HA, zigbee, LED dimmer and multi-way switch

Hardware
1

Hi,
I spent hours to learn about protocols, boxes and electricity.

I’m thinking about HA (Green+Skyconnect) in combination with 3 switches to set on/off/variation of light on LED dimmer.

What do you think about this schema ? Is it possible to command the LED lamp without HA and to use dimming from any command point ? And will it work with HA :slight_smile:

If this schema is valid, I’d like to replicate it for 3 other rooms and manage all in HA

Thanks for your help
