Hey,

i would like do get a true/fals 1/0 on dawn/dusk depending on the gps location.

i inject to the input:  
S1 : msg.payload : string[22]

"geo\_override 53.22 6.6"

but the off time is always wrong with the injected coordinates. With fixed coordinates its correct.

i have no idea what's wrong

best Lars

I noticed here

[https://tech.scargill.net/big-timer/](https://tech.scargill.net/big-timer/)

that in the comments the author says this

so perhaps you need 06.06 for the longitude value or whatever the correct value is in the format of 2 digits on both sides of the decimal.

### NOTES

Why did I chose Northern Greenland as an example?  
Why did I do a future date example?

Not many solar nodes/modules do a good job of figuring out the prev/next solar events - and it gets worse when the location doesnt have that event until some months later.

Look closely at the screenshot - see how Northern Greenland's next Dawn event is not until 23rd Sept.

urm, ok 🤣

I was just showing you how you can get dawn/dusk/you-name-it dynamically using cron-plus & you will get more features and more importantly, it works! import the flow demo & enter `53.22 6.6` to see for yourself (or not! 🙂 )
