I can confirm after last update:

Setup failed for modbus: Unable to import component: cannot import name 'Defaults' from 'pymodbus.constants' (/usr/local/lib/python3.11/site-packages/pymodbus/constants.py)

Victron is working, but my modbus in confguration.yaml is not working anymore after update to 0.1.3

After reverting back to 0.1.2 my modbus config is working again (aswell as the victron*)
*) sometimes this error (0.1.2):
Setup failed for custom integration victron: Unable to import component: cannot import name 'make_byte_string' from 'pymodbus.utilities' (/usr/local/lib/python3.11/site-packages/pymodbus/utilities.py)

After rebooting HASS victron (0.1.2) is working again.

Same here :(
After removing "modbus: !include modbus.yaml" in configuration.yaml the error message disappeared and Victron integration is working again.
Unfortunately I really need my modbus.yaml.

Unfortunately +1 on the error:

Setup failed for modbus: Unable to import component: cannot import name 'Defaults' from 'pymodbus.constants' (/usr/local/lib/python3.11/site-packages/pymodbus/constants.py)

same here

uninstalled it with hacs but problem is still there.
all my modbus devices are gone.

please fix it

[wasn-eu]

my whole system relies on the normal modbus for reading about 20 energy meter
We need a quick fix

[wasn-eu]

i have forked your repository and changed the pymodbus version to 3.1.1 in manifest.json

after insalling that package with hacs i can use the normal modebus system and victron

Sorry that i'm unable to quickly patch issues with this integration at the moment.
In case of issues with a new release you can also select redownload integration in hacs and download an older version again until a fix comes out

[smout74]

After upgrading to HASS 2023.8.4 and re-installing this version 0.1.3, for me the issue seems to be solved. Both the Victron and normal modbus (Energy kWh meters Hiking via tcp and standard HASS modbus) seem to be working and updating as normal.

It's running like this for 50+ hours, no complaints anymore.

[sfstar]

Please test the beta v0.1.4 release of this interation (this is a copy paste reply which isn't customized for each issue v.0.1.4 is attempting to adres).
Make sure that (in cae this applies to you) the core modbus integration is also fully enabled after bumping to version 0.1.4 and let me know if the issue persists.

Hi , beta v0.1.4 broke the entire intergration in that it couldnt start the intergration , Regards

Here too :(
After installing the Beta and re-enabling "modbus: !include modbus.yaml"
The system wont restart and gives an error :(

[peregrines2]

(after installing the Beta I was able to restart though)

[sfstar]

Later releases adressed the incompatibility between the HA core modbus integrations pymodbus version being used and this integrations pymodbus usage.
Therefore, closing issue for now.
Please re-open if the issue persists.
