actions, Execute Command, Displaying a message
#1
Hello, everyone, 
I am currently trying to turn my HDMI screen off and on again with actions. 

Now to my procedure. 
I installed cec-utils first. 
This allows me to put the monitor into standby mode and back into on mode. 
This procedure also works wonderfully in the command line. 

Now I wanted to go one step further and automate it. I connected a motion detector to GPIO 05 which acts as a trigger. 
In SK Diagnose, the motion detector runs up, which means it does what it should. 

Now to my problems: 
I wanted to display a message (for testing) as an action. That doesn't work. But I think the problem has been known for some time because I read it in the search of this problem.

Additionally I wanted to execute a command. 
echo "on 0" | cec-client RPI -s -d 1

respectively

echo "standby 0" | cec-client RPI -s -d 1

But I get the following error when I start OP in debug mode..:

MySK_to_Action_Calc instance has no attribute 'currentpath'
"standby 0" | cec-client RPI -s -d 1

Hangs the problem of looking here see Threat?

Are there ways to solve this?

@jim321  I know that you like to work with node red. I tried it. But I am too stupid. It may be quite easy, but unfortunately not for me.  Confused

Hello, Jim, 
Thanks for the code, 
Unfortunately, it's not working. 
after inserting a debug-output you get the following error message

Code:
opening a connection to the CEC adapter...
ERROR:   [            3513]    error opening serial port '1': No such file or directory
ERROR:   [            3513]    could not open a connection (try 1)
ERROR:   [            6347]    error opening serial port '1': No such file or directory
ERROR:   [            6347]    could not open a connection (try 2)
ERROR:   [            8247]    error opening serial port '1': No such file or directory
ERROR:   [            8247]    could not open a connection (try 3)
ERROR:   [            9502]    error opening serial port '1': No such file or directory
ERROR:   [            9502]    could not open a connection (try 4)
unable to open the device on port 1
When I put the command in the terminal, the TV does what it's supposed to do.

see if this fixes it..

sudo npm install serialport --unsafe-perm --build-from-source

i have tested it with inject but i don't have cec-utils installed so the command has nothing to start..but i see the command sent.

i updated the code to include inject debug..

Probably related to the thread you point to.

OK, THEN,

That could explain the problem with the command.



Why are no hints/texts displayed anymore?

Greetings Jürgen

i installed cec-utils and get the same errors.
have a look here.
https://flows.nodered.org/node/node-red-contrib-cec
https://groups.google.com/forum/#!topic/...5-oQC3MTYI

i installed this and it connects to the rpi i dont have a HDMI-CEC device to connect to so thats as far as i can go..
dont give up there's more than one way to skin a cat..

new flow i cant test should work you may need to invert the logic in the change node 0,1.

Hello,
@ Jim321
Thank you for your trouble. I couldn't insert your last flow. I don't know why. But it caused me to get a little closer to NodeRed. I managed for the first time to build a partly own flow. Now it works and I am very happy about it. Thank you for your persistence.

@Sailoog
Is it intended to fix the error with the messages in actions or do I prefer to wait for OP 2.x.x?
