hi!
In place of TL;DR; 
Right now I am living not at home. My home with above 120 devices and cool HA now is occupied territory. 
I am living in my friend's apartment and from the boredom I'm building him a small HA here.
So, let me introduce a small node for "motion light" action.
This node can help you a simple automation with lights in your house / room.
Just drop on the flow motion-light node and configure behavior by profile
current version support only three parameters:
"lux": 1,
"brightness": 50,
"timeout": 10
lux - min lux for lighting (opt)
brightness - if you use dimmer - that value for you =)
timeout - how many times the node should be waiting another "on" motion before sending "off" command
You can pass lux value by external entity and mark this event via motion-light-event node
Also, you can prevent "on" by mark motion-light-event as "exclude" event.
For example, you wouldn't be lighting "night lamp" if basic / main lighting already on.
See example for more details.
