Hi,
I want to calculate the average water flow every 15 mins between 1am and 5am everyday on my channel data.
I need to know if a pump is running during these hour when it shouldn't be.
I have the average calculation working with code below but I cannot find how to only run this on data between 1am and 5am.
any help would be much appreciated.
waterFlow = thingSpeakRead(readChannelID,'Fields',WaterFlowFieldID,'NumMinutes',15,'ReadKey',readAPIKey);
avgwaterFlow = mean(waterFlow);
display(avgwaterFlow,'Average Water Flow');

Hey Charles,
the easiest approach in my opinion is the following.
keep in mind this is pseudoCode (have no matlab at the moment to test):
actualTime = datestr(now,'HH:MM:SS.FFF'))
if(1 am < actualTime && 5am > actualTime)
% do something
end
I will send you the correct code implementation later.

Read in both the water flow data and the date and time data (perhaps by reading your data in as a timetable.) Call hour on the date and time data stored as a datetime array and use that to select the appropriate elements of your water flow data.
