Anyone know how to fix this? Things start off fine, but after a while the error below starts showing up on every write. To fix it I have to force rereading of the item config file.

Anyone have idea idea how to fix this? I am not finding much in Google, it happens anywhere from 5 min to a few hours and the fix is to restart openHAB.

No suggestion, but is this the setup with a lot of sensors broadcasting on the serial line? (i.e. the problem may be related to read or write data collisions, or rather, failure to recover from)

Good thought, but one sensor per serial port on my system.

I have the same problem for some time now. About once a week I have to restart my OH because of that. Is there any knowledge about it? Thanks!

I get this error when the device /dev/ttyusb0 is not available. When I disconnect the device and reconnect it again it appears as /dev/ttyusb1 on my raspi4.
