My setup with SUN2000-8KTL-M1 (Firmware Version V100R001C00SPC168) with SDongle via LAN works fine.

I had connection problems after Update SDongle to Firmware Version V200R022C10SPC200.
After Downgrade to V200R022C10SPC126 no issues with connection.

Maybe you have some firmware issues too?

Same problem with 1.4.1 and beta2 version.

For testing I reinstalled the integratration and update to latest 1.5.x.b2 and tried to reinstall. Reinstall integrated does not find and install Huawei integration.

Noticed: "Users that use the native modbus-integration alongside this integration should not upgrade to Home Assistant 2025.1, as it contains an upgrade to an incompatible version 3.7.4 of the pyModbus library. Significant work has already been done to upgrade this integration to support v3.8.0 of this library. We expect this to release alongside Home Assistant 2025.2, which is expected to also upgrade to that latest pyModbus version. This will solve the compatibility issue."

Well, that makes sense why my integration brokes. I will wait.

The Firmware was always the same version

[cybermailer84]

In my case i do not have changed the firmware of any device (EMMA, MAP0). With old Home Assistant 2024.12 no problem. I went back to old version everything is fine. Strange was with installed integration i was able to update to new HA version and some value i have seen, but not all. therefore i deinstalled. But now a new installation with new HA Version is not possible.

Jumping to 1.5 rc3 fixes my problem.

[cybermailer84]

in my case probably not because of using modbus tcp also for nibe heatpump

After the update to.1.5.1 the configuration Dialog work again. After restart the same Problem gain
