[SOLVED] Creating a Derived Variable in Ubidots STEM

Hi,

I am trying to create a derived variable with the following text:

-0.004886457tilt^2 + 0.868732344tilt - 16.46755357

It seems the STEM Unidots doesn’t have this function? Can I do this with a Synthetic Variable?

Thanks.

I worked it out

Hi there, I am glad to know that it worked, there should not be reason in the core to avoid your expression to be calculated rather than the computing time. Ubidots stem has some limitations for synthetic variables related with the special functions, you can reference additional information about this here.

All the best

Thanks very much jotathebest

I am having the same problem. I am using Unidots STEM and there is no option for a derived variable. Any workaround would be greatly appreciated.

Greetings, the derived variable was replaced by the synthetic variable concept. You can create synthetic variables just making click in the add button in your device detail view:
