Hello.

I want to make a flow that if the backdoor is open for About 10 minutes, the Nest thermostate turns down to 16 degrees.  
I have a sensor on the backdoor.  
Is there a counter that counts up instate of down?

So, in this case, what will be the difference between counting up or down?  
WHEN door opened THEN start a timer for 10 minutes.  
WHEN door closed THEN stop timer.  
WHEN timer is empty THEN turn down the thermostat.
