Need to Understand how to Parse Data (Maybe)

#1

1) Give a description of the problem
I don’t know how to do this so its less of a problem and more of a request for help. This is what I would like to do, I’ve created a series of weather variables such as temperature forecast and rain forecast (over 10 days). I want to take only the next 3 days of data (not the entire 10) and based upon that data create conditions that would turn on my pool heater to give it time (overnight) to warm the pool

2) What is the expected behavior?
For instance, If at 5pm every Thursday and if rain for the next 3 days <= .5 in then turn on pool heater.

3) What is happening/not happening?
I simply do not know how to parse out the data (JSON might as well be a foreign language to me).

Your variables can be accessed with the arrayItem() function. arrayItem(0, high) is today’s high temperature, arrayItem(1, rain) is tomorrow’s rain in inches, and so on. To get the total rain for the next three days you can use the expression sum(arrayItem(0, rain), arrayItem(1, rain), arrayItem(2, rain)).
