Switching outside lights at solar events doesn't work reliably, sometimes not at all

Flow looks fine. But the And-card looks a bit useless. Why you add it?

Instead of using the app voor logging; you could also try to add cards to put info in your timeline or send a notification. So you can check when it runs to make sure it is because of this flow.

Also you could check the timeline in your devices to see if it gets turned on by the flow or for some other reason.
