Shutdown Pi using exec binding in OH2.1 (openhabian)

[Alexaas]

Hi,
I am running openhab 2.1, installed via openhabian on a raspberryPi 3.

In OH 1 I had the following item which was working fine:
Switch ShutdownPi “Shutdown Pi” (gPi) {exec=">[ON:sudo shutdown now]"}

In OH2 I have the following setup but nothing happens when I press the switch:

Thing exec:command:shutdownpi [command="sudo shutdown now"]

Switch ShutdownPi "Shutdown Pi" <computer> (gPi) {channel="exec:command:shutdownpi:run"}

Any idea?

Thanks and Regards,
Alex

You have given the openhab user sudoer permissions to run shutdown without requiring a password?

@Alexaas maybe the first link allready helps you.
If it still does not get executed you can take the long way with a rule, similar setup as the second link.
The long way may also help you debugging by logging the returned massage from the command line.

OpenHAB sudo [Exec Binding]

There are situations where you want to use the Exec Binding to trigger something. Sometimes you need the sudo privilege to do this. I would rather try some group specification to reduce the user rights to a minimum, but here is how i got openHAB to be able to execute sudo. Try executing a command as openhab sudo -u openhab sudo -l We trust you have received the usual lecture from the local System Administrator. It usually boils down to these three things: #1) Respect the privacy of other…

OpenHAB Exec Binding explained in detail on 433MHz radio transmitter example

This is a example thread to show how the exec binding 2.x works with detailed explanations. This tutorial only works since openHAB 2.3.0 Build #1212. I set up a fresh installation of “Raspbian GNU/Linux 9 (stretch)” and installed OpenHAB just followed my own thread and found some more information i missed at the first time. It is based on the Tutorial from here. First make sure you connect your transmitter with the Raspberry like follows. Have a look at the RPI pinout. Pin ATAD Data to 11 - …

Thanks. That worked. BUT it ended in an endless loop because everytime openhab started up the Thing was executed and the pi restarted or was shutdown I had to be fast to fix this…

I knew there was a reason I’m not very positive about OH shutting down the system it is running on.

There are some ways I think you can address this problem but it is going to require you to abandon theExec binding in favor of using executeCommandLine from a Rule.

Essentially you need to convert your Switch to a proxy and create a rule that only triggers when that Proxy Item receives a command ON.

That should take care of the loop.

Yes, I already had the same idea. Thanks
