@sdetweil Thanks for your answer! I will look behind the documents and try my best to get something going. 😉

@sranj ok, so u receive the trigger in the node_helper, and need to launch/exec/spawn your python pgm

so you need the child_process library
https://nodejs.org/en/knowledge/child-processes/how-to-spawn-a-child-process/

PIR uses the same library to launch the tvservice command, or vgencmd to blank the screen

@sdetweil Actualy JSON requires quotation of the key and of the value (if the value is a string)

Example of a JSON file:

{ "string": "This is a string", "bool": true, "int", 1, "float": 3.14, "arrayOfStrings": [ "string1", "string2" ], "arrayOfInts": [ 1, 2 ] }

The same can be used in a Javascript file, but as an object. You can also throw away the quotation of the keys.

If you have config file copy config.sample
Start again copy the sample file to your documents and downloads.
Remove sample from the configuration file
Start again
Remember start with {
Code
Ends in },

It’s not always easy to see what’s wrong as the code you are using could be wrong .

as l’ve not used this module l cannot say
Keep trying your get their in the end
If it go wrong it’s easy to start again.

habe alles nach anleitung verkabelt… die pins geändert vom pir …
habe pigpio installiert und rebootet
der pir reagiert auch aber bildschirm bleibt grau… dh ohne bild… monitor ist aber an.
led streifen leuchtet aber nicht…

was kann das sein
thx
