Hi, I need some advice: In our house we have mechanical doorbell which is operated via the top-switch of the lightswitch panel on the outside.

Inside we have the following mechanical chime:

What would be required to replace the mechanical doorbell with a Ring? Can I do this myself (I have no problem rewiring wallsockets / fixed lights) or would I need an electrician?

Any suggestions to installation of the doorbell? I thought that I would replace the 3-light-switch panel with a 2-light switch panel and use the space above it for the doorbell installation.
