Same problem with me. I updated and after the restart I lost all the sensors. I deleted the integration and added it again but nothing happens, it connects to the inverter but no longer displays any sensors.

[wlcrs]

Another pymodbus version is installed than what the integration supports. This happens when two or more integrations use that same dependency, but require different versions. v1.3.4b1 requires pyModbus v3.6.6

You will need to make sure that all modbus-dependent integrations support the same pymodbus version. Welcome in this special place of hell called the "Python dependency hell".

[RonnyStraetling]

Any idea how to fix this? How can I check the versions in use? Is there a way making sure pymodbus is updated to 3.6.6?

Hi, I think I have the same problem. This morning all worked well but than i lost all sensors. "Einrichtung fehlgeschlagen". I updated to the actual beta version but it didn't help. Is there a solution?

[sLesage]

Same here, I only get errors since a few days again... Seems to be happening every time there was an update to something I believe. I'll try to do the remove / reinstall dance to see if that helps fix the problem again.

I have the same problem. Have tried to remove and reinstall, going all the way to removing it totally (via HACS) and doing a fresh download. It now gets stuck on "Please wait, starting configuration wizard for Huawei Solar" which eventually times out with a "config flow" error. The version is the latest alpha.

+1 same here

Same problem here …

[themaninspain]

I finally solved it by deleting the integration, removing it from HACS and reinstalling (v1.3.3) from scratch. The integration now works with no problems.

Just updated to HA Core 2024.5.0 and the problem is back! Now recovering to a backup of 2024.4.4 (which was working). After reverting to 2024.4.4 the integration no longer loads, am trying to reinstall but I have a repeat of the config wizard problems and what I did before no longer works. I get this error message when configuring: "Config flow could not be loaded: 500 Internal Server Error Server got itself in trouble" After 24 hours of deleting, reinstalling, restarting and rebooting I finally go it to work again. Now I don't want to even try to upgrade HA Core to 2024.5.0

[Harald1387]

Did someone find a solution for that problem? I have installed all HA updates since the problem appeared. The behavior is still the same. The integration works for some hours and than the error appears. After some hours without doing anything it works again and than the error comes back. But I really have no idea why. Some weeks ago all worked fine for month. Nothing changed. The fusion solar app is working.

Hi! I think that I somehow fixed that problem. I’d just simply connected my inverter via wired connection, using Waveshare RS485 to ETH(B) POE Modbus Gateway.
The integration has been working perfectly for almost two months. Thera are no errors or disconnections.

My current versions:

Home Assistant

Core 2024.5.5 Supervisor 2024.05.1 Operating System 12.3 Frontend 20240501.1

Huawei solar : 1.3.4b1

I did not get the integration to work anymore. As I found it not very reliable and it stopped working several times over time, I switched to the native modbus integration via Modbus proxy. Modbus proxy is running on an old raspberry connected to the short ranged Wifi of the inverter and via cable to the home network.

configuration.yml huawei-sun-2000.yaml

[wlcrs]

v1.4.0 is out

[themaninspain]

And I still have the same problem. Every time there is an update to HA Core or Supervisor the integration does not load. No error messages appear and the only solution is to delete the integration and it's config and remove it from HACS. Reboot and and redownload and install from scratch - the whole process takes about an hour as I if I don't restart HACS after every step it fails to install.

@wlcrs Having the same issue with v1.4.1 and Core 2024.6.4

homeassistant  | 2024-07-02 21:39:37.290 ERROR (MainThread) [homeassistant.config_entries] Error occurred loading flow for integration huawei_solar: No module named 'huawei_solar'

I'm using HA in a docker container, also had to add the mount ./local:/.local because it tries to write some stuff there, maybe it's a good idea to mention this somewhere, or to write everything into /config as the docs currently indicates.

[brusch]

Uninstall / installed fixed it. Works now. Sorry 😊

[themaninspain]

I just wanted to say that I've now update to HA Core 2204.7.2 with no problems!
