Hello everyone, I am new in this forum, I just start using thingspeak with some RPI (2) to monitoring the internal CPU temperature. I use a Python Script that I found in internet. Just changing the number of the fields, each RPI appears on a different field. So that means that each RPI is using the same API code in the Python program and just changing the number of the field, it shows the data in one or the other field. Is working fine, but on reboot one of them is not sending data at all, I have to run the python manualy even if is on a cron job. They reboot every day at the same time whit a external timer. I would like to ad more RPIĀ“s to this channel whith the same python program

Do I have to put each RPI on different channels or is OK doing it like that?

Thank you from Costa Brava, Spain

The rate limits for writing are per channel. So if you have two or more devices asynchronously writing to the same channel, there is a possibility for collisions, which means the second device data will be lost. The recommended model is one device per channel.
