[QUOTE="Richard-the-Ninth, post: 522546, member: 23472"] As Sharpend says, it would be easier to leave the fan running 24/7 With that in mind you only need to turn the light on/off, a PIR would be no use as it would see the draught caused by the fan, what you need is a "Fridge switch" [URL='https://www.tlc-direct.co.uk/Products/FM142.html']Click here[/URL] Just like a fridge it only works when the door is open. If you really want the fan to stop AND the light turn on, you would need a change over switch [URL='https://cpc.farnell.com/honeywell/glcb-01a2b/limit-switch-roller-lever/dp/MC01798?st=limit%20switch']Click here[/URL] But its a lot of grief for no gain.
