I have a channel in ThingSpeak. Field number 4: Temperature, with some data. But, when I try to read that data in Simulink, I only receive 0... What could be happening?

Hello Vinicio,
I just tried to read from your thingspeak channel and got the data. I ran the model in “Monitor & Tune” mode and could see the data. Please check the attachment.
To confirm the issue at your end please share the output of status port and the ‘Diagnostic viewer’

I´m trying with another blocks, and with this one, it is working. But, I need send this to run over a Raspberry Pi, and I can not use the ThingSpeak Input block. But, here is obviusly that the problem is in the Raspberry Pi ThingSpeakRead block...

On the other hand, if I use Raspberry Pi ThingSpeak Write block, it is sending all the time a 0. When manually I change that value with a 20, the system write a 20... But, the value of the constant in the left side is just like it doesn´t exists.
