Query recent activity

Configuration
1

Hello,
I’m trying to create an automation (in node red) that will turn on an extractor based on the time the room was occupied.

I can trigger an automation when a light is turned off.
At this point I want to know how long the light was on for.

This is to set the ventilator if it is needed.

Visit duration:
< 5 minutes - do nothing

5 & < 10 minutes - ventilator for 5 minutes
10 minutes - ventilator for 45 minutes

How can i query the recent history of device ?
or
How do I define a trigger that matches turn off after 5 minutes of on?

Steve
