Huawei inverter integration no installer connection

Hello all,

I have this integration running fine for my Huawei Solar inverter GitHub - wlcrs/huawei_solar: Home Assistant integration for Huawei Solar inverters via Modbus · GitHub

All is great and I can get info and everything. There is one problem. To be able to login as the installer with the fusionsolar app i have to disable the integration. That is fine because I understand only one active connection is possible.

BUT, I don't know when it started, if I disable the integration, even then restart HA to make sure, no matter how long I wait I cannot login to the inverter from the app.

The only way possible to connect is to disconect the inverter, switch it off and then turn it back on all while keeping the integration disabled.

Has any of you experienced this? Is there a solution for it?
