[mc4wrk]

System stop working after HA updates. All sensors are gone. Retryed to reinstall

Solax Modbus version 2024.11.2

HA

Removed old Hub and recreate a new one does not work any more.

Any advice will be very welcomed.

I have exactly the same Solax equipment and HA configuration and the same problem. I too have removed and re-installed the Solax Modbus integration a few times. The Solax Modbus integration will no longer install and it gets stuck saying "initializing".

Have you tried unplugging the PocletWiFi?
Also check if there is a newer firmware version for the PocketWiFi.

Yes unplugging seems to have resolved this. Thanks
