SMA Integration from HACS, Inverter have to be re-loaded manually

Hello,

I have 2 SMA inverters, connected via SMA Device Plus in the Home Assistant. This worked well for a while. The current situation is that I have to reload the inverters every day manually
in the integration so that the values are recognized.

I have tested the following

  1. Delete inverters in the integration, no success

  2. Delete integration, reinstall everything. Success, runs for a few weeks, then the error described above occurs again.

What could this be?

Thanks for your help

Greetings
