We’ve done this with Home Assistant (on a raspberry pi), and Zwave / ZigBee. Its been working great for years. Also allows for really customizable alerts for different things - and has been super stable.

Not very difficult to setup either - the interface is pretty polished these days!

I’d be curious how well this approach translates to multi-lingual keyboard layouts. For english users, perhaps theres another benefit to non-QWERTY layouts (e.g. Colemak or Dvorak) after all? … and two factor authentication should remain helpful I presume. Especially physical key methods with no audible characters typed (e.g. Yubikey, Titan, etc.)
