Hi I am new to IoT and have just set up a Cricket module which is transmitting "temp" and Battery data to Thingspeak and is showing a number of entries but they are not displaying any values

I have it working by using GET (which seems counter intuitive) and adding fields and not using payload. But like yourself perhaps I followed the article in PE but after several attempts thier route just did not work for me.

Can either of you share your channel ID if they are public? Then we can have a look at the data you are sending and see what is happening.

OK, I am new to Cricket too and also followed the PE June 2021 article instructions to a tee. Thingsspeak looks like it it getting data every minute but nothing shows on the charts.

I also entered the same information in the Payload entry for temp and battery for fields 1 and 2 as instructed in the PE article.

So I take it that this doesn't work and I need to try something else? I am not familiar with "Get."

Thank you for any information anyone can provide.

Thanks for the additional information. Is there a problem or did you get what you needed?

I was not the one with the problem Christopher. I had the same problem but solved it. The Cricket seems to be the problem in using its payload data sending method. I followed the Practical Electronics instructions to the letter and the result was the data seemed to arrive as the 'count' showed on ThingSpeak but no data was displayed graphically. So I suspect ThingSpeak was receiving an empty file.
