Hi, I have a number of switches for lamps that I want to turn on, let’s say 30 min before sunset and turn off 30 min after sunset. I can create cards in the flows relating to sun rising in X minutes and/or setting in X minutes… Is it as simple that I can insert a negative number like -30 in I want the switch to turn off 30 min AFTER the sun sets or AFTER it has risen? Or another way ? Or not at all? ---

Lately I have been having issues too using date/time sunset feature. What I am confused on is if I create a simple basic flow, it will allow a negative number for 15 minutes after sunset. But if I put the flow into an advanced flow, it will not accept a negative number. Any ideas? I’m sure I am missing something so simple but it has me perplexed right now. ![Screenshot 2025-01-20 at 6.05.41 PM](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/2/d/2d878b5f56ce244ac5339a4407e8cee81b9648bc.jpeg) ![Screenshot 2025-01-20 at 6.06.33 PM](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/5/c/5c22da99e665cad5a3ee1a0a64ad0d6d0703115e.png) ---

The Sun Events app has way more options ---

I can enter negative numbers. Try a different browser? Or use a variable with a negative number. ---

Negative numbers in the Date & Time card is became a bug says Athom. Because it gives problems in other fields. Now I use the Zonnestanden app. ---

I have emailed them but know they are swamped and I was thinking this was a bug in system Date & Time cards but wanted to make sure. Stare at flows and home setup long enough and I swear 2 plus 2 is 5. Thanks ---

yeah looks like have to add another app LOL and change flows but that app looks spicy with options. But seem to be 180 from date/time meaning where put neg number in sun events have to us positive and vice versa. Confusing…but looks to be more robust.
