I cannot reproduce this issue. I don't have any issues with last state being restored after restarting openhab2.

Hi Bob,

I thought for clutter purposes it would be easiest to open issues on your repository.

In looking at the log files from openHab it appears the binding doesn't consistently resolve the HouseUnitCode. In the linked log file there are 3 attempts to use the external remote. Only 1 attempt determined the HouseUnitCode as E7 (which is correct)
See line: cm11a: Converted received data to human form: X10ReceivedData

log-segments.txt

Not sure if these help you.

Is there still a requirement for org.openhab.io.trasport.serial? I cannot find it in openhab2, and I don't think I have it installed. The src code imports gnu.io.SerialPort

When following through the binding code I noted these lines 86 and 92 in https://github.com/BobRak/OpenHAB-cm11a/blob/master/org.openhab.binding.cm11a/src/main/java/org/openhab/binding/cm11a/internal/X10ReceivedData.java

public static final char houseCode[] = new char[] { '-', 'E', 'C', 'K', 'O', 'G', 'A', 'I', 'N', 'F', 'D', 'L', 'P',
            'H', 'J' };
public static final byte unitCode[] = new byte[] { 0, 5, 3, 11, 15, 7, 1, 9, 14, 6, 4, 12, 16, 8, 2, 10 };

To me it appears that houseCodes B and M are missing and unitCode 13 is missing.

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.

Situation:

• 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

Situation

I have installed and am using the CM11a binding and am using with Openhab2. It works for turning on/off from PaperUI, but I have issues with OpenHab2 losing track of the state of a switch when triggered from a physical switch. When this happens I see something like the lines below in the log. Any ideas for troubleshooting?
