[SOLVED] - Missing devices are not added anymore

[vinchz31]

Hello to all,

I had successfully installed the pluggin on my raspberry PI (Buster version) and with Domoticz in version 2022.2 (Version: 2022.2 / Build Hash: eea9db734 / dzVents Version: 3.1.8 / Python Version: 3.7.3 (default, Oct 31 2022, 14:04:00) [GCC 8.3.0]) and I have been using it for a few months without any problem.

I reinstalled yesterday my raspberry with the last version of the OS (Bullseye) and installed domoticz which is now in version 2023.1 (Version: 2023.1 / Build Hash: f9b9ac774 / dzVents Version: 3.1.8 / Python Version: 3.9.2 (default, Mar 12 2021, 04:06:34) [GCC 10.2.1 20210110])

The installation of Modbus Library seems to be Ok ( from https://github.com/nmakel/solaredge_modbus ) :

After this reinstallation, I installed the Solaredge Modbus TCP pluggin as I did the previous time. It appears well in the hardware and I can configure it and add the hardware. The pluggin indicates me that the devices have been added to Domoticz but they don't appear anywhere (I don't have anything in the measurement tab and don't see anything in the new devices either).

I can see in the Domoticz Logs the following logs :

I have the impression that it does not find the Modbus library that I have installed before...

Did you encounter this problem? Do you know how to solve it?
Thanks in advance for your help

So, I've just seen that someone as a similar problem.
The module "pymodbus.client.sync" seems to have been renamed "pymodbus.client" in the last version.
So I've renamed it in the "init.py" fil of the modbus library. You can see the full detail in this post ; nmakel/solaredge_modbus#76

Now the plugin starts but i've many new errors just after and so the devices are not added...

The solution explained in #62 is working fine for me.
Thanks a lot !!!
