Had to revert to 3.1

The same here....

[wlcrs]

Your installation has the wrong version of pyModbus (a depenency that this integration uses to make the connection) installed. This is due to another integration being installed/upgraded after installing this integration, which overrides the pyModbus version and causes a conflict.

I've already released a beta version which has upgraded pyModbus to the latest version. Please also upgrade to HA 2024.3.3. If the problem persists: please generate a diagnostics file and do proper debug logging for a while to allow me to diagnose the issue.

You can expect this issue to arise every so often when the pyModbus versions get out of sync again and incompatibilities surface. Also known as: the Python dependency hell

[ruteclrp]

Updated to HA Core 2024.3.3 and that had no effect on- as expected. Earlier today updated HA Core to 2024.3.2 which Bumped pymodbus to v3.6.6 Upon restart after this pymodbus update, Huawei Solar cannot anymore be loaded. It also means that it is not possible to download a diagnostics file.

[wlcrs]

Have you installed the latest beta version of this integration ?

[Eeleco]

I've had the same problem, but after instelling the beta everything looks okay again.

[madsdyd]

I have the same issue, I believe. On 24.3.3 and everything seems to be latest version.

How do I update to the beta version? Is it something I need to do in HACS or? No updates pop up in HA. I have never tried a beta version before.

Thanks

Okay so open HACS, go to Huawei Solar, go here;

My installation is in Dutch but I guess it will translate to "download again" or something.

After that just enable seeing beta versions and select the beta version (spoiler; it has a 'b' in it)

[duayfabi]

Same issue for me. Updated to the beta version and all fine now. Thx for the responsiveness.

[madsdyd]

Thank you veru much @Eeleco

It seems my HACS is UK, so I replicated the process for others that may be as HACS challenged as I, and has a harder time understanding Dutch (I am Danish, so Dutch is almost readable).

Open HACS, and find the Huawei Solar package:

Click, it, note the version (just for verification) and click the dot menu:

Click "Redownload":

Enable beta versions, select the new betaversion from the list, and download it:

Now restart Home Assistant.

I can confirm that this fixed my problem.

Thanks again, @Eeleco! And thank you, @wlcrs for creating and maintaing this amazing integration, and doing a fix for this issue so quickly! Amazing work!

[ablyes]

I can confirm. The 1.3.4b1 versions is working fine with HA Core 2024.3.3. Thank you for your high reactivity regarding this problem.

[ruteclrp]

Can confirm the new beta version makes the issue go away. Thanks for prompt attention.

Closed.

[artibea]

Hi. I can also confirm that with beta version 1.3.4b1 works fine.

[tfriberg]

Thank you! 1.3.4b1 did the trick for me. I no longer have to restart the service every morning.

[Misiu]

Thank you! Works great.
