La multiprise Silver Shield Gembird's : réglage sous Linux (KDE4) à partir du fond d'écran au moyen du plasmoïde USB-Steckdose.
... plus [télécharger comme ZIP]

The plasmoid "USB-Steckdose" allows you to click icons at the desktop to switch the sockets of your power outlet strip (Revolt INtelli-Plug, Gembird SIS-PM, 4 sockets) on and off. The icons show the states of the sockets (on/off).

1. Linux, KDE4 --- the plasmoid was developed on Debian Squeeze, KDE 4.4. Other distributions were not tested, but should work as well.
   
   
2. Outlet strip:
   • A USB power outlet strip (Revolt INtelli-Plug, Gembird SIS-PM).
     
   • The programm: sispmctl (http://sispmctl.sourceforge.net).
     
   • Both plugged and installed in a full functional way. For exemple, it should be possible to work in the terminal as root with
     sispmctl -o 1
   
   
3. The programm/package: sudo.
   In /etc/sudoers (to edit only with the command "visudo", not in an ordinary editor!!! Read the man-page of visudo!!!) should be a line like:
   username ALL=NOPASSWD: /usr/bin/sispmctl
   Take care of writing this line behind other lines as for exemple
   root ALL=(ALL) ALL
   because order of the line is relevant in processing /etc/sudoers! After this it should be possible to run
   sudo sispmctl -o 1
   as non-root user in the terminal.
   
   
4. Other programs/packages:
   • debian package "plasma-scriptengine-python" (packages.debian.org/squeeze/plasma-scriptengine-python)
   • Therefor you need "phython" and "python-kde4" what is normally already installed. Otherwise it will be installed automatically while installing "plasma-scriptengine-python".

1. Unpack "steckdose-plasma.zip" in your home folder, e.g. run in the terminal in your home folder:
   unp steckdose-plasma.zip
   
2. Install the plasmoid with "plasmapkg":
   plasmapkg -i steckdose-plasma/
   
3. Add the plasmoid as an plasma applet to the desktop:
   1. Push the right mouse button on the empty desktop
   2. Add applet ...
   3. Drag and drop the "USB-Steckdose" onto the Desktop

• Problem: "Script does not run"
  Solution: Possibly you use Latin-9 font encoding and these files are written in UTF8. Try to replace or get rid of all ä/ö/ü special characters.
  
• Problem: "The plasmoid works but is not showing any pictures. The images are successfully installed."
  Solution: In debian jessie plasmoids are run in $HOME. Paths of the images should be relative to $HOME or absolute.
• Problem: "In debian jessie the plasmoidviewer is missing."
  Lösung: plasmoidviewer has apparently been moved to the PlasMate project with the KDE 4.10 release. In a blog entry of 2012 it says you can still get it from the plasmate git repository. You could also try plasma-windowed (part of the package kde-workspace-bin in jessie) in order to run individual plasmoids in a window.

1. The icons show the state of evey socket of your power outlet strip, that means ON or OFF.
   
2. Click at one icon, to switch the socket, that means OFF or ON.
   
3. If you switch the socket by other means than this plasmoid (e.g. another programs or via terminal) the state of the buttons will be automatically updated after 5 seconds.

Deinstall the plasmoid: plasmapkg -r steckdose-plasma/
Edit the source code. Reinstall the plasmoid.

1. If you want to change the icon in the control panel of the plasma applet:
   In steckdose-plasma/metadata.desktop:
   - adapt the line "Icon=/salz-on.png"
   
   
2. If you want to change the time intervall (5 seconds) of the automatic updates:
   In steckdose-plasma/contents/code/steckdosen.py:
   - adapt "RefreshInMilliSekunden=5000" in section "1.FIXME"
   Shorter intervalls (z.B. 500) could lead to a high system load caused by the sudo calls!
   
   
3. If you need to change the assignment without changing the buttons:
   In steckdose-plasma/contents/code/steckdosen.py:
   - adapt the string variables of the socket (=Steckplatz) in section "2.FIXME"
   
   
4. If you want to change the images of the buttons:
   In steckdose-plasma/contents/code/steckdosen.py:
   - adapt the paths of the icons in section "3.FIXME"
   Parameter of the icons: 100x100 Pixel, resolution: 72x72 Pixel/Inch
   
   
5. If you need less sockets, because your outlet strip has less sockets:
   Remove or adapt the source code of steckdose-plasma/contents/code/steckdosen.py:
   - delete/adapt the global variables
   - delete/adapt string variables of the socket (=Steckplatz)
   - delete/adapt the paths of the images
   - delete/adapt the position of the icons in the widget
   - adapt the function changeXyzZustand
   - adapt the buttons in initExtenderItem
   - adapt/delete the functions clicked1, clicked2, ...
   - adapt the function dataUpdated
   
   

An easy way to actually work on the source code of steckdose-plasma/contents/code/steckdosen.py and steckdose-plasma/metadata.desktop would be:

1. Close all instances of the plasmoid on the desktop and deinstall the plasmoid with "plasmapkg":
   plasmapkg -r steckdose-plasma/
   
2. Edit the source code and reinstall the plasmoid with "plasmapkg":
   plasmapkg -i steckdose-plasma/
   
3. Have a look at the plasmoid with "plasmoidviewer" instead of adding it to the desktop over and over again:
   plasmoidviewer steckdose-plasma/
   In addition you'll get if necessary all the error messages on the terminal.

Even more easy: Each time after editing and saving the changed source code you run this one-line-command in your terminal/bash:
plasmapkg -r steckdose-plasma/ && plasmapkg -i steckdose-plasma/ && plasmoidviewer steckdose-plasma/

This plasmoid revised and adapted for debian jessie from Rainer Dorsch in 2015: netcup.bokomoko.de/~rd/steckdose-plasma.tgz

The script steckdosen.py was written by Annette Huck (annette at hopfenwiesen dot de). The pictures lampen-on.png, lampen-off.png, glaskugel-on.png, glaskugel-off.png, salz-on.png, salz-off.png, klavier-on.png, klavier-off.png, update.png, update-jetzt.png were drawed by Annette Huck (annette at hopfenwiesen dot de) with Gimp 2.2/2.6.
