Hi all, I’m having trouble executing a .py script that sits in the directory:

/home/pi/Documents/test.py

According to @orayoflighto in this thread, he suggests adding 1 line to node_helper.js that sits in the MMM-PIR-Sensor module directory from:

        if (data.indexOf("0x120002") !== -1)
          exec("/opt/vc/bin/tvservice --preferred && chvt 6 && chvt 7", null);

to

        if (data.indexOf("0x120002") !== -1){
          exec("/opt/vc/bin/tvservice --preferred && chvt 6 && chvt 7", null);
          exec("python /home/pi/py-spidev/RPi-LPD8806/LED.py");
       }

I’ve tried this exec() below in both activateMonitor and briefHDMIWakeup function and it’s not working.

    briefHDMIWakeup: function() {
        const self = this
        exec("/usr/bin/vcgencmd display_power").stdout.on('data', function(data) {
            if (data.indexOf("display_power=0") === 0) {
                exec("/usr/bin/vcgencmd display_power 1", null);
                exec("python /home/pi/Documents/test.py")

Note, calling sudo python3 test.py in cmd line works itself. I’m having trouble figuring out why exec() is not calling in node_helper.js. Any tips on debugging this?

I tried console.log(text); in .js file. It’s not calling either (i may be totally viewing command prompt wrong to view debug message)

Thanks for reading!
