Door open? thermostate down


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.

Haha you are right. Makes no difference :see_no_evil:
