Hi all. I have a USB IR Reader attached to a Raspberry PI, which works correctly with the Smartmeter binding. That is, it works correctly for a period of time before it suddenly stop working, spitting out the error “Serial port /dev/ttyUSB0 not found or port is busy”. Disabling and re-enabling the Thing doesn’t help. Restarting openhab (“sudo systemctl restart openhab”) does the trick though. This leads me to believe that it’s the java process itself that locks the port.
Any ideas on the cause of this or a possible work around (that could preferably be implemented as a rule)?
