Shelly App, but no login available?

I installed the SHELLY APP, and I expected that in the app (as with many similar apps) you log in to the cloud of the relevant brand, and that your devices will then become visible in Homey.
I was hoping to add a Shelly smart plug in Homey (but it’s in my office in another building, not in the same LAN as the Homey).

But in the Shelly App on the Homey I can only disable CoAP and adjust the polling frequency. You cannot log in to your Shelly Account, after which all Shelly devices in your account will be visible in Homey. Is there a workaround for what I want?

Greetings,
Richard

The app on Homey Pro only supports local connections. You can use Homey Cloud is you want to use it over cloud connection.
