Modbus / Serial Connection with USB

Looks like you were right.
The permission problem has been solve. Thank you very much.
I know have another problem. :smiley:

Dont know what this is right now, but I will figure this out.
Thank you very very much!

Edit:

Nope. I was wrong. After i made a little change to the thing the permission error immediately came back:

I once did on a windows machine a serial connexion to an deye inverter and got errors like yours but the values keept coming so i just ignored it. Maybe your slave doesn’t like being called so often.
Did you read this whole thing https://www.openhab.org/docs/administration/serial.html

Thank you for your help. I did try this with another tool (modpoll) and the amount of “calls” in this short time havent been a problem yet.
So i would guess, it would be fine. But I also changed the polling interval to 30.000

Best wishes
Marcel

Maybe try to change adapter i stoped using the black one and i am using the blue ones I have ten in stock just in case.

:smiley: :smiley: :smiley:
Good to know haha. But to be honest… it looks like I finally made it.

I changed the Bridges “Time Between Transactions” to 30.000 ms.
Now i only have this problem left:

But this might be a problem with the right registers / addresses.

I was right.
I changed the Poller Infos to a Register I know is working…
And now… Everything seems to be working. :smiley:

Thank you very very much @all!
