openhab controlling rc switch on raspberry pi

[siod]

Hi guys,

I would like to control a rc switch using my raspberry pi where openhab is also hosted. I already configured everything and it is working fine from shell e.g. as user pi I have to enter

sudo /opt/rcswitch-pi/send 00001 5 1

to turn the rc switch on. Now I tried to integrate this into openhab, without success. I added the following line to my home.items file:

Switch Light_FF_Test 		"Test Funksteckdose"	(FF_Test, Lights)	{exec="OFF:sudo /opt/rcswitch-pi/send 00001 5 0, ON:sudo /opt/rcswitch-pi/send 00001 5 1"}

I see openhab gets the command (log file) but it does not switch the rc switch. Any suggestions? Thank you!!

Is the user, that runs OH allowed to sudo?

For testing purposes I use the root user, I guess he should be able to sudo!? But I'm a total Linux noob...

Did you install the exec addon?

If OH is running as root you don't need to sudo. Haven't tried to sudo as root yet.
If OH is running with a deamon user, which certainly makes sense for production, this user may not be allowed to sudo.

Thank you Sir!

was asking in a different forum as well, nobody had the idea to install this binding first and I didn´t know a binding is needed for execution of commands...

Well then, problem solved
