Qubino Flush Motor Controller not showing up in Google Home devices

I have my ST account linked to Google Home. While most of my devices show up in Google Home, some, including this controller, do not. Is this a limitation of Google Home, or some sort of broken link between accounts?

Thanks!

did you find any solution to your problem?

No! surprised myself.
I have found that Google treats shutters as “security” systems and defaults to not allowing voice control, but this seems like a different issue. And Google home seems to actually support blinds now, just not these ones. Maybe something with the custom handler involved with using this with qubino/ST?
