I tried, it works the Pc is Off!

mkdir failed on directory /var/cache/samba/lck: Permission denied

Shutdown of remote machine succeeded
6

So the problem is somewhere else … :thinking:

7

I found the probem!

My cod is working with exec bindig v1.x but now exec bindig 2.0 is active. I saw the readme, but it’s too difficult for me now, I am newbie :frowning:

Can someone rewrite my code?

Thanks!

I trying to write exec bindig 2.0 code, but it not wok, can someone help correct it?

pc.things

Thing exec:command:micropc [command="net rpc shutdown -I 192.168.0.100 -U user%pass"]

pc.items

Switch micropc "MicroPc" { wol="192.168.0.255#D0:50:99:35:6E:BB",
			  channel="OFF:exec:command:micropc:run" }

The wol works, but the exec (power off) not.

Thanks!

Had the same Issue.

The Problem seems, that the Exec 2.0 Binding cannot handle Switches.
Could you try the following:

    String micropc "MicroPc" { channel="OFF:exec:command:micropc:run" }

On your Sitemap you can use a Switch.

If this works, then you can try to make a Rule with WOL and Exec.

Thanks for the hint, but not working :frowning:

items

String micp "MicroPcofftest" { channel="OFF:exec:command:micropc:run" }

sitemap

Switch item=micp
11

Maybe the “%” in “user%pass” is causing the problem.

But I do not know how you need to change chat.
Try “user%%pass” or “user%pass”.

12

Thanks! The user%%pass version works!

Now when I turn on the Pc, it immediately turns off :grinning:

13

If this code present, the pc turn off immediately after turning on.

pc.things

Thing exec:command:micropcoff [command="net rpc shutdown -I 192.168.0.100 -U user%%pass -f"]

I modified the items code, but nothing change, the pc turns off. It means the command in the things automaticly runs.

pc.items

Switch micropc "MicroPc" { wol="192.168.0.255#D0:50:99:35:6E:BB" }

How can I controll it with switch?

14

I found this topic, so the automatic run solved, but switch not working…

pc.things

Thing exec:command:micropcoff [command="net rpc shutdown -I 192.168.0.100 -U user%%pass -f", interval=0, autorun=false]
15

Now turn on works with wol binding, and turn off works with exec binding, but now only with two switch.

Switch mpcon "MicroPc On" { wol="192.168.0.255#D0:50:99:35:6E:BB" }

Switch mpcoff "MicroPc Off" { channel="exec:command:micropcoff:run" }

How can I put it together in one swich item, ON and OFF state?

16

By the way,

is it possible to combine Commands?

Like tapping a Switch causes WOL and then Executes a Script?

I have a problem with executing a Python script. In the script i do a WOL but this never works when executed by openhab. Permissions are set correctly.

Any suggestions?

Greetings Michael

17

Yes, it is possible:

Switch mpc "MicroPc" { wol="192.168.0.255#D0:50:99:35:6E:BB", channel="exec:command:micropcoff:run" }

wol turn on the Pc, than exec turns it off immediately.:slight_smile:

18

Thank You.

I’ll give it a try!

That worked pretty good, but instead of Number, I used Switch and the values OFF and ON so that Alexa could control turning on and off the computer.

21

Thanks for this inspiration, I adopted this to control my WIndows 10 PC, with Melissa’s idea for ON/OFF.

But I fould that something lacked, when power on or off PC by hand, Openhab did not update the status of it.

So to make it complete, I added a Switch checking presence of PC via Pingdevice, and a rule to check if the status changed “outside” of OH2. So the solution looks like this:

Thing:

Thing exec:command:holgerpcoff [command="net rpc shutdown -f -I 192.168.75.112 -U HOSTNAME/USER%%PASSWORD", interval=0, autorun=false]

Items:

Switch 			Presence_Holger_PC			"Holger PC" 				<network> 	{channel="network:pingdevice:192_168_75_112:online" }
Switch			Holger_PC_ON_OFF			"Holger PC"					<network>   ["Switchable"]
Switch 			Holger_PC_ON 				"Holger PC ON" 							{ wol="192.168.75.255#08:62:66:29:5A:F2" }
Switch 			Holger_PC_OFF 				"Holger PC OFF" 						{ channel="exec:command:holgerpcoff:run" }

Rules:

rule "Holger PC onoff"

when Item Holger_PC_ON_OFF received command
then switch (receivedCommand)
	{
	case ON: { Holger_PC_ON.sendCommand(ON) }
    case OFF: { Holger_PC_OFF.sendCommand(ON) }
	}
end

rule "Holger PC State"

when Item Presence_Holger_PC changed

then 
	
	if (Holger_PC_ON_OFF.state != Presence_Holger_PC.state) 
	 Holger_PC_ON_OFF.postUpdate(Presence_Holger_PC.state)
	end

Sitemap:

Switch item=Holger_PC_ON_OFF label="Holger PC"

With this solution, you can Power on/Shutdown PC with OH2, plus it shows correct state if you started it or shut down manually.

Hi!

I tried your code, but the state not working.

Can you help me, what is wrong with my code?

Items:

Switch Presence_Micro_PC “MicroPc2” {channel=“network:pingdevice:192_168_0_xxx:online” }
Switch Micro_PC_ON_OFF “MicroPc2” [“Switchable”]
Switch Micro_PC_ON “MicroPc2 ON” { wol=“192.168.0.255#xx:xx:xx:xx:xx:xx” }
Switch Micro_PC_OFF “MicroPc2 OFF” { channel=“exec:command:micropcoff2:run” }

Rules:

rule "MicroPc on/off"

when Item Micro_PC_ON_OFF received command

then switch (receivedCommand)

{

case ON: { Micro_PC_ON.sendCommand(ON) }

case OFF: { Micro_PC_OFF.sendCommand(ON) }

}

end

rule "MicroPC State"

when Item Presence_Micro_PC changed

then

if (Micro_PC_ON_OFF.state != Presence_Micro_PC.state)

 Micro_PC_ON_OFF.postUpdate(Presence_Micro_PC.state)

end

Hi!

I found the error in items:
Switch Presence_Micro_PC “MicroPc2” {channel=“network:pingdevice:192_168_0_xxx:online” }

The working code is:
Switch Presence_Micro_PC “MicroPc2” {channel=“network:device:192_168_0_xxx:online” }

Thanks for working solution, I got this up and running, one thing you mist is Thing configuration of your 192_168_75_112…
