Use additional input for speed

Hi Anton,

I have a Teltonika device that communicates speed (GPS Speed) but I would like to use an additional input, io81, for speed. I tried below which then create a second Speed value in state panel. I only want one speed value.

Attribute: Speed
Expression: io81? io81:null
Type: String

and also tried

Attribute: Speed
Expression: io81? io81:null
Type: Number

I searched forum but didn't get the answer I was looking for

Unfortunately it's not possible to override speed because it's not an attribute. It's a part of the base position model.

Thanks for the quick response.
