That is an empty message, so I can understand that the homeduino does not support that.
I see that I actually only implemented the receiving protocols except for switch1 I didn’t work on it for too long 
More work to do
If anyone finds problems in receiving please report it.
Sending is for now only supported for switch1
If i could help anyway - tell me.
Intensively testing the receiving is the most essential thing which is possible now, do your unitcode / id’s match? If not give me details of the received value (like your latest message) and what you exactly expect it to be mapped to.
Or if you can code Java you can take a look at adding the decode for switch2
I will focus on making the sending work (hopefully adding some tests to the code as well)
I think its wisest to focus first on of having this limit support working good and correct before adding other protocols.
Sorry - no experience in Java-Coding. 
I am software-developer with 25 years experience in database software dev. like Clipper and Alaska-Xbase++. How can i take a look at the source-code and which environment could i use to take a “sniff”?
What exact do you want know with “do your unitcode / id’s match?” - where should i look?
Did you use your devices also with pimatic or something like that?
Do the devices in the inbox show the same identifiers as they do in pimatic? Or anywhere else where you used them before?

Did you use your devices also with pimatic or something like that?
Yes, i used them with pimatic and they worked.
Do the devices in the inbox show the same identifiers as they do in pimatic? Or anywhere else where you used them before?
I can’t say that, because my old pimatic-sd is not working.
Then that is up to someone else, I’ll keep you posted about other progress.
Hello Martin, thank you for your work. Here is my feedback to the tests with switch 2 with your actual Snapshot:
Inbox results after pressing the remote:
I selected switch 2 (pimatic protocol: switch 2, houseCode 31, UnitCode 16), created thing and items (command and contact). The status of the switch on the control site runs (pressing the remote) much faster than yesterday (very good in my opinion). Karaf shows the following during remote switching:

I can not find any comparison with my pimatic settings (accept the protocol switch 2).
The pir1 sensor was not found by the autodetection and I don’t have the information for the device id I need for manual configuration of the thing.
I hope these informations helps you.
Looking forward to a great new binding!
If you could enable debug mode we should able to see whether the device receive any data which could potentially be matched to pir1
See: http://docs.openhab.org/administration/logging.html
log:set DEBUG org.openhab.binding.homeduino
I looked up the test-cases of rfcontrol-js and found the problems with the id / unit code.
Sending is not yet build, need some more time to construct that.
I added sending for switch2, please take a look whether it seems to make sense.
There might be some offset problems in sending vs receiving, so if it fails, try changing “25.16” to e.g “24.16” or “25.17” please report on this mapping.
Hi Martin, I will take a look at the evening and give you a feedback.
Have a nice day!
Hi Martin,
i hope this helps a little. I deleted all 433-things and press on the remotecontroller the button “ON” and then “OFF”. This is the result in the log:

But no real response from the switch.
The housecode / unit code where switched somewhere between sending and receiving, it should be improved now.
Every failure leads to news tests which stay in next to the code, so you’re helping me out in a great way.
Thanks for being a tester

Great work - thanks!
Can it be that you used to use the protocol switch5 because the message which causes the null-pointer is not compatible with either switch1,2,3 or 4 but it is with switch5.
A new version which also supports switch4 (and less cryptic logging):
outdated download
Do you mean your light actually switch… (if so Hooray)
Yes Hooray - switch2 is working!
I have no switch5 devices - i think!
I only use one remotecontrol for one switch.
Yippiiiiiiiii Switch 2 is running!!! Great work Martin!!!
I have added 3 switch2 switches with the following results:

20:19:41.389 [DEBUG] [duino.handler.HomeduinoBridgeHandler] - Checking Homeduino transceiver connection, thing status = ONLINE
I recognize that after a restart of openhab the homeduino binding is not active (transreciever offline), The log showed me the following:
19:17:26.905 [DEBUG] [duino.handler.HomeduinoBridgeHandler] - Checking Homeduino transceiver connection, thing status = OFFLINE
19:17:26.906 [DEBUG] [duino.handler.HomeduinoBridgeHandler] - Connecting to Homeduino transceiver

19:17:26.933 [ERROR] [duino.handler.HomeduinoBridgeHandler] - Connection to RFXCOM transceiver failed: null
After a reboot of the whole system the problem was still there but with the following log:
19:20:28.726 [ERROR] [l.connector.HomeduinoSerialConnector] - Event listener invoking error
java.lang.NullPointerException

After the second reboot every thing was and is fine and is running smooth.
Sometimes I have problems with the signal delivery to the wallswitches. From my feelings 
the problem was not present with pimatic. But this is “detail tuning”:-).
If you need more information, please tell me.
Sometimes i get this error:
