Me too. I have a brass plate between the knocker and the bell that says
"PLEASE USE THE BELL". They still don't. The bell can be heard all over
the house, even at the end of the garden. The knocker can't.

I'm still pondering adding a circuit to the knocker so that, if used, a
loud voice intones: "PLEASE USE THE BELL!!".

I like that idea!

So do I. But rationally, if you are going to fit a switch to the knocker why
not make it operate the bell? An additional voice announcement is optional:
"I told you to use the bell!".
