I figured it out:

Created a dummy switch and set time 30 before sunset to turn switch on, at sunrise (before sunrise 0 minutes) it turns off.

This dummy switch now controls the lights.

Thanks for setting me on the right track

I don't want to invest in learning the LUA scripting language if it's not necessary.

This is basically the only thing I cannot figure out with purely using blockly.

Can you explain how to use a timer?

Hello,

Not sure were to place this question.

Ik want to turn the lights in 30 minutes before sunset. (At sunset it is to late). How can I accomplish this with blockly? Currently I'm doing fine with blockly and don't want to invest in LUA.

Are there any tricks to accomplish this?

Regards,
Jeroen
