Hi,
I have some difficult to post data on channel.
The AP KEY for writing is : XXX
The AP KEY for reading : YYY
When I try to make GET or POST request (from Chrome or Postman) the result is always 0.
I didn't understand why, I follow too tutorial and try with Postman but always 0.
Thanks for your help.
Besy Regards

I'm able to post to your channel using the link specified. Can you try again?
Also, my recommendation is to reset the API key to your channel and update your post above to remove your API key, unless you want spurious data in your channel.

I am also having this issue. no matter what i do, i always get 0
EDIT:
the code responsible for uploading the data looks like this (Arduino Code):
HttpClient client;
humidity = DHT.getHumidity();
temp = DHT.getTemperature();
client.get("https://api.thingspeak.com/update?api_key=XXX&field1="+String((int)temp)+"&field2="+String((int)humidity)+"&field3="+String(dewPoint((int)temp, (int)humidity)));

Hi everybody
I created 3 channels, humidity - temperature - altitude. (channel ID 979451)
Using Raspbery Pi4 + BMP180 sensor I see that data for 3 fields are uploading but not showing on chart at all:
Is refreshing every 5 seconds, reading correct data, but not showing on channel. Even I tryed to change API key, without success.
Does somebody has any ideea why?
Thank you

Thank you I can see the post.
Something like this it's in my mind:
I see a picture from the plant. It is live feed or just a picture?
Didn't found refference about how to embed live feed from pi camera in Thingspeek...
Do you have tips where to look?
Thank you again
Peter

If you have an IP camera that is pointed at your plant, you can have that image embedded on your ThingSpeak channel. It's not a streaming video, but it is a live image taken when the page is refreshed.
Here's an example:
1) Create a new MATLAB visualization and put this code in it:
imshow(webread('http://24.73.89.162/axis-cgi/jpg/image.cgi',weboptions('ContentType','image')),'border','tight');
2) Add this MATLAB visualization to your channel's view.
If you have an Android phone, you can get one of the many IP camera apps and try it out pretty easily.

Hi again
I mentioned that I want to use the Pi camera, not IP Camera. A refreshed image will be enough.
How can I embed the image captured to Thingspeak? And the refreshment of the measurements also?
Some ideea please? How tocreate a channel for the picture?
Do I need fixed IP address? I suppose not.
Thank you
Peter
