Monitor Mojo outages with Python and Skype

It is a script that Python monitors the stop of the 3D printer Mojo and notifies you via Skype.

Monitor Mojo's logs and send all logs via Skype chat for the time being. I will make a phone call when it stops.

Since Mojo stops frequently in a restartable state, I will notify you when it stops. It does not restart automatically because it is necessary to visually check for print abnormalities.

Library used

• Skype4py (Connect with Skype for Desktop)
• watchdog (watch the Mojo log)
• numpy (used to read logs)

How to use

Just set the path to the Mojo log and your Skype contacts If you execute it, monitoring will start

reference

• Skype4Py
• muddy brown thang
• Watchdog is very useful for file monitoring
