Unable to import component: No module named 'pymodbus.client.sync' after upgrade to 2022.10.3 and/or OS 9.2

[Claudio1L]

recently I started to see error msgs after the reboot. Usually after one or two try the error disapper and working fine. Today I'm not able to make it works. Looks like a module is missing. Could be one of recent updates?

looks like python disappeared?

[Claudio1L]

reverted back to a snapshot with OS 9.0 and it worked.

It is something related to OS 9.2

[Claudio1L]

Same issue after reboot with 9.0 Also.

seems related to 3.0.0 pymodbus recently updated https://github.com/home-assistant/operating-system/issues/2188

seems related to 3.0.0 pymodbus recently updated

The component uses a pinned version of pymodbus, so the upgrade of pymodbus should not have effect.

I'm on HA Core 2022.10.3 and don't have this issue when restarting.

Any advice on how to proceed ?

Have same issue in two integrations using same component. The second one is:

Thanks Claudio

Maybe the problem is this: the solax integration doesn't use a pinned version of pymodbus, so this could probably install pymodbus 3.0, that is not compatible with my integration, and I think that is not compatible also with solax integration because 3.0 is a breaking change release.

Test this: uninstall both integrations and restart. then reinstall mine (ABB) and restart, check if it works. If it does, then the problem is the conflict on the pymodbus version requirement of the two integrations.

[Claudio1L]

Don't understand why but it was a conflict with the Bluetooth usb key I recently added. Removing the key and the bluetooth integration is working consistently fine. At the moment I can live without it. My apologise for the confusion

[Claudio1L]

after update to 2.1.0 issue appeared again on bot integration. I'm lost, I had to rollback to the previous snapshot. Before rolling back, I tried to remove everything form integration page and redownloading from hacs, ABB integration (2.1.0) was working fine, Solax integration refused to install for missing pymodbus.client.sync. I'll reopen the bug on Solax beacause it seems it have issue with pymodbus 3.0.0.

[alexdelprete]

You have to tell other devs to update their components to latest pymodbus 3.0. That's what I did.

[Claudio1L]

Confirmed. They just released a beta to address this issue and seems working fine. Thank you for the support
