1 Smart Life Account connected to 3 Home Assistants


I started with smart life some time ago and manage four locations on one account.
Three locations shall use home assistant.
I created an Tuya Cloud project and successfully linked it to my first location‘s home assistant. Worked fine.
After setting up my next home assistant using the same tuya credentials I had connectivity problems. Therefore I created a second project, linked it to smart life and used these credentials. Works fine.
Now at the third location I am running out of ideas. I can‘t connect my smart life account to a third cloud project.

Is there another approach without having to move one location to a new smart life account?
