From one moment to the next the USB access in OH1 is broken. At night I turned off all lights using OH and the next morning the coffee machine was not on…
I’ve been running with this setup for almost a year without any issue.
RPI3 with 3 USB connections: Heat metering (dsmr binding), smart meter (iec6205621 binding) and zwave (zwave binding). All three stopped working.
USB ports are configured through udev and owned by root/dialout. Openhab is member of dialout.
From openhab start script:
-jar $cp $
Running openhab as root from the command line (start.sh) does not make any difference.
Extracts from the logs:
2017-04-16 12:59:35.393 [ERROR] [b.z.i.protocol.ZWaveController:349 ]- Serial Error: Port /dev/USBZWAVE2 does not exist
2017-04-16 13:00:33.562 [ERROR] [binding.dsmr.internal.DSMRPort] - Could not open port: /dev/USBDSMR
2017-04-16 12:59:33.285 [ERROR] [iec6205621meter.internal.Meter] - Failed to open serial port /dev/USBIECB: Serial port with given name does not exist
I checked the Zstick in a MAC on OH2, no issues.
To me it looks like an OS issue, but I cannot be sure.
Any pointers are appreciated.
