ESPEasy notifications

ESPEasy notifications are to be used in combination with rules.

For example, to send a message on system boot use a rule like this:

on System#Boot do 
   notify 1,system is started

Creating a paper-mail to email gateway

I used notifications in combination with Deep Sleep to create a system that notifies me when I have new paper mail in my actual mailbox:

Hardware

• Core: esp-12-f because this is low power already. (no voltage regulator and usb-to-serial interface that draws current)
• Casing: Google for Waterproof Clear Cover Plastic Electronic Box Project
• Magnetic microswitch: Google for something like 10pcs/lot Wired Door Window Magnetic Sensor Switch

For power I used an old powerbank, those you use to charge your phone. Most power-banks use lithium cells that are a perfect 3.3 volts. And they are easy to charge as well. :)
