i saw there are some issues with the driver , and maybe this is the only issue,
but i could understand the difference between switch to register …

any particular solution that may work?

Hello Porainir,
I’m a new enthusiast user at home assistant.
I bought a card as well as the one you put in the picture, modbus.
I did some tests but I was not able to use it with home assistant.
Did you do it?
Could you help me?
Thank you very much

Thanks for the reply
The version of home assistant is: Home Assistant 0.84.3 with HassOS 1.13
For the other questions I have attached a photo.

Hey the problem , is subjected to the adapter you need special driver, i suggest to change the adapter.
