SHELLY problem - how to connect a remote Shelly EM - Native integration

Hi please can someone explain me how to connect a second Shelly EM?
I have one in my home, and the second in another home, connected to its wifi

the first one was easily auto-discovered by HomeAssistant (1 device, 18 entities), but the second?
It is connected to shellycloud, and I can control it throw it’s native application, but when I try to add it in HA the system ask me “HOST”
How to configure it? I remember, with the other integration it need an API, but here?
thank in advance who will help me
