Hello,

I want to switch on the light for one minute using a PIR but only after sunset and before sunrise. How can I acconplish that?

It’s quite simple to do with a blockly.

- make a variable ‘nighttime’
- make a blockly
“if time is sunset” “set Nighttime =on” and “if time is sunrise” “set Nightime =off”
If Pir is on and Nighttime is on set light=on for 1 minute

That’s all.

If [Time > Sunset] or [Time < Sunrise] and [Light = Off] and [PIR = On]
Set [Light = On for [1] minutes.

I used a dummy switch instead of a variable as Treve wrote. This Dummy switch was switched by timer. But this is not necessary for what you want to accomplish now.

If [Time > Sunset] or [Time < Sunrise] and [Light = Off] and [PIR = On]

As far i know there are Time complications with calculations before 00:00 and after 00:00.
That’s the reason I made use of a variable.

[AllesVanZelf]

The complication you refer to is: If [Time > Sunset] and [Time < Sunrise]
That will never happen. That is why I used OR.
If [Time > Sunset] or [Time < Sunrise]
Then it is working.

If [Time > Sunset] or [Time < Sunrise] and [Light = Off] and [PIR = On]
Set [Light = On for [1] minutes.

Produce this solution every minute a ‘on’ signal?
