Openhab google home assitant

is there a way to add Two openhab cloud instances to one google home account?

It’ seems in google home app on IPhone i can add only one Openhab device with one mycloud login/password?
Is there a workarround for this ?

There is no way to do it through the Google Home App so Google itself doesn’t support that. It’s the same in the Android app. Each linked service only supports one login.
