After upgrade to new version - unable to add invterter - unknown error

[perjmolsen]

Describe the bug

Hi I have upgraded to the newest version of SolarX modbus, now I am unable to add my invterter.

When I try to add it, I get "unknown error," I am adding the inverter withh the same information as earlier.

mic3000tl-xe /dev/ttyUSB0 9600

I have removed the old invterter - rebooted HA og redownloaded the newest add on - still the same issue

Please help

some here - other inverter brand (tigo/qcells with solar plugin) but some method used ... usb to serial

[perjmolsen]

How did you solve it?

[wuschi1983]

Same problem here

[Zvolli]

Same issue here, all unknown entity state. Followed instructions with warnings but problem still occurs. Downgrade to main does not take any effect. Removing SolaX from HACS and re install it does not work either.

Same problem here with Growatt SPH6000 .

Workaround would be - downgrading via zip download of version 2024.05.07

https://github.com/wills106/homeassistant-solax-modbus/tree/2024.05.7

[mfcltd]

Same problem too.

[rhlavienka]

the same here Solax G4

I've tested downgrading to this version and it does get round the issue.

@perjmolsen

You can get more detailed error logs following: https://homeassistant-solax-modbus.readthedocs.io/en/latest/faq/#detailed-error-log

@Zvolli

Do you get "unknown error occurred" when adding your Inverter, or just your entities have gone to unknown since updating to 2024.08.x?

For everyone else who's saying "same here" can you clarify what the actual issue is.

Either "unknown error occurred" like @perjmolsen Or all entities are showing "unknown"

[granthgh]

My original issue was that after upgrading to 2024.8.6 some of the entities became unknown. I then deleted the inverter and tried re-adding it, but when I got to the box with the COM port / data rate I got the unknown error when actioning it. Since then I've downgraded to 2024.05.07 I was able to add the inverter and the entities are now working. There are no errors in the logs.

[Zvolli]

@@.***> After updating to 2024.08.x all entities went to unknown state. If i delete inverter and solax, reinstall I can add my inverter with success but of course with unknown state for all entities.

@wills106 I'm sorry, I thought all of us have the same issue. I removed inverter from integration and after upgrade to 2024.8.7 is not possible add it back. I get "unknown error occurred" when adding Inverter.

[Zvolli]

Sure but downgrading in docker container is for me a unknown territory 🙂

Same problem too.

@wills106 - When re-adding the inverter after upgrading, the unknown error occurs.

[HaareistNase]

Edit: other Problem I can add Growatt SPH4000 and MIC3000 But all of the Sensors on MIC reads "unknown".

Downgrade to 05.07 solves the Problem.

Hi,

can you please briefly explain how to perform the downgrade?

[toszym]

I can confirm, downgrading to version 2024.05.07 works. Steps to follow: remove current version from HACS and then follow manual installation steps ( download tar.gz or zip archive, upload to homeassistant, unzip and move solax_modbus folder to /homeassistant/custom_components/)

[Zvolli]

I can also confirm 2024.05.7 works but by doing this maneuver it does not appear in the HACS section. In my case it's in Synology docker container.

I waited 2 days if by chance updating the entire HA doesn't solve the problem. No it didn't. So I also downgraded.

Using the File Editor, I deleted the content of the folder /custom_components/solax_modbus and replaced it with the content from version 2024.5.7. I can't delete folder or multiple files at once in the File Editor. It is necessary individually, but there is not much of it.

See Manual installation https://homeassistant-solax-modbus.readthedocs.io/en/latest/installation/

[shaarkys]

Same here, trying to add Solax X3 G4 after removal due to the unknown entities after 2024.08.8 upgrade and duplicated inverters (even I do have only one) and can't get over this :

Time to manual downgrade and re-adding back inverter.

I'm on HA Core 2024.8.0, Frontend 20240806.1

update actually might be user error, I used wrong port number - confirmed, it was user error. Still I would expect some time out or something like that but had to restart HA to recover....

[ruimmsimoes]

I have a SolaX inverter and I’m having the same issue. I upgraded to version 2024.08.08. When adding the inverter after the upgrade I’m also getting the same error message. In the logs I am seeing an error message that is the same as the one reported in this 2 issues:

988 - Solax X3 Hybrid Raspberry RS485 USB -> Unknown error occurred

976 - 'SolaX' - 'Gen3' crash on add integration "KeyError: 'support-battery'"

[ralfna]

Same issue with Qcells/Solax, in addition to downgrade I have to reset the WiFi dongle to get the integration back to work.

[wills106]

Temporary workaround is explained https://github.com/wills106/homeassistant-solax-modbus/issues/996#issuecomment-2284023411

[martinpichlo]

Workaround ist not working for me. Trying to add the integration with TCP/IP didn't come back but and stays in "initialization". Changing settings in that state results in an integration without service and devices, after reboot :-(

[martinpichlo]

I can confirm, downgrading to version 2024.05.07 works. Steps to follow: remove current version from HACS and then follow manual installation steps ( download tar.gz or zip archive, upload to homeassistant, unzip and move solax_modbus folder to /homeassistant/custom_components/)

Is the downgrading of the integration also working on HA 2024.8.1? I don't get it working. I'm able to select the integration. But instead of "unknown error" I got a spinning waiting icon all the time.

@wills106 : How could we all support, find the problem?

[wills106]

I have released 2024.08.11 it may fix this error, but no error logs in this issue thread so can't check.

[granthgh]

I have released 2024.08.11 it may fix this error, but no error logs in this issue thread so can't check.

Still got the same unknown error has occurred, with 2924.08.11. Attached the only entries in the logs, but unsure whether these are related.

[wills106]

@perjmolsen I don't know if 2024.08.12 will help with your issue, but it should resolve @granthgh issue. Where it can't read "Inverter Module"

[wills106]

Has this been resolved so I can close this issue down?

[granthgh]

Issue still exists, but workaround, setting up as tcp and then changing to serial, gets round the issue.

[wills106]

I didn't introduce the serial support, are you able to try and fix the issue? I don't use or own any RS485 equipment, so going to be difficult to fix from my end.

[granthgh]

The issue is that there's no errors recorded, so it needs someone with an offline system, as I need mine up and running to manage my inverter. I presume there have been significant changes since the working 2024.7, so difficult to identify the changes to the code that broke it. As there's a workaround then I think it can be put on the back burner and If you want I'm happy to look at the code to see if I can spot an issue.

[shavermcspud]

I had the same issues, I can confirm, re-configuring to TCP then saving, go back in and edit back to com port and it works.

[wills106]

Just released 2024.09.3 which hopefully fixes this error.
