The switches reset into a neutral position, so you can’t tell if they’re on or off except for the LED.

The dimmers don’t make a noticeable sound but the switches make an slight audible click when turning on or off.

Worth noting mine are a few years old and they may have changed some things.

Are you looking for scene support (double, triple, etc click events) or just being able to remotely control the light?

Worth noting several brands have cheaper “add-on” switches to use in 3-way scenarios. You would only need one smart switch and add-ons for the remaining switches.

I personally have a bunch of Enbrighten dimmers/switches and add-ons that work like dumb switches when disconnected from the hub. I too was concerned with the WAF (wife approval factor).
