Hi I was wondering when you have a switch attached to a shelly dimmer 2 and you turn it on/off does it make a relay clicking noise?

And the shelly dimmer 2 can connect to two lighting circuits? and you can have two way switches for both of these circuits connected to the shelly dimmer?

Whats the minimum brightness dimmed to like? I know this is subjective to the no of leds/the load etc, but as a general rule can it dim to quite a low brightness in contrast to other smart dimmers?

Will matter come to the shelly dimmer 2?
