House alarm system based on ESP32

Copyright (c) 2017, 2018 by Danny Backx

This alarm system is designed to work with a bunch of similar controllers.
You can choose which hardware and capabilities go in each individual controller, and configure them accordingly.

The software needs a small amount of configuration to talk to the hardware.
Currently setup is to hardcode, partially as a security measure, configuration (small JSON texts).
An evolution could be to add GUI to configure modules via the touch screen.
No (network) remote configuration functionality is built-in, to prevent making the system hackable.

It needs to be built with ESP-IDF, the build environment recommended by Espressif.

Components required (you need to put these in components/) :
- arduino (https://github.com/espressif/arduino-esp32.git)
- espmqtt (https://github.com/tuanpmt/espmqtt.git)

Arduino libraries (these are already copied in libraries/) :
- TFT_eSPI (Bodmer's stuff with small changes)
- Timezone
- arduinojson
- rcswitch
- rfid

Hardware platform :
- ESP8266 and/or ESP32
Choose what you like, have, or need. Most importantly : the ESP32 has more pins.
An ESP8266 with an OLED and a radio is out of pins, if you need to put more hardware in one box, you need an ESP32.
An ESP8266 with OLED and PN532 card reader also has just enough pins.

I have a PCB design that can be used to build a controller module with minimal wiring.
See my project on easyeda.com, or the copy in pcb .
The v1 has one known bug : the radio data line should go to esp32 pin 27 instead of pin 22.
