This project does a few things for me.First, I use the Pi to control the GPIO pins so I can test various things in the house and send a message via the cellular modem on the Particle Electron.
One example is if the house loses Internet (the Pi can’t ping a webpage), I get a notification on my cell phone. Another reason is if the house loses power, (the Pi turns off), the Electron sends another notification since it’s on a battery backup.
This Pi also has a USB modem attached to it, and using NCID, I’m able to receive a notification of who is calling my house phone on my cell phone.
