you will have to install a mail transport, such as postfix. Then, simply start this script on the printer

 

#!/usr/bin/python3

import systemd.journal
import socket
from time import sleep
import smtplib
import email
from smtplib import SMTP
from email.message import EmailMessage
import datetime


def main():
  j = systemd.journal.Reader()
  j.seek_tail()
  j.get_previous()
  while True:
    event = j.wait(1000000)
    if event == systemd.journal.APPEND:
      for entry in j:
         print (entry['MESSAGE'] + " " + str(datetime.datetime.now()))
         alertmail(entry['MESSAGE'])

def alertmail(logEntry):
    # returns first occurrence of Substring
    trigger_text = 'pause'
    result = logEntry.find(trigger_text)
    if (logEntry.find(trigger_text) != -1):
        print ("Contains '" + trigger_text + "' at index:", result)
        msg = EmailMessage()
        msg.set_content(str(datetime.datetime.now()) + " \n " + logEntry)
        msg['Subject'] = ' '.join(logEntry[24:].split())
        msg['From'] = "ultimaker@mail.bellariastrasse.com"
        msg['To'] = "adriano.aguzzi@usz.ch"

        smtp = smtplib.SMTP('mail.bellariastrasse.com', port='587')
        smtp.ehlo()  # send the extended hello to our server
        smtp.starttls()  # tell server we want to communicate with TLS encryption
        smtp.login('ultimaker@mail.bellariastrasse.com', 'scrap10')  # login to our email server

        # send our email message 'msg' to our boss
        smtp.send_message(msg)
        smtp.quit()  # finally, don't forget to close the connection
    else:
        print ("Doesn't contain substring '" + trigger_text +"'")

if __name__ == '__main__':
    main()

This works on S5?  Very cool.

 

@Smithy maybe you could add a feature that installs postfix and then installs the above script?  Ha ha - your tool is getting more and more complicated all the time.  🙂

    @aag Great idea, but should work without a local installed mail transport agent as well, or do I miss something? You connect directly to the destination. 
     

    @gr5 yes, should be no problem, if aag agree with it.?

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
