The error is missing after a reboot, but the switch not working. :unamused:

rule "MicroPc on/off"

when 
      Item PCONOFF received command
then
switch (receivedCommand){
     case 1: {
            mpcon.sendCommand(ON)
logInfo("check.rules", "switch case 1 triggered")
     }
     case 2: {
             mpcoff.sendCommand(ON)
logInfo("check.rules", "switch case 2 triggered")
     }
}
logInfo("check.rules", "finished rule")
end

what is in events.log if you switch mpcon and mpcoff via sitemap? the command sent then must be the same then sent via the rule.

events.log

openhab.log

nothing

odd. Designer should have spotted “item” instead of “Item”. try:

when
      Item PCONOFF received command
then

with a capital I in “Item”…

12

It works!!!

Thank you very much! :smile:

Here is the full working code:

sitemap:

Switch item=MPCONOFF mappings=[1="ON",2="OFF"]

items:

Switch mpcon "MicroPc on" { wol="192.168.0.255#D0:50:99:35:6E:BB" }
Switch mpcoff "MicroPc off" { channel="exec:command:micropcofft:run" }
Number MPCONOFF "Micro Pc"

rules:

rule "MicroPc onoff"

when Item MPCONOFF received command
then switch (receivedCommand)
	{
	case 1: { mpcon.sendCommand(ON) }
    case 2: { mpcoff.sendCommand(ON) }
	}
end

things:

Thing exec:command:micropcofft [command="net rpc shutdown -I 192.168.0.2 -U user%%pass -f", interval=0, autorun=false]

Hi, got the some requirement for my Kodi Media Center. I resolved it with following

items :

String wz_Kodi_systemcommand "Systemcommand"         { channel="kodi:kodi:bb8285a3-8aac-bcdd-9fe4-a16af591dbc8:systemcommand" }
Switch Fernseher_Wohnzimmer     "Fernseher Wohnzimmer"   (Status, Network) [ "Switchable" ]     { wol="192.168.1.255#XX:XX:XX:XX:XX:XX", nh="192.168.1.xxx:8080" }

rules :

when
        Item Fernseher_Wohnzimmer changed
then
 if (Fernseher_Wohnzimmer.state == OFF) {
        wz_Kodi_systemcommand.sendCommand("Shutdown")
  }
end

Hello SzilagyiR,
I’m trying to use your approach. OpenHAB is sitting on the RPi 192.168.0.4 and I’m trying to ON/OFF computer 192.168.0.2
I did install exec binding and wol binding.
Copy and past your code to correct files.
I did change user%%pass to my windows 10 login and password.
Thing is pointing to 192.168.0.2 and wol="192.168.0.2#MAC of the computer.

Is it correct approach?

16

Hi!

Yes it is seems to be correct! In user%%pass you must keep double % between the user and the pass!

17

Hello, I tried it the same way as you did

added
Switch item=MPCONOFF mappings=[1="ON",2="OFF"]
to my sitemap

added this items in my .items file
Switch mpcon "MicroPc on" { wol="192.168.1.255#D4:BE:D9:A4:38:90" }
Switch mpcoff "MicroPc off" { channel="exec:command:micropcofft:run" }
Number MPCONOFF "Micro Pc"

created a .rules file with this:
rule “MicroPc onoff”

when Item MPCONOFF received command
then switch (receivedCommand)
    {
    case 1: { mpcon.sendCommand(ON) }
        case 2: { mpcoff.sendCommand(OFF) }
    }
end

and created an things file with this content:
Thing exec:command:micropcofft [command="net rpc shutdown -I 192.168.1.255 -U user%%pass -f", interval=0, autorun=false]

ofcourse i changed user and pass with my windows login details

Now the WOL is working fine but nothing happens when I try to use the OFF button.

Any suggestions on how I could fix this problem ?

18

Your rule is sending ON in both cases…

19

Thank you for your input Hans!

I tried to change it to OFF for the second case but it is still not working.

Wake on Lan is working perfectly, but shutdown is not, any suggestions, on what I could try next ?

20

try if your command is working by entering it in the shell

21

I just checked the logs in openhab2 and it shows me this

2017-12-16 18:57:06.868 [WARN ] [ome.core.thing.internal.ThingManager] - Cannot delegate update ‘OFF’ for item ‘mpcoff’ to handler for channel ‘exec:command:micropcofft:run’, because no thing with the UID ‘exec:command:micropcofft’ could be found.

What does this exactly mean? (Never coded before so I am not sure what to do now)

22

check PaperUI for your mpcofft Thing, does it exist ? Is it online?

23

The thing is not there… But there should be, right?

I mean I have a it in my .things file in /etc/openhab2/things folder (I am using openhabian)

Thing exec:command:micropcofft [command="net rpc shutdown -I 192.168.1.255 -U user%%pass -f", interval=0, autorun=false]

Any idea why it is not shwoing up in PaperUI ?

24

You should find it under config -> things in PaperUI
Are you sure You have Exec2.0 Binding installed?

Oh wow, thank you so much!

I was so sure I have installed it already but that must have been, before I resetted everything to have a clean install. Forgot to install it again.

I could have searched for days for the error. Thanks a lot!

kind regards,
salexes

I know I asked you already alot today but I would like to ask one more thing.

After Installing the exec binding again I also installed the regex binding in order for the exec command to work.

While doing so i received an error: Failed installing 'openhab-transformation-regex': Error restarting bundles

Could you maybe take a look, maybe you already know this kind of error and know an quick solution to it.

I think because of the error described above the shutdown command is still not working

Thanks it advance.

kind regards

29

Tried that, did not change anything. Sadly I am unable to install any transformation bindings. So that means I can not use the exec solution (Wol & exec binding -> power On and Off Pc), correct ?

What other options do I have? Or what else can I try to get it working?
