Re: Pir 2 way switching

["Alan Cockerton" <alancc@xxxxxxx>]

The only trouble with that is if the light is already switched on the PIR
will turn it off. Can you not just connect the PIR to operate in parallel
with the existing switches then if the light is off it will come on, if its
already on nothing will happen.
