If you simply want to block certain sites, why not use Pihole?

I had used Hibiscus in the past. The source code can be found here: https://github.com/willuhn/hibiscus

yes, you should definitely check regularly if the Automation does what you want, there are some stumbling blocks e.g. Difference of presence detection and persons. I spent about a month until I’ve understand enough so that it does what I want :)

That’s exactly how I do it too, I think otherwise this automation would be too complex to handle (it is already very complex) 😊
