Devices not showing

[Juanpermon]

After a long battle I have been able to install the integration. Now it shows one device (Shield) with one entity (diagnostic). I have three thermostats added onto Google Home App even with automations involving them. How could I make the integration to scan(?) for these thermostats? This integration is for this purpose, doesn`t it? Thank you.
