3 Function Outdoor Switch (Twilight, Timer, PIR Sensor)

[dblackeby]

I'm trying to find a switch for some external lights. I want them to come on automatically at dusk, stay on until a user specified time e.g. 10pm, at which point it switches to a PIR mode.

I'm sure I found one a few weeks back, but unfortunately forgot to bookmark the page, the closest I can find now is this:-

But that doesnt allow you to alter or specify the time that it switches to PIR mode.

Any suggestions?

Use a standard PIR and a separate timer. The lights are always under PIR control - unless you turn off the main switch off course. You connect the output of the timer in parallel with the output of the PIR and voila!

If you read this thread

you'll see that some PIRs misbehave when you feed power to their switched outputs. You'll need to check this when you choose yours.

Edit: Oops! I've just spotted something. You want your lights to come on at dusk rather than at a preset time. I'll have to think about that one. Time I wasn't here.
