Re: HA Holy Grail #1: Occupancy Detection

["Frank Mc Alinden" <frankmc@xxxxxxxxxxxxxxxx>]

Hi Andy

I use my standard alarm pirs to trigger  my cbus lighting via relays when
required....In the loungeroom i have a small sensitive pir connected to my
probe system via a black box which has a pic controller....If any movement
detected it triggers/retriggers a 5 minute timer ...Homevision polls the
pir
probe every 5 minutes and decrements a counter if the probe is off ...so
after 15 minutes if no movement detected it turns the lounge lights off...I
also added an ir receiver to the black box so if ir was received it would
also retrigger the 5 minute timer.....works quite well......
