Hi There all
How good is CoRE then?
So I have my 1st application for this amazing capability.
It intended to only activate the extractor when there is prolonged motion 
IF
MOTION_SENSOR remains ACTIVE for 30 secs
THEN
Turn EXTRACTOR SWITCH on
Wait 2 mins
Turn EXTRACTOR SWITCH off
So I have found a way to do this using a TRIGGER that STAYS ACTIVE but the minimum time is 1 minute.
Has anyone got a better suggestion?
