PIR and config.js

N6NG

I saw the thread about running the script below to see if the screen would react to the vcgencmd.

/usr/bin/vcgencmd display_power 0; echo “Display should now be off”; sleep 20; /usr/bin/vcgencmd display_power 1; echo “And now it should be on again”

I did so and the screen did as advertised… My problem is I’m not sure how to incorporate this into the config.js to make my PIR work properly.

{
		module: "MMM-PIR-Sensor-Lite",
		position: "top_right",
		config: {
			sensorPin: 2, // GPIO pin
		        commandType:  "vcgencmd",  
                                }
}

Can one of you smart people give me some ideas?
Thanks all…

@N6NG those commands should be what the pir module execute.

examine the node_helper.js

@N6NG I have just spent the evening getting my MM working with this module. What do you want this module to do? turn the screen off 20 seconds after motion is detected?

I am using the latest version of Desbian so i had to used the default xrandr command. but I seem to have got it working fine. I was also having issues with GPIO pin 2 so I changed it to pin 22.

If it helps, I can share my config file for this module.

@shall_ Yes… I would like to look at it… If you would like not to post it to public, you can send it to my protected email

@shall_ Although it might help others if you don’t mind posting it here…
Thanks

I never saw an example of what the config.js would look like to have the vcgencmd be used to turn the screen on and off. Would someone post a part of a config.js with this in use so I can get a look at how it would be used? I would appreciate it.
Thanks all

@N6NG edit the node_hekper.js and see what it does. change as u see fit

N6NG

@sdetweil Use the whole node_helper.js except as I modify it? The only thing I would modify would be the sensor pin number… All else would stay the same?
Thanks

N6NG

@N6NG Do I modify it where it is or do I copy it into the config.js ? If I modify it where it is and change the sensor pin what would I put in the config.js?

@N6NG said in PIR and config.js:

@N6NG Do I modify it where it is or do I copy it into the config.js ? If I modify it where it is and change the sensor pin what would I put in the config.js?

all you are doing is changing the vcgencmd string

exec(“…”)

then everything else is normal in config.js

pin and commandType (I didn’t look at the module doc)

N6NG

@sdetweil Ok Sam… thanks I’ll give it a try and see how it does… will let you know…

@N6NG When I put the
exec (“/usr/bin/vcgencmd display_power 0”, null);
in the config.js I get an error. When I run npm run config:check it says that line has an Unexpected token
“/usr/bin/vcgencmd display_power 0”

@N6NG be careful copy/paste, the forum without code marker uses the slanted. single and double quotes. used by word processing apps

JavaScript expects the upright versions

N6NG

@sdetweil I typed it in straight from the keyboard… No copy and paste at all… Still the still the same error…

@N6NG that doesn’t go on config.js, it goes in the node_helper.js to replace what it already does, if it’s different.

N6NG

@sdetweil Oh… ok… thanks… I’ll do that.
