I'm trying to extract readings from a single field on a feed at 12 hour intervals in csv fromat using a restful api GET method. If i use the following call: http://api.thingspeak.com/channels/XXXXX9/fields/4.csv?start=2017-01-01%2000:00&end=2018-01-01%2023:59&median=daily the returned file has a years worth of entries with one reading for each day. I had expected that if I used: http://api.thingspeak.com/channels/XXXXX9/fields/4.csv?start=2017-01-01%2000:00&end=2018-01-01%2023:59&median=720 that I would get a years worth of entries with 2 readings for each day but what I actually get is about a weeks worth of entries with 2 readings per day. I guess that a weeks worth of entries at one minute intervals corresponds to about 8000 data points which is the download limit. The "daily" parameter seems to overcome this restriction but I would like to know if there is a way to overcome the restriction using some kind of half day or quarter day interval. Thanks in anticipation.
