@poopyurinal so, does mirror app start? but assistant doesn’t work ? are you using pm2? to control Mirror autostart?

starting a pgm at boot

https://timleland.com/how-to-run-a-linux-program-on-startup/

you might need two? on the py and one the mirror app?

what is the reported problem? and where?

@s-monti-74 way cool congrats!

@s-monti-74

I think the module will read the serial port , and map that to some notification for other modules

devices: {
        '/dev/ttyACM0': {
          messages: {
            'Gesture: UP': [    < ---- message it reads from serial port (in your case rfid tag value)

ok, got it… you don’t KNOW if you got it in the pi yet…

this module should work for you

@s-monti-74 so, once again, what code running on the pi gets the rfid value?

python script or ???

@s-monti-74 said in Serial Comunication with Arduino:

MMM-ProfileSwitcher

so, you would lookup the profile name from the rfid tag, and send a messge for that profile

from the MMM-ProfileSwitcher readme

this.sendNotification('CURRENT_PROFILE', 'DESIRED_PROFILE_NAME_HERE');

@s-monti-74 wht do you want to do with the rfid tag value? besides display it? use it as a profile id?

How did u implement the pi side? Python?
