Error using /dev/ttyUSB0 #5

Closed briancday closed 7 years ago

I suspect this problem is "user error", but I thought it might be helpful to pass along my experience. I'm having an issue where the binding will not connect to the USB serial adapter on /dev/ttyUSB0.

Sorry to be slow in responding. I am away from home and this is the first chance I've had to respond. Plus I only have a small Chromebook with me.

I'll be home Monday and can try to look further at my own installation then. Let me know if you make any progress.

Thanks,

Bob

  • Running Openhab2 on headless Ubuntu 14
  • Plugged CM11a into USB port via serial to USB adapter
  • Verified was working by running heyu (this may be the problem... that I'm still running heyu)
  • Moved latest jar (plus org.openhab.io.transport.serial.jar ) into /usr/share/openhab2/addons
  • Configured simple cm11a.things, and cm11a.items files under /etc/openhab2/things following examples.
  • reboot server for safe measure

Expected Result:

  • Open PaperUI -- see the CM11a binder is connected -- see things -- turn things on/off, and they work

Actual Result:

  • Open PaperUI -- see the CM11a binder is NOT connected -- see things -- turn things on/off, and they do NOT work

I’m running this on an Ubuntu VM under ESXi.  I suspect that heyu conflicts for the usb port.  I’ll uninstall and try again.

Bob:

I turned off the heyu daemon and restarted openhab2 and it is now working. 

Lesson: Don’t run heyu and openhab2 (with cm11a binding) on the same machine fighting for the same CM11a.
