HI All I really hope this is a silly question and someone will point out what i am doing wrong ! I have tried with both the built in Date & Time function and after some research the Sun Events app but i cannot get the flow to work properly Below is my flow, i am just wanting the light to turn on 45 mins before sunset happens. No matter how i do this the light never turns on and i cannot figure out why. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/d/8dcd555a8512390452134fd345a82af21a664b4d.png) Thanks in advance!! ---

You need to insert **-45** in the Sun Events Flow card, not 45. ---

Put a timeline notification behind the trigger and the AND. Maybe it goes wrong on ‘Someone is at home’ ? ---

And, always add a notification card right after the trigger(s), to find out if the trigger actually fails, or other parts of your flow fail, or just don’t act as expected. ---

To test a faillure I put one behind each card in the flow. ---

Thanks Everyone using the -45 has fixed the issue! Really appreciate the guidance, and again sorry for the basic question 🙂 ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/2/327453440326a52621190cc459582d873a8243f0.png)
