Config flow could not be loaded error message when trying to add integration

[saberone]

I just installed the saj-modbus plugin. But when I try to add a SAJ Inverter Modbus integration I get the following error:

Config flow could not be loaded: {"message":"Invalid handler specified"}

When I check in the log file I see the following to error logs:

Error occurred loading flow for integration saj_modbus: Exception importing custom_components.saj_modbus.config_flow

I'm running Home Assistant 2023.6.3 and HACS Integration version 1.32.1 and Frontend version: 20220906112053.

Any help is appreciated.

I cannot reproduce this issue with my own install. Can you tell me which Home Assistant versions and installation type you are running, and on what kind of hardware?

[riconekkers]

Home Assistant 2023.6.3 Supervisor 2023.06.4 Operating System 10.3 Frontend-versie: 20230608.0 - latest

I'm running a virtualbox image on a server with a AMD Ryzen 5 3600 6-Core Processor.

i'm testing now on a clean install if i can reproduce the issue

looks like solaredge modbus (https://github.com/binsentsu/home-assistant-solaredge-modbus) in combination with this intergration gives this issue. If i remove the solaredge intergration and reboot HA the problem is gone. install solaredge intergration and the problem is back.

Hmm. I also have a solaredge modbus hacs module installed. So that combination triggers this issue.

Can you check if this problem is resolved by using version v1.8.0 ? There were some changes to support newer pymodbus versions: https://github.com/wimb0/home-assistant-saj-modbus/releases/tag/v1.8.0

[saberone]

I installed version 1.8.0. And the installation works! Thanks for the update.

Thanks for checking. I will close this issue,
