3-way double in-wall switch with dimmer

I was looking into the Xiaomi “stuff” to start my smart home project when I realise I have a situation were their “stuff” might not support, and I’d like to prevent (as much as possible) having to buy multiple “protocols” & gateways.

In the hallway/staircase we have a 3-way double in-wall switches, which I would like to also add a dimmer to.

Has anyone achieved a similar setup with Xiaomi “stuff”?
Are there any alternatives out there?
