Customp Temperature sensor values are wrong on dashboard


I just started with Cayenne so, maybe, I made a mistake.

I am testing on Arduino Uno with W5100 ethernet shield and using Web dashboard
I wished to upload the internal temperature of the Atmega 328 so I loaded the Cayenne Line Chart Widget Example, and modified only a line and added only a function.
I added this line
Cayenne.virtualWrite(VIRTUAL_PIN, GetTemp(), TEMPERATURE, CELSIUS);

GetTemp is the function that return a double.

I added a Serial.print to debug temperatures

The temperatures printed locally are around 28-30 C but in dashboard I see values between 80 and 85.
When I created the widget I specified to use Celsius but my suspect is that the Celsius values are still converted in Fahrenheit.

Its because what you see in dashboard is fahrenheit.

google says 28 celsius is 82 fahrenheit.

my suspect was confirmed, thanks!

How can I visualize Celsius? I used Celsius in the creation of Widget and if I check on Settings it is still Celsius.

one way could be to recalculate it:

(T(°F) - 32) × 5/9
