Doorbell to Text, is there such a thing?

Technological ignoramus that I am, I'm not really sure what I am asking, so please be patient...

I can't have the doorbell ring, as the sound can trigger a seizure in Robin Goodfellow.

For years I've had a note on the door to please text rather than ring or knock, another note actually blocking the doorbell - but there are always people who cannot /will not text and ring anyway.

For a while I had disconnected the doorbell, but that is less than satisfactory, as the person at the door simply keeps at it, getting frustrated.

So... I vaguely remember hearing about some kind of doorbell that sends you a text rather than rings. Do any of you know what product this is, and where I could find one in Switzerland? And most importantly, is there really no sound?

Many thanks!

I don’t know about the text thing but I did find this

I guess some those should work:

Push notification doorbells by digitech

At least those that are part of “smart home system” usually work also on a smart phone. You will see also the notorious Amazon Ring system, the latest “big brother”.

Or you go a low-tech and you connect a light bulb (instead of the bell) to the doorbell.

Get a new dog ?

Can you change the doorbell sound? Something melodious?
