Hey there @martgras, mind taking a look at this pull request as it has been labeled with an integration (modbus_controller) you are listed as a code owner for? Thanks!

Hello @dudanov, is this just code refactoring or what are you actually fixing?

Hello @dudanov, is this just code refactoring or what are you actually fixing?

Hello. I wrote that this is a fix, not a refactoring. You can see the changes in the code. In short, incorrect register conversion has been fixed.

Thank you for the fix. I don't like bureaucracy either, but it helps describing what failed and when, what you are fixing and how in the PR OP, like all other PRs, so it is easier to prioritize without having to look at the code in detail.

btw, clever and succint conversion there, code is much cleaner now.
