I think it would be nice to change the text for hint number 2 in the English forum post for beginners Beginner's tips for shelly and the forum
and direct people straight to connection diagrams - overview (as an example link to the lexicon). Three reasons why I suggest this: It's a great resource for beginners, and in the English language, I think people would look for 'wiring diagrams'.
The last reason is that it may not be clear to people that their language settings may prevent them from finding the German or English posts, depending on the settings in their profile.
