thingspeak send data seperately
Posted: Fri Jul 17, 2020 7:08 pmI want to send 6 temperature values to a thingspeak channel and, 6 other temperature values to a different channel, how do I seperate the second 6 values from the 6 first, and how can I send them to the seperate channel? I got the code to send to one channel but I dont know how to send it seperately.
any help is appriciated
