[SOLVED] No switch button in BasicUI

Setup, Configuration and Use Installation
4

Log file can be found under /userdata/log, but iguess it is not needed.
Your .sitemap file is absolutely wrong, it is missing major parts.
I would suggest to read
http://docs.openhab.org/configuration/sitemaps.html

@Trainer I might be wrong but I think you use openhab 1 syntax.

Have a look here for openhab 2 syntax and a basic tutorial how to use the exec binding.

Read the whole thread as there is a lot guidance to find there. Maybe this helps.

Please use code fences for your code.

Code goes here

Use the buttons over the text entry field for that.

BasicUI is unable to display anything because you commented almost your complete sitemap out.

I suggest to use a simple rule instead of the exec binding.

rule "subwoofer einaus"
when
    Item Subwoofer received command
then    
	if (receivedCommand==ON) 
	{
            executeCommandLine("/opt/rc-switch/rcswitch-pi/433Utils/RPi_utils/switchOn.sh 1")
	} 
	else 
	{
            executeCommandLine("/opt/rc-switch/rcswitch-pi/433Utils/RPi_utils/switchOff.sh 1")
	}
end

item

Switch Subwoofer “Subwoofer [%s]"

sitemap

sitemap steckdose label="Steckdose" 
{
    Frame label="Funksteckdose" 
    {
        Switch item=Subwoofer
    }
}

Thank you. i tried your version but it also didn’t work :frowning:

i got this error

23:02:21.361 [ERROR] [.ui.internal.items.ItemUIRegistryImpl] - Cannot retrieve item 'Subwoofer' for widget org.eclipse.smarthome.model.sitemap.Switch
23:02:21.369 [ERROR] [.ui.internal.items.ItemUIRegistryImpl] - Cannot retrieve item for widget org.eclipse.smarthome.model.sitemap.Switch

23:02:21.393 [ERROR] [.ui.internal.items.ItemUIRegistryImpl] - Cannot retrieve item 'Subwoofer' for widget org.eclipse.smarthome.model.sitemap.Switch

edit: Sorry my fault.
i forgot to add sudo before the executeCommandLine

executeCommandLine("sudo /opt/rc-switch/rcswitch-pi/433Utils/RPi_utils/switchOn.sh 1")
	}

Thank you.
I tried your hint https://community.openhab.org/t/no-switch-button-in-basicui/38323/5 and chanced send to codeäsend (because i only know the codesend number) but after i change it in rules

if(receivedCommand == ON){
            Remote_Send_Args.sendCommand("1397845")
        }else{
            Remote_Send_Args.sendCommand("1397844“)
        }

but i have no luck :frowning:

The error messages show that you didn’t create the *.items file.

@Trainer please post your full setup!

.rules

rule "subwoofer einaus"
when
    Item Subwoofer received command
then    
	if (receivedCommand==ON) 
	{
            executeCommandLine("sudo /opt/rc-switch/rcswitch-pi/433Utils/RPi_utils/switchOn.sh 1")

	{
            executeCommandLine("sudo /opt/rc-switch/rcswitch-pi/433Utils/RPi_utils/switchOff.sh 1")
	}
end

.items

Switch Subwoofer “Subwoofer [%s]"

.sitemap

sitemap steckdose label="Wohnzimmer" 
{
    Frame label="Funksteckdose" 
    {
        Switch item=Subwoofer
    }
}

@Trainer and the log when toggling the Switch?
Rebooting the RPI is a good idea, any time!

Did you follow the instructions?

If you need sudo there is almost something wrong with your permission. But if you really want it this is how it has to be made!
Did you execute a sudo command as user openhab/openhabian?

But lets try to get it done without sudo!

  1. Did you add Openhab/openhabian to the gpio group?
sudo adduser openhab gpio
  1. Did you try to execute the command within the user scope of openhab/openhabian?
sudo -u openhab /opt/rc-switch/rcswitch-pi/433Utils/RPi_utils/switchOff.sh 1

What is the result when executing this two lines?

13

Hey @Trainer,
Did you do this step “Set the default sitemap via the Paper UI via Configuration → Services → Basic UI → Configure, and set the Default Sitemap name” ?

Ex :

steckdose.sitemap

sitemap steckdose label=“Steckdose” {
Frame label=“Funkstechdose” {
Switch item=ONSub mappings=[“on”=“ON”, “off”=“OFF”]

Switch item=Dash_Switch
}
}

and set steckdose is default sitemap name

14
  1. i got this error message

adduser: The group `gpio’ does not exist

i got this error message with your command.

wiringPiSetup: Unable to open /dev/mem or /dev/gpiomem: Permission denied.
Try running with sudo?

15

i change steckdose to powerplugs, because my filename is also powerplugs.sitemap

16

What is your setup?

  1. Hardware?
  2. OS Version?
  3. Openhab Version?

Why is there no gpio group? Do you have wiringpi installed?

Did you try it as root?

sudo -u openhab sudo /opt/rc-switch/rcswitch-pi

I still have the feeling you did not follow every step explain in the tutorial. I would advise to start over again. Maybe with a fresh install of your Linux. And then follow every step in the tutorial.

In the second example for the led stripe i also use codesend.

  1. PRI2
  2. Linux version 4.4.32v7-aufs (max@lynx) (gcc version 4.8.4 (Buildroot 2015.02-gf4a5ebb-dirty) ) #1 SMP Fri Nov 18 23:17:35 CET 2016
  3. openhabian 2.0 / Openhab 2.2

I installed wiringpi now, but i have the same gpis group problem.

After your command i got this message:

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 others.
#2) Think before you type.
#3) With great power comes great responsibility.

[sudo] password for openhab:

i don’t know the password for the user openhab

everything works fine, so i don’t want to reinstall everything new-

18

@Trainer please post what is returned for those command, after you have rebooted the PI.

cat /etc/group

cat /etc/passwd

ls -la /sys/class/gpio/export

ls -la /sys/class/gpio

@Trainer so you miss the gpio group and all files which should have permission set for gpio are not set correctly.

Maybe a

sudo apt-get update
sudo apt-get dist-upgrade

would be the best choice. And then reinstall wiringPI

But here is what i found on how to set gpio and the file permission. I did not set it up myself.

Create a gpio group first:

groupadd gpio

add your users to that group:

usermod -a -G gpio pi
usermod -a -G gpio openhab

Test if it went right.

pi@raspberrypi:~ $ grep gpio /etc/group
gpio:x:997:pi,openhab

Reboot

Fix permissions of the sysfs GPIO file system.

sudo nano /etc/rc.local

add following to the bottom

chown -R root:gpio /sys/class/gpio
chmod -R ug+rw /sys/class/gpio

Next set up an udev rule to enable non root and gpio group user to acces GPIO files.

sudo nano /etc/udev/rules.d/80-gpio-noroot.rules

# /etc/udev/rules.d/80-gpio-noroot.rules
# Acces to GPIO without root
#
#  Change group
SUBSYSTEM=="gpio", PROGRAM="/bin/sh -c '/bin/chown -R root:gpio /sys/devices/platform/soc/*.gpio/gpio'"
# set acces permission
SUBSYSTEM=="gpio", PROGRAM="/bin/sh -c '/bin/chmod -R ug+rw /sys/devices/platform/soc/*.gpio/gpio'"

No reboot just trigger the rule.

sudo udevadm trigger --subsystem-match=gpio

But rebooting is always a good idea.

taken from here and here.

Edit: additional this has to be set

The file permission to gpiomem should look like this

$ ls -l /dev/gpiomem
crw-rw---- 1 root gpio 244, 0 Dec 28 22:51 /dev/gpiomem

If it is different change it with

sudo chown root:gpio /dev/gpiomem
sudo chmod g+rw /dev/gpiomem
21

Thank you.
I do everything you explain me, but i got the same message, if i try to use codesend without sudo

wiringPiSetup: Unable to open /dev/mem or /dev/gpiomem: Permission denied.
Try running with sudo?

22

Fresh installation of the latest Rasbpian is my last idea.

23

If someone has the same problem, after i follow this instruction, i can use it without sudo.

https://raspberrypi.stackexchange.com/questions/40105/access-gpio-pins-without-root-no-access-to-dev-mem-try-running-as-root

it should looks like this

$ ls -l /dev/gpiomem
crw-rw---- 1 root gpio 244, 0 Dec 28 22:51 /dev/gpiomem

if not, you can chance it with this commands

sudo chown root.gpio /dev/gpiomem
sudo chmod g+rw /dev/gpiomem
