{{>toc}}
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.
* A keyboard is required for initial installation. A "wireless keyboard":https://www.adafruit.com/product/922 should work as will a wired keyboard. The keyboard will not be needed for normal operation but can be helpful in debugging.
* 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. A Fritzing Diagram (attachment:IronmanMonitorSwitch.fzz) is available for this hardware component.

* 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 initial installation is complete the display will be right side up.
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
!>{width:300px}ironman-config-ui.png(Ironman Config UI)!
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. There are two network domains to configure, as described in the following table.
|_. Domain |_. Description |
| Internet Connection | This is how the Monitor will connect to your home network. |
| Sensors Network | This is how the Monitor will communicate with your IoT devices. |
After both networks are configured, power off the Monitor and set the Mode switch to Normal, then power the Monitor on. The Monitor is now ready to use with IoT sensors, Jarvis and controllers.
h3. Network configuration
The Monitor's hardware supports WiFi B/G/N networks. However, in order to use the Monitor as both a WiFi client on the local
network and as an Access Point for IoT devices, only G networks are supported by the Ironman software.
h4. Internet Connection
The Internet Connection domain configures the Monitor to connect to your local network.
|_. Field |_. Description |
|Location |Unique name for this monitor, such as Bedroom or Office. This name is used to identify monitors by name via commands from Jarvis or other remote controllers|
|SSID |Network name configured on your router for your local WiFi network. |
|Security | Type of security used on your router. Only WPA2 Personal and WPA2 Enterprise are currently supported. |
|Password | Your router's password, specifically for the SSID entered previously. |
The *Show Password* button will display the password typed in the Password field. By default this button is not enabled, causing the Password field to be hidden using asterisks for each character.
h4. Sensor Network
The Sensor Network domain is used to configure the Monitor's private network used with IoT devices. Data on this network is not routed to the Internet Connection and data from the Internet Connection domain are not routed to the Sensor Network.
|_. Field |_. Description |
|SSID |Network name for this private WiFi network. This name will be hidden on Wifi scans.|
|Channel | Channel to use. Select a channel that has low use in your neighborhood. Only a subset of channels on G networks are available. This will be addressed in future releases. |
|Password | Password IoT devices should use to gain access to the specified SSID. |
|Static IP | An IP address to give the Monitor as it acts as an Access Point. This should be a Class C subnet for the network, which limits the number of IoT devices that can be managed by a single Monitor to 254. |
The *Show Password* button will display the password typed in the Password field. By default this button is not enabled, causing the Password field to be hidden using asterisks for each character.

h3. Configuring IoT Sensor Sensors
h3. Sensor Types
There is currently only one sensor type: imlightsw (light switch).
The sensor template GIT repository is intended to be used to design additional sensor types, such as door and window alarms, window shade controllers, environment sensors and so forth.
h4. Light Switch
<pre>
TBD: show screenshot of fritzing diagram for light switch board.
</pre>
h3. Flashing the firmware
<pre>
TBD: show screenshot of fritzing diagram for flashing board.
</pre>
h3. Power On
An IoT sensors must be configured to operate on the same network as the Monitor's Sensor Network. Once this has been done the IoT sensor and the Monitor can be paired. An IoT device can only be paired with a single Monitor.
h4. Configuring an IoT Device Network
* Set the Mode button to Config.
* Power on the IoT device.
* TBD
h3. h4. Pairing an IoT Sensors with a Monitor
* With the Monitor running, set the Monitor Mode switch to Pair.
* Power on the IoT Sensor and wait for it to pair with the Monitor. When it's done, the LED will light for 3 seconds.
* Disable the Mode switch on the Monitor.

|={font-size:140%;margin-bottom:15px;background-color:#fdd}. *WARNING!* |
|={font-size:120%;margin-bottom:15px;background-color:#fdd}. Leaving the Mode switch turned to Pair will allow random devices to attempt to pair with the Monitor. This is a security risk. The Mode switch should only be set to Pair long enough to pair with an IoT device. |
