h1. Ironman Users Guide table{border-collapse;width:100%}. |={font-size:140%;margin-bottom:15px;background-color:#fdd}. This document is under development and is likely not accurate at this time. | {{>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. 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 running code based on a sensor template for pairing and secure communication with the Monitor | | *Jarvis* | A Java application that supports voice control of Monitor managed devices | |!http://redmine.graphics-muse.org/attachments/download/114!| |={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.| h3. Security Ironman supports AES encrypted communication with IoT sensors and Jarvis interfaces. 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 * The Pi 2/3 requires a 5V / 2A power supply. For best results, use a power supply rated to at least 5.25V to avoid under voltage conditions. * 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, switch should be connected to the Pi GPIOs to allow for pairing the Monitor with IoT Sensors and Jarvis interfaces. Jarvis. The ASCII diagram below describes the setup. The LED is lit in normal mode and off in Pair Mode until something tries to pair with the Pi. <pre> ___ Normal |---| Pair Mode --------- | | --------- pins --> | | | RPi GPIO 4 G 27 RPi pin 7 9 13 | | | +---LED---+ | | +---330 R----+ </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 look for the device name for the newly added card. 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 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_. <pre> 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 Start imrest web service on port 8165 for IoT devices and Jarvis interfaces. If in Config Mode Start wpa_supplicant on wlan0 Create uap0 device as virtual device on wlan0 Start dhcpd on uap0 Start hostapd on uap0 Start imwww for network configuration of the Monitor. /etc/ironman/iot Registration directory for IoT devices /etc/ironman/jarvis Registration directgory for Jarvis interfaces </pre> h3.
