Xiaomi HUB 2 - Alarm speaker? siren ?

Hello, i recently purchased a hub 2 and 5 windows/door mi sensor 2,

everything ok i receive notifications on my phone when a door is opened.

the problem is that the previous gateway hub was having a speaker inside and it was producing the alarm and the Hub 2 NOT!

i tried to contact with service on Greece & global with mail and no one knows its product.

is any chance to connect a smart speaker xiaomi to do the SCENE when a doors opens to play an alarm sound?

can i connect anything else? siren something?

any aftermarket speaker?

any other mod firmware on hub?
