I have recently installed an NCD MegaModem paired with an NCD Temperature sensor for our lab freezers (-80c). I have set the gateway for MQTT transmissions. I can see that my MQTT gateway is transmitting data to since I am getting the following output:


My question is:

How can I select/choose to show only temperature_celsius on the graph? Right now I am not getting anything on the graphs.
Field1 name is temperature_celsius.

Thanks a lot!

That looks like a JSON block that would work in HTTP POST. See the MQTT documentation for the correct MQTT format.

FYI, MATLAB answers is the preferred location for ThingSpeak Community support.
