EMMA-02 connectivity working on 1.4.1 but not working on 1.5.0.beta2

Hi There,

I thought my experience could give you some insights. On version 1.4.1 i can include my Smartguard with EMMA-02 by connecting over TCP port 502 and slave 3. I installed version 1.5.0 beta2 to test it out. On this version when i try to connect to the same IP same TCP port and slave ID id does not work i get an unexpected error and the log is stating this:

Logger: custom_components.huawei_solar.config_flow

Unexpected exception while connecting via ModbusTCP

Traceback (most recent call last):

^^^^^^^^^
File "/usr/local/lib/python3.13/asyncio/locks.py", line 213, in wait

asyncio.exceptions.CancelledError

My server versions are:
Core 2025.1.2
Supervisor 2024.12.3
Operating System 14.1
Frontend 20250109.0

Is this issue because of the pymodbus version?

Same here but 1.5.0a1 is working for me.
