Scene not working as wanted

I got a scene with 2 firabo motion sensors as triggers. Once tripped the lights go on.
As seconed scene checks if the 2 motion sensors see motion if not for 15 minutes the lights go off.
Somehow the lights still turn off even whem there ar 2 or more people in the kitchen where the senors are.

Need a better scene or lua i think
who can help me.

You have two options
You can set the reset rate on the Two Fibaro to be 10-15 minutes then use conditional LUA code in your scene to check that both sensors are untripped using examples from here http://forum.micasaverde.com/index.php/topic,18679.0.html

You can use PLEG plug in, which has lots of examples how to create occupancy lighting.

I tried PLEG but the latest version made it difficult to understand and I didn’t find a new manual yet online
Let’s try the reset timer and conditional setting first
Many thanks
