dimming lights suggestion

[Gianni]

i had rewired all my switches to place my sonoff(with i will switch with Zwave ) and now i need to replace my ceiling.
My wife want dimming gu10 and 2 different circuits of bulbs.
So i pull 2 black wire to my celing and add a 2 gang switch.
But now .....
I still cannot dim this bulbs
Looking here but there is so much information that i don't know how to start.
Instead of 2 gang 2 wire's i think of put a 1 gang in it.
Then i buy a Ibox2 with GU10 rgbww leds
So i can control the bulbs on and off with the normal switch and i can program the ibox2 to have 2 or even more circuits?

is this correct or i'm i complete wrong?
Can i command the light with alaxa on my HA bridge?
Whats the different between the IBOX2 and the ibox V6?

Hope to get something clear up before i buy everything

to dim lights you need a dimmer, not a switch
