driven the last 5 Minutes

[inReinbek]

I want to crate a flow that's sending a SMS to a caller while I'm on the road.
Up to this I want to send the SMS only while I was driving the last 5 Minutes (average speed higher than 10km/h for the last 5 minutes).

This flow should be read every 10 to 15 seconds the speed-variable from GPS (always on while I'm driving 'cause I've power supply in my car).

So I tried to set up the speed parameter as a variable set in relation to time.
Reading speed is no problem, reading time also is no problem.

My problem starts by setting speed and time in a variable to calculate a SMS-condition.
Is anyone able to help me ?

This script/flow will store current time(date) and speed globally so other flows can access them of you could trigger the sms from this flow.

Thank you, that's my first step, too. Now I've to store those variables every 10 seconds to calculate my average speed for the last 5 minutes ... do you have any ideas to store 30 variables periodicly and calculate "sum of 30vars divided by 30"?

I try to record the variable "location_speed" for about 30 times in a List.


My script is
--------script ---------------------
addElement(speli, location_speed+"\\n");
div = length (speli);
for (i in [0 to div])
{single = getElement (speli,i);
sumspeed = sumspeed+single
}
avspeed = sumspeed/div;
---------------------------------------

Checking the used variables on the screen always results a "null".
Where at hell is my mistake ?
