hi,

as a matter of fact, there is nothing created in mqtt.

could you guide me on a solution ?

Can you check what version of minimalmodbus you have installed?

If you have <2.1, please install minimalmodbus==2.1.1

As read_long with number_of_registers was introduced in version 2.1.

[micclfr]

thank you.
my minimalmodbus was 2.01, and my inverter's Modbus adress was not 1.
Still, no luck, same errors

Sorry I'm struggling to understand your last sentence.

Can you send me the output of pip3 list ?

Thanks

[rjpearce]

I have been unable to reproduce this issue. If you can provide me with the output from pip3 list that shows you minimalmodbus>=2.1.1 then I will gladly re-open.
