Switch a whole group based on sunset and sunrise

Hi forum.

I have created a group of Shelly devices.

My aim is to to switch that group On or Off based on sunset and sunrise.

Can anybody think of a clever way to do this?

Any suggestions to get me on track are welcome

Thanks.

Thank you SebMai. Excuse me for my late reply.

I have used this solution for some other scenes and it works well.

However, for the sake of simplicity, would it be possible to trigger the group itself at sunset/sunrise?

Ok. I will see if scripting is something for me. Does it mean that I have to go into mqtt?

I that case: what client and what server/broker would you recommend?

I have tried a few times to get myself started with mqtt but I run into issues like security and missing bits of windows.
