NOTE: I found that the highest version of pymodbus that would install is 2.5.0 in Buster, kernel: 5.10.103-v7l+, RPi 4.
I had problems with Bookworm, so I decided to inistall period software for the greatest compatibility.
A lightning strike damaged my solar power station and I'm rebuilding the software environment. The system ran several years without much of a problem, on a RPi 3b+. However, in all that time, I don't think I ever ran the scripts in question, so I don't know for sure if this an update problem or whether the scripts would never have ran in my systrem configuration..
The two scripts ane not neccessary in my system, so this is not an urgent or even critical issue. Thanks for the software.
Installed latest version your software.
Running.
Tried the 'info.py' and 'readall.py' scripts in python2 and 3:
`pi@raspberrypi:/var/www/html/epsolar $ python info.py
Traceback (most recent call last):
File "info.py", line 3, in

ImportError: cannot import name ModbusSerialClient
pi@raspberrypi:/var/www/html/epsolar $ python3 info.py
