@muhackl666 i think you have to install the
And the string in your input channel has to be properly set. Please post your settings only the error is not enougth to find out the reason.
Did you do something like
Remote_Send.sendCommand("YOUR STRING")
instead of
Remote_Send_Args.sendCommand("YOUR STRING")
I 99% copy and pasted exactly what you postet in your tutorial. The 1% difference is the code I send to receiver. It’s 11111 1 1 and of cource 11111 1 0.
So there is Remote_Send_Args.sendCommand(“11111 1 1”) for example.
I manually installed regex transformation via openhab console and feature:install openhab-transformation-regex.
What else could it be?
@muhackl666 try to install the exec binding and the regex transformation from paper ui, again.
I encountered a problem with karaf and paper ui Installation.
Please clear the log then restart and post your full log.
I deinstalled the regex binding and reinstalled it - both via paper ui this time. I also installed exec transformation.
I deinstalled and reinstalled the exec binding. And this is the log:

@muhackl666 i dont see where you pressed a switch in the log. As there is no output logged from the rules and also no state change from the switches.
How does Remote_Send gets triggered to change to ON?
When the input channel in this case Remote_Send_Args is not set before triggering the execution there will be this error.
What is shown in the log when you press a switch?
PS: please use the icons above the writing field to format your code or log.
```
your code goes here

Exactly this is shown, when I switch the switch in basic ui. The switch goes to the right and after that automatically back to the left (off). In the log, that’s everything that happens:
19:41:52.043 [INFO ] [smarthome.event.ItemCommandEvent ] - Item ‘Remote_Send’ received command ON

- are you using the Powerplugs or the LEDstripes example. Please post the content of all your files. Please use the code fence for that.
- Did you try to execute the send command from the command line as user pi and it worked?
- Did you try to execute the send comamnd as user openah/openhabian, and it worked?
- And then you setted up Exec binding, transformation, the files and rebooted?
I at least miss one of this outputs in the logs.
logInfo("Power_Plugs", "Switch Socket "+ num +" to " + plug.state )
...
logInfo("Power_Plug", "Result:" + Remote_Send_Out.state )
- What is your setup RPI1/2/3, Openhabian or openhab apt-get installeld?
I’m using the Poweplugs example.

When I do:
sudo -u pi /opt/raspberry-remote/send 11111 1 1
the power outlet switches on. With 0 at the end it switches off.
When I do:
sudo -u openhab /opt/raspberry-remote/send 11111 1 1
the power outlet switches on. With 0 at the end it switches off.
Exactly.
It’s a Raspberry Pi 3 with the latest Raspbian Stretch and Openhab installed like described here: https://docs.openhab.org/installation/linux.html
via
echo 'deb https://dl.bintray.com/openhab/apt-repo2 stable main' | sudo tee /etc/apt/sources.list.d/openhab2.list
and
sudo apt-get install openhab2
and even
sudo apt-get install openhab2-addons
@muhackl666 only thing i can advise now is a fresh install of openhab or the whole pi. I have no further ideas.
But why does your switch automatically turn off again?
And what is the version of your openhab? Mine is
dpkg --list | grep openhab
ii openhab2 2.2.0-1 all openhab2
So I set up another raspberry pi3 - everything totally freshly.
And it works fine - at least in basic ui.
So something must have been misconfigured in my previous setup.
Regarding paper ui, it looks like this:
The switch can’t be used. Any hints?
Paper UI is a config and maybe testing tool. Not a user UI.
To use you need a Basic UI or an Habpanel or one of the others i don´t now of.
No problem. I’ll get along. You helped me a lot and openHAB is now a lot more useful for me.
Many thanks again.
Hey Josar,
thanks for your great tutorial - I’ve been searching for a way to control my powerplugs via Alexa and openHAB for a long time. Your solution works fine for me.
But sometimes my transmitter signal gets lost or isn’t recognized by the receiver. I’d like to send every command multiple times to make sure the digital and physical state of the device are equal. What is the smartest way to do this? In this thread I found a few helpful things but I don’t know how to put them together.
I’m not sure if this works if I set the thing’s autorun to false:
rule "Poweroutlet B"
when
Item Power_Plug_Socket_B received command
then
var i = 0
// wait for transmitter to be free
// State will be NULL if not used before or ON while command is executed
while(Remote_Send.state == ON){
Thread::sleep(500)
}
if(receivedCommand == ON){
Remote_Send_Args.sendCommand("11111 1 1")
}else{
Remote_Send_Args.sendCommand("11111 1 0")
}
// send the command e.g. 5 times
while((i=i+1) < 6){
Remote_Send.sendCommand(ON)
// wait for the command to complete
while(Remote_Send.state != OFF){
Thread::sleep(500)
}
}
logInfo("Power_Plug", "Result:" + Remote_Send_Out.state )
end
I know that I could just edit and test the rule until it works but I’d like to get into openHAB and understand how it’s working.
Best regards
Jannis
Thank you @Josar for this great thread.
I’m up and running now, except for one thing, for which I would really appreciate your input.
I’m using the exec binding to control my Air Conditioning unit (AC) through a WEB interface.
With the control (aka POST) bit in place, how would you go about getting polled (aka GET) values returned by a bash script into the exec:command framework?
(My current script returns “0” or “1” for OFF or ON, for temperature values strings like “23.5” are returned.)
I want to regularly refresh/update AC values in OH2 because AC parameters can be changed from phone APP(s) or even the AC remote. (There is no working OH1/OH2 binding for my AC)
Cheers
@Jannis501 i would also do it like this. But did not test it for validity.
But i think the command will automatically send 3 times by the routine. So you should think about better placement or antenna setup.
Maybe you need an additional sleep after the wait for the transceiver to be available again.
Looks interesting, but I already done the http part in my bash scripts.
I feel that the polling bit is the only thing lacking from the exec2 binding, but it can perhaps be achieved with the use of a timer and a post-update into the virtual switch.
Then you have multiple options.
- set up a thing with Intervall for each value you want to update.
- set up a rule with a cron expression. And trigger the updates in the rule.
But i still think your solution has more overhead then doing it with the http binding.

so after reading and going through a lot of sites and this page here I was not really able to get it happening but I think I’m close to to where I wanted to be but please I need some more help, I would like if someone can point me to the right path for setting up my 433MHZ door sensor. I have installed 433UTILS into my Pi since I find it easier to deal with, please tell me where I went wrong, here is what my items, rules and things look like :
RULES : rule "DOORSENSOR"
when
Item DOORSENSOR chaned to OPEN
then
postUpdate (433Utils/RPi_utils.state == OPEN){
}
if(receivedCommand == 14756833){ postUpdate DOORSENSOR.statusCommand =(“OPEN”) }else{ if DOORSENSOR.stateCommand =(“CLOSE”) postUpdate (433Utils/RPi_utils.state == CLOSE) }
end
ITEMS : Switch DOORSENSOR { channel=“exec:command:./RFSniffer:run” }
