Pimatic-Shell-Switch General Problem

---

Is it possible that i am so stupid, or is there something wrong with the Shell-Switch Plugin.
Here´s my problem. I am going to make a general switch for any av devices, such as av-receiver dreamboxen,.etc

This config does not work,

"devices": [
    {
      "id": "dreambox",
      "name": "Dreambox",
      "class": "ShellSwitch",
      "onCommand": "curl --silent http://dm7020/web/powerstate=4",
      "offCommand": "curl --silent http://dm720/web/powerstate=5",
      "getStateCommand": "if [[ $(curl -s http://dm7020/web/powerstate? |grep '<e2instandby>' | cut -f2 -d '>'| cut -f1 -d '<') = 'false' ]]; then echo on; else echo off; fi",
      "interval": 1000
    }

by manually running in the bash console it will work

where´s the problem

This config does not work,

any log output?

What exactly is not working? On? Off? Status?

maybe put that if into some shellscript, never tried that directly in the device

curl

We had a similar case where /usr/bin wasn’t part of the default shell environment. Try to give the full path for the curl command, e.g.

“onCommand”: “/usr/bin/curl --silent http://dm7020/web/powerstate=4”,

many thanks for yout quickly response, but the problem isn´t the on of command. my problem is the getstate command…
every enigma2 receiver gives thefollowing output…

question:

curl -s http://192.168.1.55/web/powerstate?

answer:

<?xml version=“1.0” encoding=“UTF-8”?>
<e2powerstate>
<e2instandby>true</e2instandby>
</e2powerstate>

As you can see, i have to invert the state.

when im doing this as getstatecommand:

curl -s http://192.168.1.55/web/powerstate? |grep ‘<e2instandby>’ | cut -f2 -d “>”| cut -f1 -d “<”

it works, but the state is inverted.

to build a generic shellswitch it will be nessesary to command like this…

curl http:///blabllaaa; if blubblub; then echo on; else echo of; fi

In my command with the if than else … the return is ever false.

but in the normal console the output works

could you pls. check your off command. either it’s a typo here or in your config ! there’s a 0 missing …

I don’t know if bash scripts are supported as a command, as suggested create an getEnigmaPowerstate.sh with the contents of your device and execute this in the getState.

Such devices with simple web APIs are another use of this suggested plugin
https://forum.pimatic.org/topic/1696/regex-website-parser

Sadly I didn’t find the time to start any implementation and there are other plugins in the back of my head.

@bootinterupt For future postings please quote code and command sequences as described here: https://forum.pimatic.org/topic/1179/how-to-post-code-on-the-forum

Thanks!

in my actual pimatic i use multiple sh scripts to do that, and that works. But the way to make it use is to work with dummy shellswitches, many rules, log reader and logfiles with an tmpfs filesystem, to reduce the amount of writing do the sd-card.
That is not very smart.
it was much more smarter to do this directly in pimatic, because the state from every device atribute is directly useable in the pimatic variables.

ps: yes…copy and paste error…dm7020 instead of dm702…but this is not the problem…

can someone tell me, how it is possible to execute complex bash scripts directly in pimatic without external sh script files. Is there an especially syntax needed instead of normal working bash syntax.

To solve this problem is very usefull for anyone, this is not only for me helpfull. So please dear developer, can you solve this problem.

Ps: the pimatic developer team is making a great job …!!!

@bootinterupt Please provide log output, thanks

I think you have to escape the [[.
Try:
"getStateCommand": "if [[ $(curl -s http://dm7020/web/powerstate? |grep '<e2instandby>' | cut -f2 -d '>'| cut -f1 -d '<') = 'false' ]]; then echo on; else echo off; fi",

or better:
"getStateCommand": "curl -s http://dm7020/web/powerstate? |grep '<e2instandby>' | cut -f2 -d '>'| cut -f1 -d '<' && echo 'off'|| echo 'on'",

(I’m not sure whether the “;” is somehow falsly interpreted by pimatic.)

Hello dear community,

with the help of an workmate on my working place i have found the mistake.

This doesn´t work:

{
      "id": "dream_7080",
      "name": "DM7080",
      "class": "ShellSwitch",
      "onCommand": "curl --silent http://dm7080/web/powerstate=4",
      "offCommand": "curl --silent http://dm7080/web/powerstate=5",
      "getStateCommand": "if [[ $(curl -s http://dm7080/web/powerstate? |grep '<e2instandby>' | cut -f2 -d '>'| cut -f1 -d '<') = 'false' ]]; then echo on; else echo off; fi",
      "interval": 1000
    }

This works

{
      "id": "dream_7080",
      "name": "DM7080",
      "class": "ShellSwitch",
      "onCommand": "curl --silent http://dm7080/web/powerstate=4",
      "offCommand": "curl --silent http://dm7080/web/powerstate=5",
      "getStateCommand": "if [ $(curl -s http://dm7080/web/powerstate? |grep '<e2instandby>' | cut -f2 -d '>'| cut -f1 -d '<') = 'false' ]; then echo on; else echo off; fi",
      "interval": 1000
    }

The problem was the double [[ ]]…

But another mistake is printed at the pimatic website, manual for Shell-Switch-Device

{ 
  "id": "light",
  "name": "Lamp",
  "class": "ShellSwitch", 
  "onCommand": "echo on > /home/pi/switchState",
  "offCommand": "echo off > /home/pi/switchState",
  "getStateCommand": "echo /home/pi/switchState",
  "interval": 10000
}

The “getStateCommand” Example will not work…
If it is possible, please correct that.

What do you mean by it doesn’t work? Can you please provide more details, please.

EDIT: … and, please, quote code and command sequences in your posts as advised earlier. It is is important as the the forum software transforms some characters in normal texts such as quotes. Thanks!

a command like

“echo /home/pi/switchState”

as shown in the example will not work, because

the returncode in this case is the string
/home/pi/switchState
an not the content of switchState

But i have zhe next problem when i am creating the
shellswitch for a yamaha av receiver.

also this code in bash is working…

curl --silent -d “<YAMAHA_AV cmd=“GET”><Main_Zone><Power_Control><Power>GetParam</Power></Power_Control></Main_Zone></YAMAHA_AV>” http://192.168.1.13/YamahaRemoteControl/ctrl | grep On | cut -f5 -d ‘>’| cut -f1 -d ‘<’

the return code is “on” or “off”

In pimatic config.json this will not work because auf the " in the code

is there a various syntax possible to fix it.?

use the \ as an escape character

curl --silent -d \“<YAMAHA_AV cmd=\“GET\”><Main_Zone><Power_Control><Power>GetParam</Power></Power_Control></Main_Zone></YAMAHA_AV>\” http://192.168.1.13/YamahaRemoteControl/ctrl | grep On | cut -f5 -d ‘>’| cut -f1 -d ‘<’

thanks for your idea, i have tested this
put that won´t work

this command…curl --silent -d \“<YAMAHA_AV cmd=\“GET\”><Main_Zone><Power_Control><Power>GetParam</Power></Power_Control></Main_Zone></YAMAHA_AV>\” http://192.168.1.13/YamahaRemoteControl/ctrl | grep On | cut -f5 -d ‘>’| cut -f1 -d ‘<’

will result…

bash: Syntaxfehler beim unerwarteten Wort »<«

in bash console, and in config.json the state is always “null” because of syntax error
