Hello im trying to defined the two values that comes from each counter, but there isn´t a topic so the Function doesn´t know which value to use. What i want to do is simple, in the Function node i need to do a simple calculation with the values that comes from the two counters, but i can´t create a variable "var on=payload.counter1 " and "var marcha=payload.counter2".
I created a function where i defined a variable to each payload that comes out of the counter, and then i have a FUNCTION where i try to call the variables of each function but still is undefined.
Im new in node red, hopefully some of you could help me out!
