RE: HA Holy Grail #1: Occupancy Detection

["Andy Laurence" <andy@xxxxxxxxxxxxxxxxxx>]

Interesting points.  Thinking about it, I don't have automated
curtains.  I wouldn't want the lights turning on and illuminating my naked
body to the street should I nip downstairs for something before getting
dressed.  Wouldn't have thought the neighbours would like it either!  It
will be useful for some rooms though, such as the dining room, kitchen,
hall, landing, bathroom, and bedrooms.  Not to mention cupboards (Node0).

Cheers,
Andy

It's also a good idea to walk around the areas you want to cover at
different times of day and be consciously thinking - do I want the lights
to come on now or not? I found that having them come on automagically can
be actually quite annoying sometimes - i.e. you hear a noise outside and
creep to another room to have a look; someone's asleep in the room. OK, not
the best examples but you get the point.

Sometimes it may be best to still have the conscious human interaction
controlling the lights - depending on local circumstances. My downstairs
cloakroom has the lights always turning on via the PIR - pretty good and I
haven't yet found an occasion when I don't want it to turn on. HOWEVER, I
constantly find myself wanting to turn it off after use manually (it's on a
10 minute timer). Quite frustrating actually as I have to leave the room,
wait 10 seconds for the last PIR activation to be registered and then press
the switch! OK - so better design might solve this but what I'm trying to
get at is the logic quickly becomes quite complex once you look at it
closely and start to take all the factors into account.
