Help : Computed attribute for Speed

Hello Anton,

Can you please help me to set computed attribute for speed ?

I want to set if there is some time difference between fixTime and serverTime (No new position found by device) then the speed should be zero.

Is it possible ?

if not then I want to show speed is zero while device is not moving, currently it is showing last known speed for all the time if device is not in motion.

for better understanding of a question

You can't change speed value using computed attributes.

Ok, thanks

I will manage it from myside.
