In this document the term _host system_ refers to a Linux desktop or laptop that will be used to download and install software

onto an SD card.

h2. Overview

_*Ironman*_ is a home automation project based on the PiBox build system.  It supports a Nest-like monitor for controlling Arduino based sensors, cameras and remote voice control.

|={font-size:120%;margin-bottom:15px;background-color:#dff}. *Design Intent of the Ironman Project* |

|=. Mark I release is in progress.  Mark II and Mark III are future development plans.|

_*Ironman*_ consists of the following components.

| *Monitor* | The Nest-like control hub based on a Raspberry Pi 2/3 and the official 7" touchscreen display |

| *Sensors* | Arduino based devices, such as door alarms and cameras, running code based on a sensor and camera templates for pairing and secure communication with the Monitor |

| *Jarvis*  | A Java application that supports voice control of Monitor managed devices |

| *Controllers* | Network enabled control of Monitor managed devices |

h3. Security

_*Ironman*_ supports AES encrypted communication with IoT sensors and Jarvis interfaces.

h3. What it is

_*Ironman*_ is a do-it-yourself system, where you buy the parts and assemble them as described, modifying the provided code to suit your needs and handling flashing and maintenence.  _*Ironman*_ is designed to allow you to build your own home automation system where you specify the devices you want to control and how you want to control them.  

h3. What it is not

_*Ironman*_ is not a product.  It is not intended for anyone other than Makers (aka DIY'ers) who like to tinker and see not just how to assemble things but why they actually work.

While the Users Guide is intended to bring up a currently working version of _*Ironman*_ with limited sensor and camera support, if you aren't prepared to deal with writing code or flashing devices and dealing with electrical circuits then _*Ironman*_ is not for you.

h2. The Ironman Monitor

The _*Ironman*_ Monitor runs on a Raspberry Pi 2 or 3 and provides a central hub for management of home automation devices.  It uses a 7" touch screen display and a mechanical switch to manage pairing with IoT devices and Jarvis interfaces.

h3. Installation Prerequisites

* A "Raspberry Pi 2 or 3":https://www.adafruit.com/product/3055

* The official "Raspberry Pi 7inch touchscreen display":https://www.sparkfun.com/products/13733

* The Pi 2/3 requires a "V / 2A power supply":https://www.adafruit.com/product/1994.  For best results, use a power supply rated to at least 5.25V to avoid under voltage conditions.  For ease of use the power supply cable should include an "on/off switch":https://www.adafruit.com/product/2379.

* The Pi 2/3 requires a microSD card that is at least 4GB.  A mechanism for using the SD card on your host system is needed, such as an SD card USB adapter or an SD port on your laptop.

* A mechanical switch, such as a "SPDT":https://www.electronicshub.org/switches/#Single_Pole_Double_Throw_Switch_SPDT, should be connected to the Pi GPIOs to allow for pairing the Monitor with IoT Sensors and Jarvis interfaces.  The ASCII diagram below describes the setup. The LED is off in normal mode, lit in Config Mode, and off in Pair Mode until something tries to pair with the Pi which then turns on the LED for 3 seconds. Config and Pair mode operations ared discussed in later sections.

</pre>

* You will need to have sudo access for your Linux user id.

h3. Generating the SD Card for the Pi

* Download the RPi 2 Development Platform 

** _wget <url>_

** Unpack the archive to a directory called *image*.

* Download the _*Ironman*_ Package Collection

** _wget <url>_

** Unpack the archive to a directory called *package*.

* In a terminal window run: _dmesg -w_

* Insert the microSD card and note the device name displayed for the newly added card as displayed in the _dmesg -w_ terminal window.  It should be something like /dev/sdb or /dev/sde.

* Kill the _dmesg -w_ command with Ctrl-C.

From the *image* directory

* Format the SD card

** _sudo ./mksd.sh -d <device name>_

** where <device name> is the name you noted from the output of _dmesg -w_.

* Mount the boot partition from the sd card: 

** _sudo mkdir -p /mnt/boot_

** _sudo mount <device name>1 /mnt/boot_

** where <device name> is the name you noted from the output of _dmesg -w_.

* Install the Development Platform to the SD card

** _sudo ./mkinstall.sh -b /mnt/boot -d <device name>2_ 

** where <device name> is the name you noted from the output of _dmesg -w_.

From the *package* directory

* Mount the root partition from the sd card: 

** _sudo mkdir -p /mnt/root_

** _sudo mount <device name>1 /mnt/root_

* Copy the _*Ironman*_ Package Collection files to /root of the root partition on the SD card

** _sudo cp *.opk /mnt/root/root_

Make sure all writes to the SD card have completed

* _sync;sync;sync_

Unmount the SD card partitions

* _sudo umount /mnt/boot_

* _sudo umount /mnt/root_

Remove the SD card from the host system and insert it into the Raspberry Pi 2.

h3. First time boot

Power on the Monitor and wait for it to complete installation.  During this time the display may be upside down.  

Once the display shows two xterm windows it is ready to complete installation.  Type the following command to install the _*Ironman*_ package collection.

  opkg install *.opk

Wait for this command to complete, then reboot the system either by power it off and back on or by typing the command 

  reboot

The Monitor is now fully installed and ready for use.

h3. First time configuration

Turn the power off and set the Mode switch to Config/Pair, then power the Monitor back on.  The LED should light indicating the Monitor is ready to be configured.

Use a smartphone or laptop with wifi to connect to the "ironman" SSID.  The default password is _ironman1_.  Then use a browser to connect to the Ironman web UI at 

  http://192.168.36.1:1337

The display should be as shown in the adjacent photo.

h3. Network configuration

wlan0

* This interface is used for configuration of the Monitor.

* Configured on the 192.168.36.0 subnet.

** See /etc/network/dhcpd.conf.aponly

uap0

* This interface is used as an access point for IoT devices.

* Configured on the 192.168.3.0 subnet.

** See /etc/network/dhcpd.conf.uap and dhcpd.conf.uap.tmpl

** The template is used to change the base subnet through the web interface.

** The SSID is _ironman_.

Pair/Config button is GPIO 4 (RPi pin 7)

Pair/Config LED is GPIO 7 (RPi pin 13)

	LED should only be lit on boot if button is enabled (in Config mode).

		In this case, we're in Config Mode to configure the networks.

		The web server (imwww) is on SSID _ironman_ at 192.168.36.1:1337.

	LED is off on boot if button is disabled (in Pair Mode).

	If in Pair Mode

		Start hostapd for aponly

		Start dhcpd for aponly on wlan0
