Writing data to channel using urllib python package
显示 更早的评论
Hello,
I am trying to write instrument data to a ThingSpeak channel using python. I have installed the urllib package and I am using using the urlopen command to write data. I am able to write data for multiple fields (I have shown t1 as an example but I also have t2, t3), however the rate is inconsistent. More explicitly, the time in between data points varies. I have tried different length delays between events, still inconsistent.
Is this because of Thingspeak, or my python script?
c1 = 'https://api.thingspeak.com/update?api_key=__________&field4='
t1 = urllib.urlopen(c1+str(temp4))
t1.close()
sleep(30)

Are you updating each field separately?
Note that each channel can be updated at most once per second (with a paid ThingSpeak license), or once every 15 seconds (with a free license). So, if updating of the different fields in a channel is one field at a time without sufficient delays between each, only some updates will be accepted.
PS: Please do not post write API keys in your code public. These can then be used to update your channel with spurious data. I'd strongly recommend reseting the write API key in your channel.

If you've resolved that, then another reason your rate is incosistent could be device being capacity limited. Are you sure your computer/device running the python code is not being capacity limited (CPU, memory, network bandwidth, etc.) and is not going to sleep?
