Request help with rfxcom binding (not working for me)

Add-ons Bindings
1

I’m relatively new to openhab and I’m trying to use rfxcom binding with the RFXtrx433E

I’m running Openhab 1.7.1 with the Z-Wave and rfxcom binding.

zwave:port=/dev/ttyACM0

rfxcom:serialPort=/dev/ttyUSB0
org.openhab.binding.rfxcom-1.7.1.jar

Z-wave is working with no problem

RFX is not working with openhab (when I use Domoticz it works)

When I use the switch I created nothing happens.

I don’t know how to further diagnose this problem.
Any help appreciated.

Below my setting and part of error log:

openhab.log

The first thing to check when dealing with /dev/tty* is to make sure that the openhab user is a member of the dialout group. It is possible it doesen’t have permission to read/write to /dev/ttyUSB0. Though I would expect you would have the same error with /dev/ttyAMC0 so who knows.

Make sure that the rfxcom device is actually on /dev/ttyAMC0.

Beyond that we will need to wait for an rfxcom user to chime in.

I think you need to convert the HEX id to DECIMAL.

Quote rfxcom wiki:
where DeviceID is a valid wireless device identifier in decimal (not hexadecimal !).

The HEX/DEC thing stumped me also.

You can to use a site like http://www.binaryhexconverter.com/hex-to-decimal-converter

Tap in your HEX (in your case 00E7D562) and that will give you the DEC (in your case 15193442)

You still add the .3 to the number (15193442.3)

Adding:

<logger name="org.openhab.binding.rfxcom" level="DEBUG" />

to your logback.xml (put it with the other similar looking lines starting with <logger… will help (as you will see things come in, even if they are not going out)

Did you look setup symlinking your USB ports?
