned off
but its not possible because it always saves the last data.
my next idea is to use mit app to determine if the last entry is not updating ,
but i dont know how i can do it, i cant also find tuturial to fix my problem xD hahah
